I've noticed a few of your posts "The 3000anvs are easy to drive", as well as this one.
I've always felt the Th900s were more musical than the 3000anvs, at least till I found the right amp pairing for it. I don't
actually think the 3000anvs are easy to drive (optimally).
They play out of anything, but are very amp dependent. It seems like hybrid tube amps do well with it, like the Svetlana
and the Eddie Currants/ Elekits.
At this point, for personal preference, on this setup, I rate the 3000anvs significantly higher than the TH900s - mainly
because of it's musical mids vs what seems to be recessed mids on the TH900s.
I somehow think the TH900s sound great on most amos.
