I had CLS 11,Sequel, Quad 63, stacked 57's and now Acoustat monitor X(includes the tube servo amps).
The stacked 57's were very nice.The xtra panel doesn't give more bass, as in going lower to 20hz.
It just fills more of the room up with the bass that it can deliver,so you do feel like you are getting more bass, just not deeper bass.I wired the panels so they stayed at 15-16 ohms.
I drove the stacked 57's with an AtmaSphere s30.
Very nice,and not much chance of overdriving the panels.
I also used an old 1960's tube integrated from Bell,using 6V6 power tubes.
Those 18 tube watts off the 16 ohm transformer were really something also.
One of my audio friends commented that this system "drew you into the music"
I have a friend who has the SoundLab Ultimate Ones driven by a pair of CAT amps, also tubes.
This system is one of the best I have ever heard.
But ,not everyone can afford the Ones and the kind of amplification they need.
I was very fortunate to acquire the Acoustat's ,got the amps modded and I feel I have ended my journey.
I have no regrets in selling any of my other systems.
