"True class a" doesn't necessarily imply single ended. If the output transistors are biased such that you can swing the output to clipping at both rails, without either transistor turning off, then it's class A. If they turn off at some point, it's class AB. There is a "class A region" in a class AB amp, but that doesn't mean it's a class A amp, and in fact almost all audio amps are class AB, or D, (or one of the less well defined variants with any letter >D). Actual class B is switching at the zero crossing without an overlapping class A region, and class C (never used in audio) is when there's actually a dead band where both transistors are off .
Class A is not push pull. But most of the signal is expelled as heat. Class R and T amplifiers are my preference because magnetic field cancellation in your toroidal transformer eliminates much component humming allowing for customization of component placement for improved form factor and the inherent distortions that comes with tube amps can be modeled or simulated.
they used to put sand in speakers for damping. Pioneer I think back in the 60s. i heard a pair of the monitor sized ones in Guam (while in the USAF) that were very good.
Amps and DAC are horrific value for sound quallity in a chain. A more comfy listening chair is likely to improve your experience more than dropping a grand or two on amps and dacs (tubes not included).
I hope you realize that there's much more that goes into making these amps and DACs that small companies have to account for. You're not solely paying for the sound, that's not how the economics work.
@@djhmax09 As a consumer buying audio gear I am paying for sound quality. At best a small fraction for ergonomics. Since good sound quality and reliability is available is available easily from $10-30 then whatever the manufacturer wants to slap on their product needs further explanation as to why I ought to pay for it. I do have fancy dacs and amps, but they are horrific value as I said.
Sonic Edge said their primary benefit is that the bandwidth of the driver is proportionally tiny so you can make one kind of driver perform very well in its happiest little freq band. In terms of hearing damage, I'm not sure exactly what Cameron's concern is, but the ultrasonics are canceled (hence the power efficiency). Also, it does use MEMS, that's just not the headline.
I want to place a headphone on the market that uses plasma drivers. That’s the fastest response available and very dynamic. It will be closed back and virtually waterproof for outdoor use.
Great stream. Kuddos to GoldenSound on sticking to his guns that amps sound different and subtantiating it. Also agree with Blake on the idea that the community asks you to buy a $10k DAC or amp to properly achieve high quality audio. High quality audio certainly is not scaled up based on price. While the objective measurements can now be achieved with low cost parts, everything else is in the subjective space. But that said, now there's a counter-culture phenomena coming up, in ASR for example, to make a case against expensive gear certainly being worst than their cheaper counter part. Which can be just as biased and non-objective as well.
@222:22:22 Objectivity can only go so far, and some things simply can not be measured. Yes, absolutely there are certain "predictors", however in my experience they can be very misleading. Take the beyerdynamic T70. On paper they should put out some tight and prominent bass. In reality my old wired EarPods out performed the T70 in bass response, and by a huge margin at that. The T70 has the wimpiest bass I have heard in any headphones, no exaggeration. Speaking of beyerdynamic, I can't stand any of their headphones as I find them piercingly bright, yet at the same time I have never had a problem with any HiFiMAN headphones despite having similar treble response characteristics.
Nope, there are human-audible things that are simply not BEING measured YET, and there's no widespread understanding of how to interpret them even if we did find measurement results here and there. You can't support the opinion that there are human-audible things that physically CAN'T be measured, science doesn't back you up.
The headphone amps in my preamps I've owned or my receiver cannot come close to comparing to any of the Schiit I own. My best are the Asgard and the Vali, but the others are very good including both of the old Magni's. I have always want to own a piece of Mac and look at their $2500 Headphone amp, but doubt that is is $2k better.
Interesting topics but the hosts interrupt one another way too often which leads to a thrashy conversation and ultimately means that the hosts can't convey complex topics in a holistic manner
Yeah. The answer is most definitely yes. 3 hours talking about measurements, volume matching and other super subjective topics when anyone with a working set of ears can notice in 2mins that there is a difference.
@@kevintj604They can also tell the difference between normal and “oxygen-free” copper cables and other such nonsense. Placebo+confirmation bias is a powerful thing. That’s not to say that there are no differences between solid state amps- but to suggest that subjective experience somehow nullifies the need for scientific, objective inquiry is blatantly untrue as far as I’m concerned. Again- assuming we are talking about solid state amplifiers- tube amps are OBVIOUSLY an exception here- I have never seen (or heard) compelling evidence that different, transparent, solid state amplifiers of reasonable quality (JDS Atom, DX3, etc) are notably different from one another- beyond their ability or lack thereof to drive a specific set of headphones to the desired listening volume.
@@OneOddFellow Your first comment regarding cables is obviously meant to provoke a negative response from me so I’ll leave that aside and stick to the actual topic at hand. You’ve already mentioned that there obviously is a difference between tube and solid state. That difference is beyond easy to understand and noticeable within seconds of listening so that’s already one point in favor of the argument that there is a difference between amps. With that in mind there are also many different kinds of amp topology and I’ll use Questyle’s Current Mode or Zahl’s Class A for example’s. Both of these amps even volume matched sound absolutely nothing like a Topping D90 for example. The implementation of power delivery is totally different. If you introduce something like a Burson amp that uses swappable op-amps those will change the sound as well. I can give you examples all day long that prove that there is clearly a difference between amps. I haven’t even introduced DAC implementation and synergy into this mix yet and that’s even another rabbit hole that will change the sound. For the most part I agree that the vast majority of people should spend the majority of their budget on the transducer but to say that amps don’t make any difference and are all the same is blatantly false.
It can be audible, it can be measurable, but wether it sounds better depends on the target skull sponge. Soundstage is an artificial concept, except for acoustic, discrete recordings, where you could relate it to an actual live performance.
If we are talking soundblaster g6 yes if we are talking 1000 to 50000 dac amps no its all bullshit once tou hit a level of clear clean and true there is no higher level
it's very simple. not all headphone amps are equal. there are ones that will bring the most out of a headphone, and then there are other ones that will fail to reach those potentials. to some listeners, an amp can reach those potentials to an acceptable extent in relationship to its price.

"Do headphone amps REALLY matter?" Save yourself 3.5 hours, the answer is simple and it's in the affirmative. Anyone believing the opposite is contradicted by reality; a simple audition of two relatively different - in terms of audio quality - amps can demonstrate it.
Had a jds atom, sounded horrible, maybe they are better now idk but so far its been the worse sounding amp ive used that was long before I knew anything about audio

@@Tealc2323 this was the atom 1, like I said maybe it sounds better now, it worked, the rca cables worked, bought world best, and mono price ones, I used on 3 different dacs they all worked on other systems, I bought the atom brand new, it ran, it got plenty loud, you could hear the all the sound, but to me just sounded bad, but most stuff under $200 sounds bad to me, zen dac was just ok but it was kinda meh even with the i ipowerx supply also, but it was better then the atom maybe there stuff in those prices that are good now i dont know, maybe you need the atom dac with it couldnt tell ya, I tried the schitt fulla 4 that was even better but honestly still crappy sounding imo, all that cheap stuff to me sounds bad idk what it is, my lg v40. Jack sounds better
Imo amps (and dacs) only start to matter in the high end. Once one is spending multiple thousands on an amp (or dac), the experience can be quite insane. Everybody has to know for himself whether this absurd "price of entry" is worth this hobby. For cheaper units (still talking multiple hundreds) every transparent amp that can power the headphone will sound similar. Again, imo.
The price of entry can certainly be out there, but what most people don't realize is the economics of it all. You're not simply just paying for the sound quality alone.
The only jump that's real is porr internals vs good entry externals tne jump from phone laptop to souldblaster g6 is 100x the jump of a g6 to a k19 or 50k dreamworld unit.
much of what you guys are talking about is logical and provable, at least on the surface. then again, some of us verteran audiophiles can see and hear further through the mire. i once attended an audiophile society meeting an LA Audio in LA on Western avenue. in a top tier system, with Nordost cabling from the wall to the speakers via components connected with their interconnects from the same level, entry. we listened for about 30 minutes to varying music with CD as the source. then, intermission during which EVERY cable in the system was replaced with their highest level wiring.. the difference was unmistakeable. unfortunately there are no known reliable testing protocol for illustrating such differences. this leads to opaque advertising rhetoric. the Amazing Randi tests involving Michael Fremer were made into a farcical tapdance by Randi that exhausted MF's patience. try extended listening and also evaluate how the differences make you feel over time. there are NO absolutes here.

It's getting closer and closer. But higher the cost you start getting better quality materials.
Class K amplifiers are more simple that class A. However the frequency spectrum is nearly reduced to midrange.
i recently put 2" sorbothane 1/2 spheres under NAS so now I don't hear it running.
An advice to all those measuring amps and DACs: check Serge Smironff's df metric.
We need a snake oil tier list.....please......
There's no such thing as snake oil in the audiophile world.. they only have pure essential oils
Well saying an amp sounds better based on the topolgy IS snake oil because its not true just for that reason.
There really isnt a category of snake oil. Even cables can matter.
Plasma headphone drivers lend themselves to be easily configured into extremely accurate and traveling surround sound drivers also.
Volume level is a bit low. Needs to be louder by about 30%.
