I have a tube amp with my Orpheus Aurora 3s - purely for 2 channell audio and absolutely love it - particularly with the vocals or anything classical really.

I haven't hooked up my axioms (M22s) to the cayin, purely because they're in another room and I bought them for the HT room and the occasional musical theatrics.

For anyone who is seriously into classical sounds, I would suggest taking at look at the tube amps. It sure opened up my ears. It wouldn't be for everyone, admittedly.

Now this is how you learn Philosophy :
