Isis is truly SOTA loudspeaker. I like it a lot. Interesting enough I found solid-state amps to be better match with Isis then most tube amps(for example ARC REF210 did not sound right on Isis). CAT that Strapper211 use are probably best push-pull tube amps on the market with excellent bass(and Isis IMHO likes some control down there). Amps for Isis? Think Hovland Stratos/HP200 combo or something from Gryphon or Vitus... Pass X.5 or XA.5 could work as well...
BTW, I auditioned two loudspeakers that are better then Isis(to my ears) but, they also cost more...
