If if you can find a threshold S/500 is a great option even when is from the 80’s it is a great sounding amp. 
Levinson 23.5I use the amp to power Tympani 1-D's.Previously, I listened to a JBL Hartsfield / Marantz 8b combo daily for years.  When I purchased the 23.5, I swapped it for the 8b and was shocked to hear that it was just as warm and musical, but had even more bass control.  I've owned the 23.5 twice now... I lust for 20.6's!
I’ve had Krell KMA-160’s and Pass 250’s (I think those were the ones) and now have Krell EV 600’s.  The 160’s was my first experience with pure class A bias amps.  I .loved them, but just didn’t have enough power.  I was pushing Martin Logan Monoliths and wanted to get a beefy tube amp for the screens, but ended up selling the speakers here on Agon.  I bought a couple of demo Max II’s and used the Pass Labs for them, but ran into the same problem.  Thought about going to tubes, but learned they would be too much $$, for the power I wanted.  With the EV-600’s, I can find no fault.  I’ve never seen a review of them here and bought them used from a fellow Agoner and love them.  To me, there’s nothing like a class A amp.
