Aiyima’s new balanced amplifier- A20

brainwash dude
From your recent posts, I would be considering that you have been brainwashed by some kind of opamp rolling witch doctor. :P

Is there some kind of pagan ritual that goes with rolling opamps... some kind of sacrifice to the opamp Gods?

Well the opa828 has less influence over the tubes than the rest of the op amps I tested which is why I have great bass and why many people have recommended this chip for the T20, it gets out of the way of the tubes unlike the others which colour the tubes sound, each in a specific way.

The fact is the ‘op amp’ is not a done project and what people have suggested in regard to having no influence over the sound just is not true, but the opa828 has less influence than the others with the opa1656 being a close second.

What people are telling me an op amp is and should do if fine, I understand that but what they are doing in real time matters more and very very few actually are achieving that goal, so the dream is not yet a reality.

Thank you for your input it’s been helpful to understand to some degree at least what maybe some people may expect from their measurements but it seems to be a very different situation out side of what maybe the in house goal was to be. Man cannot design or make anything perfect in and of himself regardless of what he may believe. Only Jesus is perfect my friends.
Who can improve on what he has made, no one. Who can improve on what He has done at the cross, no one. Can you improve on a tree?

Who can improve on what an op amp may do, everyone!

No witchcraft involved, at least not intentionally on my side.

Have a great day!

lol….that is a brainwash dude.….you are at liberty to tell me to ‘fugger off’ if you wish but I think there something wrong there if you are taking that BBC clip seriously.
Regardless - no-one here is fooled by your commitment to your beliefs. We see it all the time - it is always wrong headed and ignorant - particularly so when people, such as yourself are not even interested in engaging with the science.

Obviously not witchcraft involved - nor is there any understanding of engineering - nor science, particularly psychoacoustics. Just "I can hear it - it must be true"

This is not a matter of understanding any of those things at this stage. Any understanding of that nature is only essential at the beginning. We are talking end results post engineering, post application of science and so called psychoacoustics of which the claims, as pompous as they are, have proved fallible. To say that and I quote “you can’t hear it - so it must be true….” Is merely a reflection of yourself. You accuse me of attempting to fool you, no that’s not true sir but your own foolery maybe exposed and why would that be a bad thing unless one wants remain in such.

I am not against knowledge when that knowledge is genuine. You believe in man made truth and inventors above all things it seems because in your own limited understanding it makes the most sense and yet for all of this you remain in pursuit of destruction of such and or others simultaneously and call it progress or in some cases science.
As I said earlier non of these things are finished projects or fallible proofs or have any power to dictate such. That much is obvious.

My advice as seen as you like to buy machines to prove your points or rely on them for giving you an opinion and purpose.
Buy a T20/A20 combo, stick the very well engineered opa828 and Muses 02 in them and enjoy! You may actually even hear why this post has been written.

As what this post is about is the desire as others have wished to support to some degree, to have an op amp that least influences the sound of the tubes in the T20 and to which that answer has been commonly found to be the opa828.
Cheers!

can’t hear it
We've all thought we heard differences between devices, even "night and day" differences... but when compared level matched and without peeking, it all goes away in the majority of cases.

I'm unsure how you do not then understand how it never existed at all and was simply the human brain playing its usual tricks on us. We're all subject to this, don't feel bad or take all this so personally.

Anyway, unless you have something solid to present, the discussion is becoming circular and a waste of members time replying to you.

I think it would be appreciated by many if you gave it a rest for now, as you've made your opinions quite clear and for now it seems you refuse to learn the facts.

Would you mind not cherry picking and at worse half of a comment then delivering it out of context. It also proves that the debate of arguments are lost on your side resorting to such tactics.
It’s a childish argument strategy that no one in their right mind wishes to entertain.

Members are not being forced to engage here but only invited to leave their experience or expertise depending.
As far as giving anything a rest I think that ought to on behalf of those whom berate and slander people for not agreeing with their preconceived ideas in the audio field.

It’s shows bad spirit, a closed mind and a draconian attitude.
You don’t understand how what never existed exactly? If you mean the momentum of post production results then they very much exist in every aspect of existence and how they perceived has a vast amount differences that simply far outweigh the proposition of one definitive outcome here. and if someone cannot appreciate what someone has found to be in existence and yet does not discover that for themselves does not mean it does not exist. This is how ridiculous your argument is; if someone speaks to you in one way but also in two ways meaning something else entry and you only hear one thing they said then you never heard them at all and that’s how you are coming across, deaf to what actually is really there because you take it at face value that is all there is through the assumption that someone else has proven it. That’s a sheeple mentality that lacks discernment.

This is not your or my post to either command whom takes part or govern peoples opinons. People have put their views forward and that’s fine so let us live and let live of which is the only way and history proves it for do you see a master race? In truth there is a Masters race in fact two and one of them will not live and let live.

So please take your own advice and allow people to express their experiences regardless without casting them off as idiots.

With respect level matching etc has been done and nothing went away in regard to actual outcome of which has been given here in this post as the most appropriate piece of engineering for the purpose required.
Excuse me if I am wrong but I thought that what it was all about.
The optimal product was not sold as it now is here as result of the test for reasons more commonly found in economics and not measured testing.

So thank you Mr J Smith but now these improvements have been found through better engineering my system and now sounds pucka!

Cheers and have a cracking day sir!

Apologies if you feel this way... but I'm unsure what you didn't get when I said;

I'm starting to think you're not posting here in good faith. You've been a member for some time, so I'm sure you understand the reason for and direction of this forum.

How about no? ASR is not a forum for "but I hear it" subjectivist nonsense, there are countless places where this flavor of drivel would be warmly received. If you've actually had any meaningful experience doing properly controlled listening tests, you would know that none of the unevidenced claims you've made are the slightest bit useful or meaningful without being validated by such a test, and I'm going to call it out as what it is: complete nonsense.

Also, as you clearly lack basic understanding of the technical topic you're talking about, perhaps refrain from pontificating about "limits of human knowledge" you are not equipped to evaluate.

This.
 
I find the “Ignore” feature of this forum to be helpful. For any post, just select the photo of the poster and choose the “Ignore” option so that you won’t see any more posts from that user.

I’ve been ignoring @Schlippwhip68 for some time. Serenity now!
 
Anyway, I hope to see a the review for this device here soon. I am kinda sorta interested in this, but I don't want to take a risk, and find out later that it doesn't perform as well as the 3e A7 I have right now.

My 2 cents…..
I think it’s pretty safe to say that 3e A7 is pretty much unbeatable just for pure measured parameters or performance.
A20 has several additional features in comparison which are really useful, I would take A20’s measurements around their A70’s which is surely a win.

PE. I am saying all this as I have both in action in my listening room.

Results similar to the A70 is sort of what I am expecting to see, and partially the source of my reservations towards getting this without first seeing the objective data. If there are no concerns with load dependency, and distortion, I may just be sold on this unit.

I do want to see measurements, but we don't know when that's are going to happen.

I'm sure the review backlog is quite large!

Thankfully I'm not exactly chomping at the bit to replace anything right now, this is more of a curiosity than anything else because it's new, and shiny.

Apologies accepted.

No such thing as “don’t take this personally,” what other person are you taking to?
Anyways let’s move on.

How about no.
I wonder, could you provide your qualifications for everyone to see, I am sure you’re very proud. Although it’s not going to influence my own personal decision whether you do or don’t to be honest as I will tune my audio much like Harmon Kardon, to my own ear.
What ever the argument maybe, most people are always going to go with their ear and have already realised that great measurements do not mean great sound quality! They will more than likely return something that sounds bad although has great measurements than something that sounds great but doesn’t have great measurements so at the end of the day, the ears have it and with that I harmlessly, without any malice, or intention of personal gain, added my own experiences as to what my own ear preferred as many others have here.

This was not a post concerning measurement or engineering primarily for me although with the subject of choosing an op amp these things are to be digested, which they have and recommendations including that of sound quality have been volunteered which I am sure many will appreciate given an common ground. If my post is such a problem for you then you are free to employ the ignore button, the choice is yours but it does seem that is a little out of reach presently, who knows, maybe down to the dogmatic approach you are currently displaying.

I think maybe you would be better suited to Amirns review post than this one to be honest.

Thanks now and have a great day.

It simple - if you swap an op amp and you can hear a real difference that doesn't come from perceptive bias - it is not working properly, and you have dramaticallly worsened performance.

As tempting as it is, politely ignoring this sort of inanity is how audio communities turn into cesspits of golden-eared $3000 USB cable cork-sniffers, and I would hate to see ASR turn into that.
Op-amps are not "bold", "musical", "detailed", "reserved", "bloated" etc. This is just fundamentally nonsensical (even if we neglect the quite ludicrous idea that a linear device more-or-less doing its job can create complex perceptual effects, as opposed to the mundanity of distortion and noise) - we can grant an op-amp *might* have (non-illusory) audible effects if you put them in a slot where it starts to oscillate or have exorbitant amounts of distortion or otherwise misbehave (which is hardly unlikely when people mindlessly swap circuit components), but this is not intrinsic to the op-amp, it is always a matter of what the op-amp is doing in the circuit.
