Hidden Gems in Pre-Owned Solid State Power Amplifiers?

I've a nicely detailed area with inefficient vintage Infinity inc. IRS Beta.
Tried several styles, ended up with more heavy vintage gear in the form of Yamaha Pc4002m's and Pc5002m. Set up so I don't have to move them ouch... I'm hearing the cleanest most powerful,forward,soundstage yet. 

I have a YBA 3 dual transformer amp with Vandersteen 2 speakers. I heard it and stopped looking for better. It's a great fit with Vandersteens, it doesn't peel paint but it doesn't need to.

Fortunately for me, there were several amps that had a special sound and did not break the bank. One of the used pieces that became a favorite was a Forte' model 3. As luck would have it there was a defective chip that started to produce trouble and the amp had to be abandoned. I am having it rebuilt as I write this, but it will not be the same amp, that is for sure. A few changes are being made and I am hoping for the best.

For the flexible possibilities imparted by his design and the extraordinary sound quality my Sansui AU 7700 is the amplifier to die for, especially at low price...No modern amplifier is so flexible and you must pay way over 1000 bucks to beat his organic and balanced tube like musicality and S.S. accuracy... A legend that does not lie...
