The audio equipment has a separate 240VAC mains spur, run straight from the fuse box to behind the equipment rack (a distance of about 12m). Conductors in the spur cable are 6mm2(~9AWG).
Two Furutech FP-15A-Cu AC duplex outlets are mounted into a fire and acoustic rated wall-box. At the wall socket an Audience aR2p-TO, Teflon capped line power conditioner (240V version) is used. Two VH Audio Hotbox's with Furutech FI-11Cu male wall plug and FP-15Cu outlets are plugged into the aR2p-TO.
Power cords are all DIY. Bob Crump's 'Asylum' recipe for the turntable/SDS, Chris VH's DIY Flavor 2 design on the pre/power amps and VH Audio Flavor 3 on the digital sources. The DIY F2/F3s can be used with many different connectors available from Chris' parts list. I chose the Furutech FI-11Ag IECs and the FI-11Cu male plugs.
All power cords have been made a similar length to help maintain a star earthing scheme.
The room size had to fit basic design constraints - odd shapes would be difficult to analyse and expensive to build, so basic rectangular construction was chosen. Dimensions are: 6m length, 4.3m width and 2.7m height. The dimensions of the room started by following Sepmeyer's 1 : 1.6 : 2.33 ratios and was slightly adjusted using basic (calculated) spectrum analysis of room modes.
Each of the front corners behind the speakers have 4 stacked Vicoustic Super bass traps and there are Vicoustic Vicpattern Ultra and DC2 diffuser panels on the front wall each side of the window. Vicoustic Wavewood 1.2m panels are mounted vertically at the first reflection points of the speakers with some more 1.2m Wavewood panels mounted horizontally along the side walls. DC2 diffusers are mounted above the Wavewood panels and more of the DC2 panels on the rear wall above the record shelving. Two groups of four DC2 diffusers are attached to the ceiling at the first reflection points between the speakers and the listening position.
Speakers are positioned with centre of the front baffles about 1.9m from the front wall and about 800mm from the side walls. Speakers are placed as symmetrically as possible (measured and matched from walls). The listening position is 2m from the rear wall. This (approximately) forms a nearfield 2.5m equilateral listening triangle between speakers and listening position.
The speakers are placed on Townshend Isolation Podiums, which use adjustable spring pods to isolate the speakers from the floor.
Its amazing how focussed and precise the soundfield of a big baffled speaker like the SCM100 can be when set up in this manner. The superb clarity and neutrality of the SCM100 is exploited and provides great insight into recordings.
