MC 275 tube amps with what speakers ?

For over 20 years I ran a pair of Mac MC 275 Gordon Gow Commemorative Edition amps strapped in mono into a pair of Martin-Logan Quests, a hybrid electrostatic with a 48” x 18” ‘stat panel and a 12” woofer in a sealed enclosure.  Room was 16’ x 22’ with a vaulted ceiling.  No problem whatsoever ever in driving that difficult load and the sound was glorious.  FWIW,  I was only on my second set of output tubes when I moved and sold the system, and they still met spec.

I have recently been introduced to Odeon Speakers. The experiencing them in a Room Dimension approx' 18' x 27' powered by EAR Power Amplification has been something special.

These are proving themselves as very attractive alternative Speakers to the resident Quad ESL 2912.

I checked the Opera Home Site and a USA Dealer is:

JBL 4367 are just above your budget. JBL and McIntosh tube amps have a long tradition of working well together.
