Soix - good point about the L100s specs and performance. I was thinking the 88ia because when stereophile reviewed the L100s they concluded the Cary SLI80 HS in triode mode (40watts) bested two other amps. However, this is not expertise so I can't elaborate on the tube impact.
I have my eyes on a couple of used Cronus Magnums and will check out the Unison.
Thanks everyone.
