Basic Information

Audio System
Music Server(s):
Buffalo Linkstation
Music Server Operating System:
Linux
Preferred Digital Interface(s):
USB, FireWire, Ethernet (UPnP/DLNA)
Digital to Analog Converter(s):
Ross Martin Audio Dual PCM1794 Router, Korg MR-1000
Digital to Digital Converter:
ADC: Korg MR-1000, Aqvox Mic 2 A/D, Mackie Onyx 1200F
Preamplifier:
Bryston 11B, B&K Reference 30, Aqvox Mic 2 A/D, Grace M101
Amplifier(s):
Ayre AX-7, Elan Z661, Acuvox
Loudspeakers:
Earthworks Sigma 6.2, Dunlavy SC-1, Acuvox
Interconnects:
Least of my worries. I measure analog interconnects for low capacitance and near zero dissipation factor with my GenRad impedance bridge. I have found ones that meet these criteria at Radio Shack among other sources. I can hear a difference between these and some expensive cables, but there are no recordings or speakers that make them the limiting factor. Since I listen to acoustic music MORE than I listen to speakers, my observation is authoritative. I have a piano and three harpsichords in my living room played daily and attend over 100 acoustic concerts a year in the best halls in Manhattan.
Loudspeaker Cables:
Room design, setup and treatment is about 1000 times more important than loudspeaker cables. My reference two channel system is in a 28' x 35' room 50% of the volume filled with large scale fractal diffusion and the subwoofer is located at the Golden Mean division of both plan dimensions. I use 12AWG fine stranded, high purity, low DF contractor wire from Liberty Cable.
Power Cables:
Stock from my bin of IEC cables. I have dedicated 20 Amp branch circuits on Medical Grade toroidal high-isolation transformers for every AV system; and custom surge arrestors I designed that were tested with actual lightning hit on the pole transformer resulting in zero damage, while all other electronics in the building were destroyed.
Remote Control(s):
Bad for your health - get out of your chair or stop fiddling and listen.
Miscellaneous:
I design and build amplification systems that mimic the acoustics of sound boards and wind columns so they match the polar radiation pattern, timbre and transient responses of traditional acoustic instruments. I deploy them in strict one mic-one speaker configurations because conventional audio engineering is temporal, spatial and dynamic distortion: mixing, panning, EQ, reverb, compression, dubbing, splicing, etc. My systems are used for live performance and recording acoustically with proprietary near coincident arrays, two mics for stereo and six for 5.1 surround.
Dream System:
Acuvox OVOMOS (one voice, one mic, one speaker). Many people have theorized about reproducing a string quartet with a cello speaker, a viola speaker and two violin speakers. I built it, and it is the first audio system transparent to the ears of conservatory trained string players. It is the dream system of people who hate all speakers and audio systems.
Headphones:
Sennheiser HD590 (flattest bass), Beyerdynamic DT770M (best isolation), Shure E2C (very flat in-ear), Ultrasone HFI-650 (best imaging). I hate headphones but keep buying them, nobody gets enough right.
Headphone Amplifier(s):
Acuvox, Total Bithead, Creek OBH-11
Portable Player(s):
Laptop with Total Bithead, iPod Touch (ALC) with Total Bithead or Wadia 170i
