Solid State Amps for Quad ESL 57?

Hello to all Quad lovers! :)
I'm running stacked 57' with JAS super tweeters and with Audio Aero Prestige mono's, in parallel.
Also 2 MJ Acoustics Ref.1 subs with modded cabinet.
Quads were 100% rebuild by Kent and each speaker has Valhalla shotgun speaker cable.
I built the frame from the scratch (not using the original frames) and as much as I wanted to make life easier for myself and have them in the strait line, I always liked when each pair can be tilted separately, facing my ear level. Frame is from maple-ebony real wood and it weights over 200lbs and with adjustable tilt.
Bottom pair is in the similar tilt and position like would be on the original legs and the top pair are tilted downward a bit.
Probably most will not agree with this setup, by this way I got the best detail and transparency and suits my taste.

I'm very, very happy with the sound, but I'm tired of searching for tubes!
I'm looking to  replace my amps with SS. I'm thinking two stereo SS's on each side, one speaker per channel.
The only problem is finding those SS amp's and at reasonable cost! :)

Best,
Adam

If a pair of low-watt Pass amps are too rich for your blood, the old Bedini 25/25 is considered one of the all-time best ss amps for the Quad. They show up from time to time, the last one I saw selling for $795 here on Audiogon.

If you haven't done so already I highly recommend removing the metal screens. It's shocking how much of a (negative) impact the screens make.

I don’t have the screens since I build different, much sturdier and heavier frames.
Also removed the felt form the bass panels.

Adam, your stacked Quad frames look amazing.
