Hi Frank, and firstly thanks for trying these out. And there is no rush. Take your time

I'm not going to prompt on this one other than to say trust what you hear, and from your comment it seems you are hearing "something".

I'm really looking forward to see how this one pans out

Hi Karl,
I gave it a very, very short try. My flat is being reconstructed. So I have only ONE speaker in my small office. The floor-standing speaker stands 50 cm from my left ear, but is driven with my hi-end preamp and power amplifier . I am listening to left channel only. This is my result, 1st take, no repetitions, no re-tries.

No, do not do it. There would be a change in LF step and phase response. In amplitude response as well, but not that much pronounced.

Hi Pavel, so your final answer then, you still have phone a friend or ask the audience

Firstly and seriously though, thanks for taking part, and I must say that is a mighty impressive ABX result... but what we would really need to do now is follow that through and see if the audible differences you hear are as easy to pick out in the random files. It is on that result where a test such as this "stands or falls".

Great result though. I hope that encourages others to give this a try.

Hi Karl, unfortunately I have no chance to test a dozen of files now.
Anyway, your A and B test files are very well matched, as shown in the attachments. I believe even SY would not have his usual objections .
Thanks again for a great test.

Looks like pointless, though.

Actually, I think Mooly did a very nice job here. I haven't looked at the files yet, but the test structure is excellent.

I've just had a listen with my cheap logitech usb headphones on my laptop (which are the best I have), and I definitely at this stage wouldn't try an ABX with foobar because I can't pick up on anything that I could use as a differentiator. I might try with a different set of (equally cheap) analogue headphones with my focusrite 2i2 and see if that makes any difference

I have not concentrated on any detail. Just the overall tonality of the introductory bow part, that was all. But I have not tried headphones, I have one of my Quadral floor standing speakers 50cm next to my left ear

On Stax ES phones, I hear the same.
Ditto the opamp comparison.
