Best amplifier for CLX

For your type of music and room size you may want to consider using subs. Most of the people I know with CLS's use them.

"I have tried most SS but not being really satisfied"

That could mean many different things. What is it that you are missing?

Hi Andrew,
Agree that to optimize full range ESL best is still to use high power tube amps..
Back in '80s, was pretty pleased driving my CLSsI & II with VTL300+Ultimate and/or
ARC Classic150+SP11. A buddy now has CLX augmented by a pair of Descent subs,
similarly, he too could not be fully satisfied by just about any SS amps he tried them
with--always finding the resultant a tad lean-ish--perhaps an inherent character of
CLXs?

Soulution700 is one SS which will control panels of your CLXs with an iron grip,
energizing to make them fuller sounding no doubt. But IMO, the Accuphase A200 is
timbre-ly more refined, pure and natural--not quite as obviously powerful in the bass,
but more articulate and goes just as deep, or almost compared to 700, but is deeper
than that of the stereo 710.

Since you currently already own an almost full Accuphase system, why not top it off
with A200 which will probably make best synergy? If thinking tube route, I'd look into
something like the Jadis which is largely known for its brute power, finesse whilst
being fuller sounding than most. Perhaps big VTL Siegfred or ARC Ref750 could make
good candidates as well, but too much heat and tubes, IMO.. ;)

Also for your room size, you probably do need a pair of Descent subs to aid pressurize room and give proper foundations to most music. This will also help in making the sound fuller, as well denser.

Yum these will drive the 1ohm loads of the CLX's nicely, just looked at these doubling wattage for each halving of impedance even down to 2ohm, means good current drive.
At idle consumes 200w each, means a good amount of Class A bias.
96kg each, has the power supply to back up the current it gives.
The only thing I don't like is the 3.7kohm input impedance, means it should be used with ss pre's only that have at a guess no more than 50ohm output impedance, eg: Krells or probably their own.
Or better still driven direct by a CDP or DAC with <50ohms output impedance that has volume controlability and forget about the preamps, as it is just 1.5v sensitivity for full output, and all CDP/DAC are over 2v these days.

Cheers George

Thanks
I should have mentioned I have the descent sub
My issue with solid state has been they seem go give the music
Especially strings and piano a "glare"
Also they are flat in sound state in comparison with bloom and micro I get
Even with cheap valve amps
Valves give more real sound stage also
I briefly had VAC amps and they were amazing
