Hidden Gems in Pre-Owned Solid State Power Amplifiers?


Browse the listings for power amplifiers (e.g. under $5K) and you notice a myriad of Classe, Parasound, Bryston, older McIntosh and Mark Levinson and lots of Pass Labs.
So many in fact that you wonder why.
What are the true audiophile gems in the pre-owned solid state market? Thanks in advance.

Yamaha MX-1 and MX-2 Power amps.  They perform flawlessly down to a speaker impedance of 2 ohms and came out at the peak of 2-channel stereo era before everyone started to make surround sound integrated amps. 
I also own a Kinergetics KBA-75 class A amp.  It was excellent back in the day but needs to have upgrades to compete now.  The HK 16 is an excellent power amp especially for the used prices but the XX model is in another league altogether.  If I was to buy a SS power amp today, that is what I would buy as a SS power amp in total stock form.

Most people here know that I build audio components - the final versions of my hybrid power amp will be out soon.  These are point-to-point wired, V-Capacitors, Amtrans, Shinkoh and Caddock resistors, Plitron Transformer & toroidal choke.  If you are looking to hear something special, contact me.  Yeah I know I snuck that one in!

Happy Listening.
