I only owned the Joule LA150 MKII and then the LA150
Signature preamps which I used at various times with the
amps listed in my OP.
While I certainly enjoyed the Joule mono-blocks at shows, I
would say no better than the Atma-sphere M60s which were
also more affordable - I now use an Atma preamp with them. I
went back and forth with the Lightspeed Attenuator and the
Joule preamp with my Music Reference RM10 MKIIs and loved
both combos, so I sold the $7000 Joule and kept the $450
LSA.
If I bought an SS amp I suspect the LSA would not work right
because of impedance problems in most cases, and I would
probably feel the need for tubes somewhere in the chain.
