The house is a ‘58 model that I bought in 1980. We finished its first remodeling in the spring of 1982. This room used to be the 14’ (4.23m)-wide living room. After pushing out its north (concrete-block, outside) wall five feet (1.5m.), it’s now 21’ (6.4m) wide and 19’ (5.8m.) deep. I also removed the ceiling and ‘moved it’ to the bottom of the roof which now slopes upward from 6.5’ (1.98m.) high at the front wall to about 12’ (3.66m.) at its peak over the listening position and then back down to meet the rear wall at the traditional 8’ (2.46m.) high. The room has a relatively low amount of parallel surfaces, and there’s only one 90-degree corner in the place (other than the walls’ intersections with the floor and ceiling). It has always sounded quite good, and after adding two HUGE basstraps, one corner of which is visible in the upper-left of the pic and the other of which lives at the intersection of the rear wall and the sloping ceiling, the c. 30Hz bass node is at least lower in level if not ‘tamed’. More on that later.
The system has evolved the last six months into more of a movie system–the years-old screen is in Panavision’s 2.35-ratio and is 96" wide–but it still plays two- and multichannel music excellently. Projector is an Epson pseudo-4K/3840 model ‘5040, and BrD and UHD discs look excellent at my 10-1/2’ (3.2m.) viewing distance.
Frontend is an Oppo '203 DP that’s HDMI-cabled to the new-late-last-year Marantz AV7704 preamp/processor. That drives the four visible poweramps and two Rythmik F15HP subwoofers located against the back (not front) wall. IC for the stereo channels is the EXCELLENT Neotec NEI-1002 solid-UPOCC-silver cable which is, as I write, being converted into balanced configuration using Neotec '6613 connectors. These will drive a pair of BHK 300s driving the Vienna Acoustics Mahlers. Current main amps are five-channel Butler TDB 5150s, one of which also drives a pair of ceiling Atmos/DTS:X speakers. Centerchannel is a Revel C208 driven, biwired, by a Stellar M700 (which sounds QUITE nice). Front-three speakercable is Clear Day solid-24g.-silver-conductor Double-Shotgun-Plus, the ‘Plus’ meaning each pole uses 6 conductors for c. 16-1/4g. per pole. The basscables are inexpensive stranded-copper 16g.-times-4, using 6 of those 16g. conductors per pole (= c. 8-1/4g.) for the mains and four conductors (= 10g.) for the CC.
Surrounds and ceilings in this 7.2.4 system are all ELAC B6s; I plan to further complicate the system by adding another pair of ceiling speakers for 7.2.6. Poweramps for the surrounds and ceilings are one of the Butlers (two channels) and a humble, old, EXCELLENT-for-the-purpose Outlaw 7100. After I replace the Butlers’ 10 channels with 2 from the '300s, I’ll find another inexpensive seven-channel amp to drive the 10 surrounds/ceilings.
The Rythmik SWs are driven in stereo by the front-L/R channels–NOT the ‘.1’ channel–and sound excellent.
Power conditioner is a Balanced Power Technologies Ultra-3.5 unit; mine is the first BPT-3.5 built using his then-new six-duplex-outlets chassis. (I had sent him six Furutech duplex outlets and a Furutech 20-amp IEC inlet.) Powercables are mostly Furutech UP-OCC-copper, 13g. to the DP and preamp and 11g. to the main poweramps, with DH Labs Power-Plus 12g. cable to the M700. ALL components are driven by the conditioner with long cables running from the conditioner at left, around the left-front corner, against the front wall, and then to the amps; some is visible in the pic. I have three dedicated 20-amp branch circuits running into the musicroom; only one is used now, to drive the conditioner.
ALL cables for the three front channels are lifted off the carpet with DIY, plastic-tube-based elevators, and different kinds of cable are dressed carefully to cross only at 90 degrees and at least a couple inches apart.
The SWs are equalized with a pair of small, commercial, single-channel RANE parametric eqs. Each eq has three sections, each adjustable in (1) center frequency continuously from something like 10Hz to 2kHz, (2) the width of the notch/peak (‘Q’), and (3) gain. These help greatly in taming the main 28-30Hz room node and two other notches or peaks.
I’m VERY happy with the sounds of my system, and I expect it to sound even better with the BHK '300s replacing the surprisingly good-sounding Butlers.
I listen to, mostly, large-scale Classical and film music, and mutichannel SACDs sound simply dazzling. Another upgrade soon will be a Marantz AV8805 pre/pro.
