Quad ESL-63 and low-powered amps; Sun Audio, Atma


Looking for opinions about suitability of low-powered amps with my 63's. I currently have an Audio Note M3 pre, CJ MV-60 amp. Importantly, I cross the Quads at line level at 100 hz, first order with nice Vandersteen MH-5 crossovers to Vandy 2wq subs. So the main amp is relieved of much work below 50 hz or so.

Specifically, I am looking at Atma-sphere s-30 MkII OTL 30 watt amp, and possibly even a Sun Audio 2a3 SET 3 watt amp.

Given my crossover, does this lighten the load (power or impedance) in such a way that these amps would work fine? I imagine the Atma will have no issues, but what about the Sun?

Finally, I would love to hear any opinions about the relative sonic characteristics I might hear between the CJ, Atma and Sun. I listen to 50% acoustic jazz, 25% classical, 25% rock. 60% on vinyl... SOTA w/Grace 714 and Grado Ref Sonata1. CD is CEC transport to Audio Note 3.1 Signature. I value musicality and rich midrange over endless detail and "neutrality".

Thanks all.

Isn't this incredible that regardless of the topic or the thread wherein, our self proclaimed know all sucks you into this absurdly ridiculous, and exceedingly mundane, discussion of,... well, I'm in a loss of words in even how to characterize it. There's always an excuse and explanation instead of accepting the change in position which should be normal as we learn and grow.

Well, my friend willemj, with all due respect, I will be filtering your responses going forward. Not that I'm sure you care but just a little humility and acknowledgement of ones poor judgment can go a long way. Responding to your arguments is a colossal waste of time.
