Accuphase A-48 Amplifier: Pure class A thundering accuracy!

You can also pair an A48 to to just about any of their Class A integrated amps. I have an A48 paired with my E600. Together, they power two Chario Ursa Major floorstanding speakers. The A48 handles the bass section of the speakers. I also have an Accuphase DP-700 SACD player and C-27 phono amplifier. Very expensive, but worth it. I guarantee you'll be off the Hi-Fi merry-go-round if you invest in their gear. Also, their products are well built and last forever. You can pretty much take it to the tomb.

[@johngarbutt]

Fascinating. I have two monobloc class A amps and I love them. Class A may be power hungry but they work great. Sadly the Accuphase is way out of reach for most of us price wise but still interesting to know whats out there. Will keep it in mind for when I win the lottery.

Hello. Greetings from Spain. I've always wanted to have a class A tube preamp and a pure class A mosfets transistor power amp. For the preamp I think of a Primaluna Evo 400 and for the power amp this Accuphase A-48. My speakers are Pylon Amber MK2 that mount a pair of 12-inch drivers each and a compressor speaker for mid-highs that handles frequencies from 1250 hz upwards. I have a Yamaha A-S3000 that has plenty of power but not control with those double 12" drivers and I think this combo would be ideal. Enjoy this magnificent Japanese machine.

[@Stelios.Posantzis]

Judging from the views, there are probably eighty thousand people interested in this amplifier. That is incredible. Even if just one in twenty of those is interested in acquiring on, that is still a huge number.

As accuphase owner myself, get a accuphase preamp with it for starters. But tip from me and a fellow accuphase owner. Let them warm up for about half an hour or 3 quarters of an hour before using. Night and day difference. Fyi i own the c200x and p400. And my audio buddy has the c2410 and a46.

[@goldenears100]

I have not heard them myself but I know they make great equipment! What about talking about OTL's and Balanced XLR connections? No need for very expensive interconnects which usually suffer from runs longer than a few meters! Also, the Atma/Sphere Amps don't use Negative Feedback which causes distortion! The designer Ralph Karsten explains why and how things work on a TH-cam video from San Francisco Audio Society! I have been using Atma/Sphere Amps for many years now! Love them! They sound so Musical in all areas of Frequency and Soundstage and Depth! I no longer am using my Tube Pre Amp at this time because I am running my Ayon Tube CD player direct into my Mono Amps and also using an RC35 from USA Tube Audio that Enhances the Harmonics in the System! All Tube Design also! For Analog in my system I use a Passive device from my Pass Phono Pre Amp to the RC35 then to the Amps! I have been an Audio Consultant for many years now my and have tried many Tube Amps over the years! From Single Ended 300 B's to Class A to Class AB etc. The Atma Sphere Amps have given me the best sound I ever had! The tubes used for the Output are 6AS7 or 6AS7G and the Awesome thing is they don't have to be They run very low voltage and don't need to be Matched! Saves lots of money and those tubes are readily available and inexpensive! There is absolutely NO NOISE in my system from any Tubes or Output Transformers which caused noise in my to previous tube Amps! So why don't I see this discussion amougst other Audiophiles?

[@sidesup8286]

My first experience with Accuphase was their moving coil phono cartridges. They made them; there was the AC-1 and AC-2. They had a wonderful focus and imaging that most of the other MC cartridges didn't have. The word phase is in their company name after all, and they lived up to it. A most interesting brand. I am an experimenter though, and if I had $12,000 to freely spend on power amps, I would have probably bought some vintage legends, like the Halcro power amp or the Sony TAN-7B which uses Vfets. Have you ever heard a Vfet amp? They stopped making them years ago because of cost. They are the best sounding transistors ever made, I think, and they are from the 1970s, believe it or not. The upper model Vfet amps go for thousands of dollars on the vintage used market and they are grail and rare. Some of the amps had reliability problems, so Sony stopped making them. Rumours have it that pristine ones can stand up to the sound of virtually anything currently in the high end. The fist time I heard a Vfet amp, the electronicy white sound that I thought was part of the genetics of all transistors, that was alway a little audible to me, was suddenly and refreshingly absent. I guess transistors don't have to sound that way, I said to myself. The Vfets were so smooth and the tone colors so pure and deep. The Sony TA-N 7B amps, if you find one, are usually around $3,000 on the used market. Those considering them shouldn't worry that they're so many decades old, as far as their design. There were some people who really knew what they were doing back then, as far as aidio design, and they didn't cut corners like they do today. There were some Vfet amp models only available in Japan that some say would sound even a little better than the TAN 7B. Years ago, Nelson Pass of Pass Labs heard rumours that Sony found a big box of old NOS Vfets in their warehouse. He jumped right on them and paid whatever amount Sony wanted for them. He incorporated the no longer made Vfets into a few amp designs which he might have kept for himself. Not sure. They are wonderful devices. .

Very interesting, thanks for sharing that! Now I have another piece of gear on the list! Yes, Pass with his SIT amps gained lot of attention and are greatly acclaimed by the critics and public.

I think the champagne colour of the Accuphase is gorgeous in my opinion and I happen to like the look of McIntosh.
I had the privilege of listening to the Accuphase E5000 integrated and the McIntosh MA12000 integrated and I can tell you that I was really drawn towards the McIntosh. The McIntosh sounded so much more open, full, dimensional, ENGAGING and MUSICAL. The Accuphase E5000 sounds great and wow it looks beautiful! But for me I prefer the McIntosh MA12000.
Now all that said I bet the Accuphase Class A must be something extraordinary. Unfortunately I can't find one to listen to.

[@anadialog]

Hopefully one day I will try a McIntosh in my system!

[@Stelios.Posantzis]

6:18 If they have certified specifications, then I would imagine that means these are based on a number of samples provided (for each amplifier model and iteration, e.g. for the A48 they would need to provide samples for the 120VAC model, for the 230VAC model etc.) to the measurement agency issuing the certification. It is natural then that they will de-rate the performance figures obtained to account for sample variance. The certifying agency I would imagine would provide a statistical variance figure based on their experience from various such tests (and from the actual measurements of course). What this means to the consumer is that it is a statistics game so that with some rough probability (e.g. let's say 95% for the argument's sake) they will receive a sample with performance better than the figures guaranteed than specification. This could of course mean that the customer has a 5% chance (in our fictitious example) of receiving an amplifier with lower performance than the specifications. Again here I would imagine that there is a quality control process whereby they measure the amplifier when it leaves the soaking stage and after any basic control and safety tests are made. So the actual probability of receiving a sample with performance figures below specification would be far far lower than the certification process statistical error would prescribe.

[@arnoldschloss9634]

True, Accuphase is definitely a superior product, along with several other legendary brands. However, the ultimate make or break in sound quality, rests with the quality of your speakers attached to it- I have a vintage Sansui receiver that I originally had a pair of inexpensive bass-reflex speakers connected to and it sounded barely ok. As soon as I acquired a pair of Klipsch Heritage speakers, the difference in sound was absolutely stunning. I addition, the quality of your amp and speakers are both limited to the quality of your source material - just a case in point.

[@alphaniner3770]

I am curious what Sansui you have - my first amp (receiver) was a Sansui S-X700.

[@arnoldschloss9634]

[@alphaniner3770]

@@arnoldschloss9634 cool - a decade more vintage than the unit I used to have, and probably quite a bit better ;o)
- what is funny, is that many high end amplifiers, like the Accuphase here, partially try to go back a bit to the pleasant sound these vintage models can produce - reviewers nowadays often call that 'musical'. 'Resolution' and 'detail' are often confused with higher order harmonics that are in fact technical artifacts. Technically 'perfect' amps can sound pretty bad, especially with poor source material - but I guess that this is what you already said above.

While certain technologies you speak of in this video are truly not novel or new, some of those technologies do help in providing a better overall presentation. I personally would favor a much much higher power gain factor while maintaining class A OPERATIONS. Personally, if I did not already have my own full all stages dual mono designed perfected ultra pure power instrumentation graded amplification units that have no peer at ANY PRICE, I might consider a dual mono setup of these for a basic high quality system of low level listening and far better than basic quality that is sadly so common today.

Actually I bought an Accuphase many, many years ago. I still like English speakers so I will be buying the Sibelius speakers soon paired up with a Pass Labs int 25 amp. However the reality is that Chinese basic components are very sound and they have entered the hi fidelity market. Right now they are concentrating on products like the Korean Rose 150. But if they choose to move into the really high end hifi market they can do very well. The problem is the domestic Chinese market for these products are finite. Unlike electric cars where they are the leaders given their commanding domestic base. I would never buy a Tesla.

But seriously. 12.000 Euro seem to be insane to spent on an amplifier. It was, when I bought mine. In pounds in those days. With a by Räke modified DAT-Player. That was in? 1992 or so. Together with the Transrotor it is still a gear, hard to beat. After 30 years or so. When I calculate, how much I had to spend on cars in that period…😱 Ok. The cars I needed to be able to do my job.

Also they might receive complaints from Accuphase fans that prefer the needle VU meter look.

I understand and hate how high-end can't be more real life expensive, it's just absurd. In any case don't worry I will go down the ladder but I did and do want to explore also this world which I have only dreamed in my childhood. Actually my final goal is exactly that, high quality at the right price BUT I must explore and understand before following my path

@@anadialog Thanks Guido for the nice reply. It honestly does seem like your journey is most definitely taking you to some very nice places! 👍

The RRP in the US is apparently around US$18,500... 🤫

[@rainman3269]

$10 k isn't that expensive for such quality that you get ... 😎

Ciao , volevo mandarti un messaggio , ma avrai disabilitato l'opzione , perché non un bel video sulla manutenzione di lettori ,amplificatori,giradischi e piastre ? Per esempio su una piastra professionale ho visto che il vano per le cassette si apre con difficoltà non so se mettere qualche goccia d'olio tipo singer o balistico o grasso siliconico sulle rondelle e molle che permettono al vano di aprirsi e chiudersi ,insomma qualche un bel video sul manutenzione che si può fare a casa, sui lettori cd , vinile cassette ,amplificatori e diffusori .

[@anadialog]

Potrebbe essere ma non sono poi così ferrato sulla manutenzione se non I passaggi base che ho già presentato qua e là nei video...

One small guestion, CAN A48 drive Avalon Eidolon.

I wouldn't recommend it with 87dB of sensitivity

In the audio it sounds like an instrumentation amp is lab quality.
