Class A = a heater that happens to produce music.
Class B = produces music, but barely.
Class A/B = can't decide between heating the place and producing music.
Class D = a very fast morse code generator that still produces music.
What about the c wave proposed by mark Levinson on his Daniel Hertz Maria amp?
Fantastic coverage and I am hooked! Can’t wait for the next one.
I always learn a lot from your videos. Thank you.
Great video - first time I've tried one of your podcasts and very glad I did - both informative and educational - looking forward to more like this in the future :)
Great video/ podcast guys!
Thank you.
At the end John mentioned the acoustic treatment of his office. I have to say that it is much more pleasant to listen to John‘s voice in his treated office than Srajan‘s echoing voice.
That is SO interesting! Thank you John and Srajan. Your humility and knowledge are very much appreciated. Keep on the good work!
Thanks for a new 2024 podcast. Always interesting to learn about new equipment. I’m an A/B guy. I’ve had amps that have lasted for decades. My 200 WPC into 8 ohms Rotel amp paired with its matching preamp is the perfect balance of performance, looks and cost IMO. I can run it for hours cranking out classic rock and it never gets hot or triggers a protection circuit. Hopefully other classes of amps will advance the science of hi-fi and pass the test of reliability over time. Keep up the good work!
Thank you both for your insights and the entertaining way you present. I always learn so much and have a great time doing it.
John & Srajan, that was nothing short of an excellent presentation. Thanks so much, held my interest the whole way through and yes both entertaining and educational. Bravo !
IT guy here, tnx for the amp types explanation! But the network part makes no sense, the TCP/IP implementation already solve this problem, and send/receive buffers take care of the timing issue. So… yes fiber optic can have more length and is easier to route, but the audio is exactly the same.
that's what I'm saying! these old guys think there's a difference in audio quality of the same file type played over Ethernet or Cloud. I can almost bet the file being streamed from the cloud is compressed and possibly a different file type altogether
@@TecraTubeI’m new to this but I think you need a DAC to play anything over 48khz on Apple Music.
Agree with OP, but in addition this ignores the whole concept of buffering. Timing of the error correction adding noise is nonsense as the data will get there completely or it won’t and there will be a timeout. The data will not be changed. There probably is an audio discussion to be had regarding streaming versus local, but this is more around the codec/compression/bitrate or other things the streaming service may be doing at the data level, fidelity loss in local networking isn’t a thing unless something went really wrong.
Very informative and one of your best videos to date. More of solid state and tube amplifier design would be nice.
I’m putting my money on A/B. Literally. A channel just died on the 52 year old Sansui AU-555 that’s been the cornerstone of my system since the summer I got married, so I bought a Schiit Vidar, which is shipping Today! 🎉
I have the same amp!! Did you like when alive? I got it from my father and I can hear a bit of background noise, but other than that it sounds pretty good to me
Why not repair the Sansui?
You could have saved a little more and gotten Orchard Starkrimson monoblocks. Oh well, enjoy the Schiit.
Go get it serviced! Those vintage amps are tanks when properly serviced, will last another 50 years easily.
You should get the Daniel Hertz Maria, class d is the future 😆
Thanks John,
This is public service broadcasting, you Inform, Educate and Entertain.
Very good video with a flood of infos. Wow!
Well thank you JD and thank you Srajan for another entertaining and educational podcast, please keep them coming.
This is a great guest--I enjoyed the discussion
Good morning from Singapore.I am happy with my tube amp and my YBA intergrated amp since 1979.I am also happy with my Thiel cs22 and snell type d speakers.
Class D will eventually become the norm. Too many advantages. Pro audio has been class D for a long time.
Or you never had a great class A amp.
The Vandersteen model 5 used 2 12” woofers in a isobaric configuration for below 120 Hz, the two woofers think the box is twice the size, it also offers more work for control. I’ve made a few subs using this configuration with excellent results
@8:00 I was listening to this podcast and wanted to add a correction to the Class A amplifier discussion: Class A amplifiers have transistor(s) that are biased half way between the voltage rails, normally ground (0V) and the positive voltage rail, so there is no transistor handling the positive swinging signal and the negative swinging signal it a transistor or group of transistors handling the entire signal. The transistors are constantly on and conducting current with that bias scheme therefore it waste power even in idle and gets extremely hot. They might sound good but it is taxing on the transistor which is why they have extremely large heatsinks, and your wallet via the electric bill.
Thanks for the podcast. It was a really nice breakdown of the different Class of amplifiers for network engineers 🙂 A much better usage of galvanic isolation is the demarcation point of network service into power substations where the results of electrical ‘crossover’ from switchyards into the telecommunications network can be much more serious than signal interference 😉 Also Cat5, 5e, 6, 7, etc. UTP, FTP, etc. are indeed most widely used in Ethernet LANs but they are not Ethernet cables in the same way that the multi-mode fibre optic cable that Srajan was holding is also not an Ethernet cable. Capable of transport Ethernet frames across networks yes, but that is a sweeping generalisation. I love your stuff but sometimes us IT folk get triggered too 😁
I'm in the market for a new amplifier, so this was rather well-timed, John!
Great video. I have the McIntosh 252 that is an Hybrid Class A & Class D, sounds amazing, but more and more hear and read that Class D is evolving to even surpass Class A or AB in many aspects.
Very interesting and informative
ATC active speakers all are Class A/B amplified, top to bottom. In addition, the amp modules can be taken out and shipped back individually.
I am really happy that AGD was mentioned by Mr. Srajan as those amp are damn good. Using Audion MK iii and I really happy of having that, my another amp is class A push-pull - Cobra by Audio Note.
I own the AGD Audion Mkiii mono blocks as well and they are the real deal! They outperformed my Parasound JC5. I hope they are reliable because I plan to keep them for a long time and I have no idea what I would replace them with?
Linn has made AB amps with SMPS for a very long time
They also drove isobaric speakers actively in the 1980s and are still pushing active. Interestingly very few customers seem to like separate amps for active systems which opens endless possibilities. But also lots of cables and boxes.
I moved on over 55 years into HiFi had it all A, AB and Tube and now D and don't look back
I'm buying the NAIM STAR and KEF R3 next month as a bedroom stereo visited a sound lounge at my local dealer and they sound fab. The fact I can rip my CD collection to a SD memory card in full fidelity is fantastic. Upgrading from a Denon HEOS N10 and Monitor Audio Bronze 2
Back in 2013 I replaced a pair of Cary 300SE monoblocks amps (Class A, 9watts - yes, nine watts - per channel) with an ARCAM AVR600 because I wanted multichannel audio as an option whilst still focusing on stereo listening. I was very pleased with its performance versus the superb Cary monos for my ALMARRO M2A speakers.
It was only later when I found some technical resources on Class G amps (as in the Arcam) that I understood this amplification was Class A up to 30 watts per channel. I am still very happily running the ARCAM AVR600 (only ever used as an amplifier, not for video processing).
An interesting coincidence for me in John's podcast is that he is partnering with Srajan. My ALMARRO M2A speakers are from 2005-10 period and I have only ever found two reviews of them and one was by Srajan on his 6Moons site....and a glowing one!!
Thanks to John & Srajan for offering more confirmation of my original decision re Class G amplification.
On the Naim Uniti Nova PE, it retails in here in the uk for £8600. I listened to one at Sevenoaks SAV. I ended buying a Naim Uniti Nova headphone edition with the NAD m23 power amplifier and saved £3000 on a better sounding unit with more power, 200w compered to 150w. Plus balanced headphone connections and all the offerings of the PE edition apart from HDMI input. The Naim pricing of the Nova PE unit is just wrong IMHO
Hi, I have the standard Nova. I didn’t realise there was an headphone edition? Is this new? I know there is an Atom headphone edition as I’m looking to buy one.
That's quite smart, I like it.
Sorry my typo error. It is the Naim Uniti Atom HE I bought with the NAD M23@@deanwhiteley3065
I have had a KH 150 A active monitor from Georg Neumann, Berlin, a subsidiary of Sennheiser, for 10 years. And I am very satisfied. The monitors are fully equipped with Class D amps and switching power supplies. The XLR cables are from Tonstudiotechnik Funk, Berlin. The sound is very balanced and homogeneous, the treble is a little cool, as there is a lot of steel furniture and glass-fronted pictures in my room, as well as many windows and doors with glass inserts. Sibilants are very clean, especially with the sibilant-critical XRCD Companion (live) by Patricia Barber. The preamplifier is McIntosh MHA 150, CD transport MCT 80 from McInt and two professional MC3plus reclockers from Mutec, Berlin. Turntable: Denon DP 3000 NE Directdrive with Koetsu Rosewood, Lyra Delos, Denon D 103 and Miyajima Zero Mono.
Vintage high class preamp and a class D Poweramp. The Perfect combo for me
I used to build Isobaric enclosures using MB Quart drivers for car audio installations. They were very efficient, so easy to drive with great results on a low budget
do they switch on and off or positive to negative in class b ?. the crown dc300a is class b and certainly doesn't sound unpleasant . i am curious to know if there are harmonic artefacts that make it down to the audio band with class D .
I don't know if anyone already mentioned it but your voice is very relaxing. I regularly find myself falling asleep while watching your videos... Kind of strange but yeah, I thought you should know
Me too! 😆
Really? Haha, man that’s an awesome feature! 😄
@@DarkoAudio 🤣 good one
So relaxing for me too. Also nearly falling to sleep, nodding up and down. Luckily we got YT version so it’s easier to stay focused. But out walking or in the car, the Podcast rules. What about John reading whinny the Pooh 😂 at night. Love your work.
I've got a March Audio amp that uses the Purifi modules (P452), and it's wonnnnnnnderful. Incredibly cool and efficient, sounds wonderful, and in the realm of hifi, and incredible value at less than $2k USD.
@46:30 Technics uses GaNFet in its SE-R1 and SU-R1000....fun fact, GaNFet's are used in AESA Active Electronically Scanned Array radars in modern 5th and 6th generation fighter jets. Pretty bad a**, right?
I've been through Naim AB (Nait 5i; 1552XS,155XS; 202/200) plus all the power supplies, which for the 202/200 was a TeddyCap and a Napsc and I've gone to a NAD C298 power amplifier with the Purifi Eigentakt class D modules fed by a Chord Hugo TT2 (which is DAC digital preamplifier) and I wouldn't switch back. I've replaced 8 boxes (DAC+PS; Pre+2PSs;Power; Headphone amp+PS) with two and it sounds crystal clear which I prefer. Less is more for me.
Why does the HDMI on all Naim gear look like an after thought that was just bolted on, on a premium price product?
Im vintage haha. Old school tube amplifiers in pre and poweramps two monoblocks working in Class AB push pull. At 23 watts with 91db speakers.
All homemade. I have lend good a Class D amplifier. A Primare A35.2 power amplifier, i must say Class D today with this brand i was suppriced it was musical.
But a more lifely musical from my tubes had more darkness where music is better placed. But overall for what is possible today with Class D it is wonderful. Little expensive too😏 nice video explanation about Class a a/b and d
about time🤙🏼
Thanks, I've always been confused.
Isn't KEF KC62 subwoofer isobaric design as well?
After decades of Class A/B (Classe Audio & PASS Labs) I recently switched to Class D with the Emerald Physics EP600.2SE. It includes a tube buffer stage that can be switched in and out on the fly but I find that I only engage it for serious listening sessions. The most musical and powerful amp I have owned, dead quiet, and it only weighs 15 lbs (6.8 kg) so rearranging my equipment rack won’t hurt my back (looking at you PASS Labs X5).
John, please consider reviewing AGD Audion monoblocks! I would love to hear your impressions. Tx!
Didn’t Elac first active speakers use class a/b amplification? Thanks again for putting out another video with Srajan. Keep you the great work!
My favourite HiFi youtuber.❤
As Paul McGowan said a couple of years ago, Class D amplification continues to change for the better. Some peoples opinion of Class D has not changed.
I just recently discovered this guy and his fabulous reviews (looking into getting a pair of KEF R3 metas), started watching this video and noticed Pet Shop Boys Heart in the background. Now I’m an even more massive fan of him! BTW, a review of the Arcam A15 and how it is with those KEFs would be nice!
Srajan's reviews are just in another level compared with the most of the reviewers today
I have an Arcam Class G integrated amp and I love the sound it produces. Maybe you should review the new Arcam Stadia A25.
Didn't know where to post general comments and review requests, so I'll do it here. Just wanted to say that I throoughly enjoy your content, and I've been following your TH-cam channel for a couple of years now. Your channel is very informative, cuts through the BS, and I appreciate the honesty you provide. Based on your review and recommendation, I purchased a set of Monitor Audio Silver 100 7G speakers (in British Racer Green, not because I'm from the UK, but because they look awesome) about a year ago and was left thoroughly satisfied with the purchase.
I recently saw your review of the Sony A-306. Was wondering if you had tried out the NX-707 (i.e. the Japan version, and not the US version which is extremely power limited) and what your thoughts were on the device? Also, as an audiophile, I was wondering if you have a discrete soundcard for your PC and, if so, are there specific use cases where you feel like it's worth the investment? Thanks!
Isobaric can be faced the same way and move together or be in a clamshell and work in a push pull configuration. The main reason why you don't see them that much anymore is cost and also we have better drivers than 60 years ago when they needed huge cabinets for big sound. When they came out with the AR sealed boxes that kinda changed everything.
I have a unity Nova and it's a wimp in terms of power. I've had it shut down a number of times playing it loud in a 12x14 bedroom with a number of different speakers. It's supposed to have 80 watts which should be plenty but for whatever reason it's a wimpy 80 watts in my world. If you like to play loud and want to use a typical lower efficiency box speaker you may be disappointed. I'm sure others have had the same problem, hence the PE version.
The discussion on use of glass fibre/Ethernet/galvanic isolation immediately reminded me of Small Green Computers and their network streamer product line.
I started using their microRendu many years ago as a Roon endpoint, but benefitting from its galvanic isolation. This early little marvel was eventually replaced by optical-fibre linked modules ("Optical Rendu").
In the end I did not understand whether Srajan's approach was in any way different from the SMG product lineup.
I have a 125W class C amplifier here that sounds great as long as you drive it with an FM signal centered on 145Mhz.
I have listened to Naim PE class D in Bristol and it sounded nice to me. Even in untreated hotel room. I think that’s the most important … either one like the sound or not… does not matter how it is achieved … at least to me. It’s like wine … one can do so many manipulations in growing or making it but what matters is the end product and our personal taste. A lot of good amps from Aavik Daniel Hertz are class D now and they do sound nice so maybe it’s just a simple evolution ?
I would love to see you review the Def Tech D-11's. I just purchased a pair and I am absolutely pleased with them in every way but given that I value your opinion unlike any other, your review of these speakers is important given their value to sound quality proposition.
The cartridge that Srajan is referring to is known as Small form-factor pluggable (SFP), they come in different types and speeds based on your
cables and endpoints.
Only class D I've had was a Ncore-based one. Bought in to the hype a bit. Stunning clarity and definition, bass in particular, like nothing I'd had before in various amps - AB solid state, valve, and hybrid/MOSFET ones. But over time it didnt feel right. All the detail was there but something unnatural about it - especially the tip end. Again, feel. Went back to AB amps and now a class A.
I’ve just swapped my Roksan K3 (A/B) for a Cambridge Evo 150. Did it to get down to one box. Different sound but I’m really enjoying the convenience and more importantly the sound from the Evo. Bass is great and tight and it’s more revealing. I think it’s more neutral in its sound. I wonder whether class A/B is warmer but more coloured? Hmmmm.
I tried the raal ca1 and returned them as their spl was insufficient to product and enough volume for me. I undersand that these new models have higher spl and might work for me.
Tried class D. Punchy as but I was soon back to A/B.
I have a pair of Classe Sigma monoblock amplifiers and they sound wonderful, transiently fast, but not lacking any warmth.
Hybrid integrated amplifiers combine class-A preamplifier topology with class-A/B or D amplifier topology. I'm well versed in amplifier topology and I think seasoned audiophiles are too or at the very least they know what they like and which brands make a preferred sound signature. Personally I prefer the sound signature of the current generation McIntosh solid state class A/B amplification for speakers. There's a directness to the sound signature or maybe a better description is a coupling effect, this did not impress me at first but now everything else sounds broken to me that does not have the directness of McIntosh amplification, I shouldn't say broken because I love the sound signature of 300B triodes and triodes in general, I love the sound of budget tier amps like Onkyo, I'll mix it up to keep things interesting but I always go back my McIntosh rig after a few days, there's something about those McIntosh output autoformers that can make other amps sound broken in direct comparison
I believe the ELAC Adante AS-61speakers designed by Andrew Jones has a similar (not isobaric) type of double woofer construction. One is a passive radiator, though. That speaker apparently didn't measure very smooth.
I own two GaNFET amplifiers--the AGD Audion Monoblocks and the Technics SU-R1000. They are both superb and compete against anything. Very much the future of Class D.
A big part of someone’s preference is experience and exposure. I grew up listening to Class AB stereo sound systems and old school vinyl and radio with my old man. Then I migrated to CD’s , tried the mini disc, ipod, and streaming and now my primarily listening is CD with a class AB amp cause to me, that just sounds naturally better, the sound brings the air around me alive and full bodied to my ears. Streaming is too clean and sterile, the sound has no body soul whatever you want to call it, just doesn’t make me happy. That’s just me
I’d love to hear an expanded discussion on WiFi vs Ethernet for streaming. Perhaps a video showing and discussing side by side comparisons.
Why would they be different?
As a former network engineer, I was about to say something... but I never would have thought about audio streaming and the latency factor effecting audio. Does the client not account for that and add some buffering so that no frames are lost?
Just think about the potential latency you can get because of TCP/IP packet resend depending on network conditions, topology etc. And streamers can add additional layers (on top of TCP) of error correction techniques (forward error correction, back error correction, etc) to ensure quality on the media signal. So yes, you always have a buffer in the endpoints of media streaming to ensure you will not get drops in time dimension.
Musical Fidelity made a class B amp back the 80s - the B1. I have one and it's great.
As an ex electronic engineer and hifi enthusiast, I really enjoyed this video.
Me too. (ex-EE), but it was a bit tortuous without signal vs. time graphs!
I upgraded from Class A/B to a pair of Purifi Class D mono blocks. I'm very, very happy with them. It was definitely an upgrade, sonically.
I really enjoy that podcast.
Great explanation on the class A, A/B and D amp debate.
I’ve only just taken the plunge and gone for a Nad 298. Class D is the future for amplification isn’t it?
Regarding the new Naim £10k all in one. I just don’t get it, but then I never have. Why would you pay so much for what is available elsewhere for so much cheaper? Is the volume knob that good? Are Naim devotees, that devoted? I thought it was all about their power supplies and rhythmic orientated sound? Won’t a D class module that’s also in a £1700 Nad or a £1200 Audiophonics have more or less the same sound signature?
As you say, it had better be good.
Cheers
I switched from a Roksan Michi X3 AB to an Audiophonics Purifi 400wts at 4Ohms and couldn't be more satisfied with how its driving my Dynaudio Evoke 50s.
With my Parasound JC5 power amp I'm
Class A/AB and love what itdoes because of how it sounds not because of how it works.
Great conversation, more content like this please.
I picked up a Class-A Portable AMP by Astell&Kern for my on the go needs, It sounds fantastic.
I had the chance to listen to the Raal Immanis at the world of headphone (Heidelberg). I was really impressed. Never heard such a good sounding headphone.
Hey John, your started to cost me a packtol : cxa81 r3meta adi2dacfs as a preamp but this one is definitely out of my pourse 😅
KEF R3 Meta in the background 😎
My Rotel A12 amp has been great. 60wpc and class A/B design.
Thanks for sharing this. Could you recommend a top quality external USB CD player to rip CDs from to the computer in the highest bitrates, thanks.
Personally I would use a good quality external computer style cd drive for ripping, with software such as dB Poweramp. Ripping will be much faster and just as accurate.
The properties that make a good cd player are very different from a good cd ripper. Having said that, there are now a couple of players with usb outputs, the Schiit Urd and Shanling ET3 ( my personal preference between the two), but I have no idea if either can be used as a source for ripping.
Watching this made me realise I am not an audiophile.
On the contrary the fact that you watched it confirms that you are :)
Please explain. How do you define "audiophile" and how did watching this video cause you to realize that you are outside of that definition?
Class D. Lyngdorf TDAI 3400. Wonderful sound. I’ve had a lot of AB, A, tube and the Lyngdorf is a clear winner.
Because you switch at some certain frequency doesnt mean that the switching harmonics cannot be at higher frequencies. Switching harmonics of a PWM modulated converter is generally at mulitples of the switching frequencie and the corresponding sidebands.
Exactly, because it is the speed of the rising and falling edges that create the very high harmonics. So an amplifier that switches at a "rate" of say 550KHz can generate harmonics up into the 10s of MHz.
I have always had ab amplifiers and recently I bought a crown xls drive core class d to power my diy subwoofer because it can be bridged and has a crossover. I got curious and wanted to hear how it sounded 2 channel stereo on my speakers and it sounds really good. I have really nice sounding speakers that are efficient but can handle a lot of power and have a lot of bass and the crown handles them with speed. I even heard rim shots on the drums I never heard before. I just ran a cheap tube pre amp with it just to see what it could do and know I want to get another one for my subwoofer or maybe a different class d amplifier like a xtz . I think people just have it in their head class d sounds bad . But a lot of people like the xls crowns
Oh, half-WIDTH box. I thought you said half-WIT! I was thinking, finally, a box for me!
Lol
Lol I heard the same thing! …and I was going to actually accept it as a subtle bit of Darko humor.. ;-P
Class D finally, finally (when looking at the best designs) can compete with A & AB.
I use the LHY FMC in twice, and i love it i goes from my Innous Phoenix NET to the LHY FMC and then to the Lumin U2 the Sound bölowing my mind, after this i make a line from my router withe the LHY SW6 over Fibre Optic to the Second FMC and this was so amazing what are is make with the music.
Another speaker brand, Audiovector from Denmark use an isobaric bass driver set up in their R6 and R8 Speakers, very neat use of technology !
Much Audiovector love here.
🇩🇰👌🏻
@@marcus1970 just picked up a set of the new qr5 se.. almost broken in and sounding great !
Class D amp Hypex Nilai 500 DIY ….. I use two stereo 2X250W Not bad ;-)
On the topic of fiber optics VS ethernet..... That's why they have memory buffers in modern switches and routers. So it would not matter timestamp wise. The data from a source arrives way faster to the destination than you can listen to. So error handling would have plenty of time to correct the signal if there was any fault in the TCP/IP packaging. There is also a memory buffer in your DAC or streaming service receiver, either it being a RaspBerryPi using Roon or Volumio or a fancy streamer like Eversolo DMP 6 or 8. Therefore, this 'Fiberoptics' is nonsense. Look to improve on speakers, DAC and source files instead for the best gain in sound quality. Spend your money wisely, to gain maximum return.
I'm learning but if I'm happy with my speakers and avr your saying don't get buy an amp? But if I upgrade my speakers that would be way more money. So can people blind a/b test their speakers with an amp off and then on, and it's not really a big deal? I just thought an amp would improve the speakers sound a bit.
I've got a pair of audio teknica electrostatic headphones, not sure how they work, but the have a box which is connected directly to you power amplifier speaker posts.
I've been a class A b user forever but when I got a great deal on a Peachtree Nova 150 I can honestly say it's as good in my opinion as anything a b in the past 20 years !
I use my audio analyse PA 90 , serviced 2 years ago and the mechanic said he will never do it again ,inside its a horrible amplifier because it’s French lol but the sound is still awesome 🙌🏾 and yes it’s becomes hot and use a lot of power.
I've gone from budget Class A/B (Denon) to budget Class D (Topping, Fosi, Crown, Micca) then back to budget Class A/B (Denon AVR). In the budget segment at least - I prefer the A/B sound - sounds fuller but definitely less resolving
It does look sexy, but Naim really are taking the Micheal here. You can only live off your naim (see what I did there) for so long. £10K for a Class D, 150W. I don’t care what the amplification method is, does it sound good? Price wise, they really are pushing the limit to what they can get away with. I suppose they’ll no doubt introduce a power supply option for £5K even though it’s Class D. 😂 I auditioned the original version and left it in the shop.
Agreed
Heating problems? With a LM 805 you get beautiful sound, plenty of power and fantastic glowing valves. It’s like a fireplace with great musical quality… and you can do tuberoling. When you got a transistoramp you are stuck! Please get out of this transistor trouble. I haven’t seen any propa’ review on tube amps on your programme Darko?!
What’s the readon for this?
You haven't seen tube amps on this channel because you haven't looked 😉
Room correction is nice to have
Everyone is so excited about the Nova PE, but I'm really curious about the CI-102 Uniti. It's designed for custom installations, sure. But it costs 1500 euros, it's tiny, quite nice looking, and if it sounds like a Naim it could be a bargain!
