Atma-Sphere Class D… Amazing

Of course, if you do listening tests with total prejudice then you will never hear anything.

True, as is the converse, which you are living proof of: if you do listening tests with total prejudice then you will hear everything. 

Who are you to say what I have and haven't tried, tested, and listened to? You haven't a clue.

Plenty of people have tried a lot of goofy things- some swear they hear a difference, others swear they can't. This isn't proof positive that what you claim is "truth" in a real, objective way. There have been plenty of bona fide scientific tests of cables, etc., etc., and most results show no differences. Of course then people like you like to jump in with "you aren't measuring the right things!" or "it can't be measured!". What if the differences are actually not in the article being tested but in the listener's head? The simplest explanation is usually the correct one and when modern science which can measure just about anything to levels beyond human cognizance, the far more likely explanation to why some people can hear a difference and others can't is simply that perceptions differ between people. There are a list of reasons why this can be that have been rigorously tested. All you offer is "trust me, it's TRUE"! Sorry, that's religion, and I don't need a profiteering guru to tell me what I can and can't hear.

The tweaks I suggest are universal.....every amp in every price category would improve it's sound to the same degree (assuming they are made like the Atmas). this includes the op amps......it does not matter how much feedback or how much gain is being used.....the sonic signature remains.......this will always be so.....everything has a sound.

The speaker cable plastic clampy thang is not dangerous.....you can mount the plastic hardware on something and no metal is exposed. I’ve always liked Goofy.....one of my favs. Check out the speaker ideas page on my website and you will see some plastic speaker wire clamps mounted on an external xover. Perfectly safe.

What Ralph believes is what he believes......only truth is truth.....you have to listen to know what is true in audio.......What you believe is what you believe......it is best to BE LIVE.......and that means LISTEN......then you will KNOW.

Shall we get back to listening impressions of the amp?

Will anyone try the steel removal and let us know? Be bold.....go where no one else would go.....do it for the gipper or your mother, or God or for YOU.

BE, LIVE, LISTEN, KNOW......and while you are at it....LOVE and JOY!

What little credibility you might have once had is now gone. You have basically just said Ralph doesn't know what he's talking about when it comes to op amps in his own design. You've never heard it and yet you imply that he didn't hear what he heard after YEARS of development on the product.

I predict you will delete your posts in this thread OR you are so falsely arrogant about what you think you know that you will double down. #zerocredibility

People believe and say and do all kinds of things......does not make it true.....same for me. What I state about op amps is my experience.....if Ralph has a different EXPERIENCE then that is fine. The only way to know what is true in this case is to try a discrete op amp in place of the one he uses and listen. I am not doing that....are you? So, neither of us knows what would happen......but since my experience has been universal (that is, no matter where and how you use an op amp......it has a sonic signature)......I bet it would be the same here.

This is what Ralph stated: "Our input buffer has a gain of 2, which is to say there’s a lot of feedback and with modern opamps, as long as you don’t ask more than about 20dB or so, they will be as neutral as you can get."

The above statement is not my experience......again, no matter how much feedback...all op amps sound different (and none of them are neutral)....all of them: discrete and Integrated circuit ones.

BTW, Nord, Apollon, VTV, etc. sell amps that have discrete input buffer option....so you can roll op amps......all op amp options sound different from each other.....this buffer is on the input of a class D Purifi module......it uses very little gain.....just like Ralph......you can also put adapter boards in these discrete op amp input boards with regular op amps on them.....yes, they sound different again....and not as good as the discrete ones.....go read their sites......email them....they will tell you about how different they sound......I am not the only one in the world with this experience.....lots and lots of people have rolled the latest op amps.......

Shall we move on? Or shall we keep talking about things that we cannot prove?

The tweaks I suggest are universal.....every amp in every price category would improve it's sound to the same degree ....everything has a sound.

One hand clapping...

The guru's credo: "everything has a sound and I can hear everything...just trust me..."

#zerocredibility indeed....
