Hi Peter,
Overture had the Esoteric Grandioso system on the M6’s. K1 Player/G1 Clock, preamp and monoblocks. It was set up in their high-end room, approximately 30 x 20 feet with a high ceiling. Many tube traps and some other acoustic treatments in the room.

I haven’t been there in years but , I know the room.
I also had a very impressive demo of the Avalon Saga w/Spectral in that room. When Overture was an Avalon and Spectral dealer.
