The system in use that day comprised:
Ayre DX-5-DSD Blu-ray player used as a transport
Ayre QX-5 Twenty DAC
Ayre KX-R Twenty preamplifier
Ayre MX-R Twenty monoblock amplifiers
TAD Ref One loudspeakers
All cables and interconnects (except between the transport and DAC) were Ayre Signature series made by Cardas to Ayre's specifications. All equipment was plugged into several Ayre L-5xe power conditioners. All AC receptacles were Hubbell hospital-grade. The equipment rack was an HRS (the all metal one that is one step down from their extremely expensive top-of-the-line). All components, cables, power cords, and interconnects were placed on myrtle wood blocks. The speakers were placed on stainless-steel cones I designed when I worked at Avalon.
The room itself has some fundamental flaws, as it is a commercial building with pre-cast concrete members. The members placed upright to create the walls have reinforcing ribs on the outside of the building, while the identical members used for the roof place the ribs on the inside of the building. This creates parallel structures about 2' tall every 4' and creates standing waves at about 160Hz. We have built a double layer sheetrock ceiling in the sound room to keep the bass from reaching the resonance-creating ribs another 8' higher, but enough energy leaks up there to excite the resonance and the bass response in the room is wildly uneven.
Like almost any room, a month or two of exposure allows the ear/brain to filter out the imperfections, as does more nearfield listening. Hope this helps.
