My system resides in a 24x20 room with a 18ft cathedral ceilings. Always striving for maximum bang for the buck, I have eschewed snake oil for substance, bought most gear second hand, and make certain cables and minor mods myself.
In the 2-1/2 years since I entered this hobby this system has evolved as follows:
Speakers: AR90, Polk SDA-2, ADS L1530, ADS M20, Acoustat Model 2, Acoustat 2+2.
Analog High Current Power Supply for the PCA-2 preamplifier.
PS Audio NuWave DAC
Three digital inputs 192kHz asynchronous USB RCA and XLR balanced outputs High current class A output stage Native mode 192kHz selectable upsample Low jitter PerfectWave clocks Class A fully balanced discrete analog electronics Burr Brown 24 bit DAC chip
