You should use very good speaker (low distortion speaker).
Many DIY'ers who built many amplifiers do not have good speaker. They think all amplifier sound same 😀
I agree with you and JC. The best is using no capacitor if possible.
+1. Decent with the best quality / price.
This said, I was totally astonished to read, about me, under the pen of Scott, that I thought someone serious:
"You guys never change your story, post some measurements of pathologically bad capacitors to sell $400 teflon caps vs COG or MKP for a few $."
Here he goes up in the pulpit, takes the head of the herd of believers, creates false rumors about those he got into the idea of fighting and calls them both morons, dishonest and infidels.
"When you want to kill your dog, you say he has rabies."
I am deeply disappointed. As I am when i read some of his aggressive and unfair answers to some contributors.
It's a phenomenon that is spreading on social networks, but I thought it was the prerogative of weak minds and uneducated people.
It all about EGO. Because they do not want other people better. Better at hearing threshold, better at recognize audio pattern (to hear the difference), better at equipment, etc.
Oh, adding 2 emoticons is a way to make a poor joke funny ?
It didn't make me laugh, as did the attempt to make-me look like a frustrated bad fu..ed. Sandbox.
Even making a joke has turned into a willy waving contest here now? I could say that if you thought it was a bad joke that would make you stupid or ignorant but I won't because that would probably make me look stupid or ignorant in the eyes of someone else with a bigger willy 🙄
Jakob,
As much as I appreciate your attempts to get something on the move, I must absolutely reject this generalisation.
On one hand, the correlation between measured numbers and audible differences is not very tight.
Compare Loudspeakers, Valve Amps and LP's, having distortions in the percentage range but potentially very agreable to audition, to solid state amplifiers with distortion figures in the ppm range.
Nevertheless we may hear differences between solid state amps with these low distortion figures played over speakers with a factor of a million more distortion.
Several sorts of distortions can help us to find construction errors or whatever, but they cover only part of the story.
So telling that a CD is better than an LP because the distortion is much lower is crap.
There is more between heaven and earth than just measured figures and we all know that.
So when someone hears some difference that cannot (yet) be measured, is no reason to immediately reject the possibility.
But when it starts bordering to "very unlikely" like hearing the difference between 44.1/16 and 96/24, one should be extremely careful not to jump to conclusions.
I don't want to exclude the possibility, but the least that has to be done is to set up a really valid experiment that can also be repeated and confirmed by others.
So having an open mind, yes absolutely, that's the reason for being on this Audio forum, but as a general rule, don't simply believe everything and stay critical.

@Scott,
Could you please make the cymbal file available that you used to subtract envelopes before and after BW restriction.
I would like to use it for some further experimenting, thereby using your results as a reference.

We are not defending it on sound quality grounds just on how dare you tell us how to spend our leisure time.
JC brings that upon himself with his support of Flooby dust and claiming he is superior to everyone else because he has won awards in audio mags.
My preferences are exactly that. No extraordinary claims. When extraordinary claims are made they are called out.
Most of us agree.
And I was teasing you. it worked
try hanging out in the analog source forum. There are those who honestly believe vinyl is superior and will hear no counter argument. It's easiest to just ignore them as there is no reasoning. As long as they are happy and don't try and force their beliefs down my throat all is good.
It probably would not help as much as you might expect. If have not done a lot of critical listening to dacs, there is no way you could imagine what I mean.
Say, for example, if said a change reduced a sound characteristic I associate with non-deterministic clock jitter artifacts, what would that mean to you in any practical sense? Little or nothing, and it would cause the boo-ing section to boo, "Impossible!" or, "something is terribly wrong with your dac, no decent dac has audible jitter!," because they don't know either.
It makes more sense to me to simply call it better. Less further problems created with the crazys that way.

It would mean that Markw4 claims he can discriminate by hearing between deterministic and Gaussian distributed jitter. I would instantly ask for proof, or else call yet another BS 😀.
Power supply noise effects on jitter might be audible?
Hence all the hullabaloo on upgrading psu.

I'd say if you haven't measured it then you are pulling reasons for the change out a cocked hat. Otherwise it's just another case of glomming for victory akin to random cap swaps and opamp rolling. If you posted before and after graphs with your impressions that would be progress.
That's a tough one. It would be tough even if you were here to listen. Much easier if I show you by switching clocks with a jumper and letting you listen to the difference. Once you get an idea of how two well known high performance audio clocks (right next to each other, both powered by the same super regulator) affect the sound of reproduced audio, then maybe I could start to describe what about that difference to listen for.
