Establishing a common analog listening bias

Dear friends: I just have a very good experience that confirm the necessity to have this " common ground " by ourself.

Making a small change in our tonearm design I test the " old " prototype against the " new " with that small change on it. As always I made it with my " common ground " recordings/tracks, the change was so " tiny " that after the Janis Ian recordings everything the same ( at least I can't detect differences in the performance. ) but when I run the Eagles one at the very first stroke on the percussion the " difference " comes alive, I run the Patricia Barber where there were almost no diffrence.

I'm talking here of very tiny changes that fortunately for me I can dettect through that " common ground " recordings. It is not only to have a high resolution audio system with a near perfect set up but to have the software and to know what looking for.

Regards and enjoy the music,
Raul.

Not so easy is it?

:-))))

No certainly not easy - 10 audiophiles = 11 opinions.
Guess we have to abandon the idea of establishing any common ground regarding a set/list of "evaluation records" for high-end audio purpose.
But then that idea is failing in almost all areas of social/public life today.
How could I dare hoping for any better here....(:^) ....
Alas - it was a try.
Cheers,
