@iopscrl ...Cary CAD 805 (there have been several versions of this classic design over the years). For some this is a benchmark Class A SET amp. Others believe it is not accurate to some degree. Listen and decide for yourself.
@iopscrl Speaking of 805s, Did you by chance listen to or review the newer 805RS version, and compare to anything?

After my Cary SLI-80 and Cary V12R (both heavily upgraded), I was not in a position to buy the 805RS (or the room) and landed on Quicksilver Mono 120s, now with upgrades, same caps and others as my former Cary amps had. Sound very nice now, plenty of drive with KT120s or KT150s. PP purpose built for KT150s. Big quality transformers, power caps, 600v plate voltage. Driving the tubes "in the window" as I know it now. And, tried a few DH custom Inspire amps between. Not enough drive for my larger custom speakers. Maybe going back to full triode though, with a little more power/drive, maybe. Thought you might know this looking at the collection of amps you’ve commented on here so far.
Since I still have and enjoy using my later my Cary SLP-98 preamp w/6SN7s, still kind of thinking about parting with the M120s down the road to help fund it some (deciding later this yer, not sure I will - can’t get them any more) yet possibly ordering the 805RS monos. 845s or 211s, not sure which. Damn things are 24" deep though. i.e. not referring to the older version 805s, just the new model, if you happen to know more. These -or- I may commission a good designer-builder to custom build some with some other (more available) opts, not 211s or 845s. Thx.
