|Preamplifier (or None if Integrated):||Rotel RC-970BX|
homemade passive pre for sub volume control
Behringer DSP 1124P

then equalized by Behringer DSP 1124P
Mains running full-range with no EQ,
but protected by 30Hz hi-pass filters
(-3dB at 29Hz, 12dB/octave slope)
Approximate measured in-room freq response:
27-20 +- 10dB, w/totally flat bass down to 28Hz
but sharp drop to 0dB below 27Hz
(literally, it's like a cliff to nothing)
|CD Player/DAC:||NAD C542 CD player|
|Turntable/Phono Stage:||Pro-ject Debut Carbon DC|
Ortofon 2M Red cartridge
TC-750 phono stage
w/upgraded power supply
|Other Source(s):||Harmon Kardon TD302 cassette deck|
Yamaha TX-492 tuner
w/ Radio Shack tri-drive yagi antenna
w/ RCA signal booster
Gateway laptop for digital and streaming
w/ Fiio E10K Olympus 2 USB DAC
bit-exact streaming using Foobar2000
|Speaker Cables/Interconnects:||Speaker Cable =|
bi-wiring mains with unterminated
Monster Standard S16-4R 16ga bi-wire
preamp to main pwr = XLO/VDO ER-5 (.5m)
preamp headphone out to sub xovers =
Monoprice premium coax 3.5mm (6')
w/ Radio Shack 90 degree 1/4" to 1/8" adapter
bass xovers to EQ = Stinger 1000 (.5m)
EQ to sub volume control = Mogami 2534
sub volume control to sub amp =
WireWorld Solstice II (.5m)
CD to preamp = WireWorld Orbit III+ (.5m)
USB DAC to preamp = SKW
tuner to preamp = generic (NAD OEM)
turntable to phono amp = Pro-ject OEM
phono amp to preamp = WireWorld Solstice 7
tapedeck = Radio Shack Gold Series
|Other (Power Conditioner, Racks etc.):||Tripp Lite Isobar 12|
StudioTech HF Series 5 shelf rack
|Tweaks:||1. Dedicated 20A circuit with 10ga wiring and hospital grade outlet.|
2. Damping Tac all over phono preamp.
3. Damping Tac on amplifier fins.
4. Flagstone isolation platform for turntable.
5. Speakers bungie-corded to stands.
6. Subwoofer amp being driven by headphone output of preamp (2nd pre-out is driving zone amp in kitchen). Sub seems to have more punch this way.
|Room Size (LxWxH):||16 x 15 x 10|
|Room Comments/Treatments:||Old house with wood floors and high ceilings.|
Entire end wall where speakers are is a bay window.
Two walls have large thruways, so room is actually fairly open.
12' from speakers to main listening position.
|Music Preferences and Comments:|
|Music Used (Genre/Selections):||'80's rock (INXS, U2, Cure, etc.)|
techno (Chemical Brothers, Infected Mushroom)
jazz (Bluesiana, kd lang)
|System Goals/Comments:||This system sounds quite good and is just about perfect for the size room it is in.|
|System Strengths:||1) sounds very good, especially realistic on vocal, folk, and jazz music|
2) Value. The complete system was around $3600.
|System Weaknesses:||1) could be more convincing on full scale classical music|
2) limited absolute maximum volume and impact.
3) imaging isn't the best--mostly due to speaker placement and seating position, I think.
|Video/HT System: None|
