The room is about 25 X 30-feet with 25-foot cathedral ceilings.
The equipment is 70's & 80's vintage Yamaha gear. CX-800 Preamp, B6 Power Amp, T80 Tuner, CDX-5000 CD Player & YP-D8 Turntable.
The Klipschorns fill the large space nicely. Since the mods, I have noticed a more clear & defined sound stage and very tight & improved bass response. I credit the pipe insulation for most of the bass improvement, a trick I learned on this forum by the way.
