Thank you for your answers,
I listened today a totally different system composed with a EAR 534 + 834 pre & amp and BW 805 signature speakers.
I found that voices (opera) and violin had a great texture, full of harmonics. The sound was neutral, with strong but not-firm bass.
These are perhaps the characteristics of tubes.
I find also that my system has some other qualities that I can now perhaps qualify with PRaT (that improves again with espek & 2250 !).
If Audio Research gives the quality of EAR harmonics with the minimum PRaT I have in mine, I am interested !
I plan a direct comparison in January between the two configurations. I will post the results.
