Perhaps its my pair of Beethovens you bougth? I sold my set and since that it has changed owner 3 times I think.
I and my Audiophile Buddies have a lot of experince with the Beethoven, A wonderful speaker but SO very difficult to match with the right amp. It also so critical to set up.
I tried the Rowland 8HC/Roewland 2 BUT it was not the best match.
Big Halcro also failed.
On the cheap 2 used Classe 300 stereo amps was good.
The best result was with Krell 450mcx on the top and a Krell
KSA 300 on the subs. That combo could really sing!
