The room is long 33 feet and I listen across the 16 foot side. Front wall is full of mounted African animals. Right side is all glass, two 7 foot windows and a sliding door. YUCK.
The Grimm MU1 and the Lampizator Horizon 360 are producing a dream digital sound. I had the full Vivaldi stack and it was too flat and analytical for my tastes. The Accuphase A300s were also hard won after a Krell KSA 150 to a Naim DR NAP 300 to Parasound JC1+ to M900u Luxman to ARC 160Ms. to an Gryphon Antileon EVO to the Accuphase. The two Tube traps on the front wall made a huge improvement in imaging and timbre. Way more contribution than the $1600 cost. The three 6 inch thick 2 by 4 foot GIK panels on the rear wall seemed to make no sonic contribution, but they look good. The Rockport Cygnus have a sound that is both extremely resolving, yet with no harshness that used to be the price paid for resolution. These speakers are highly recommended.
