Current key kit (digital stereo signal path): Anthony Gallo Acoustics Reference 3.1 speakers; REL T/5x subwoofer; Emotiva XPA-1 (MK I) mono-block amplifiers; Anthony Gallo Acoustics Reference SA amplifier (to drive the second set of voice coils in the Ref. 3.1 woofers); Anthem AVM 50v 2 preamplifier/processor (with Anthem Room Correction software); Modified PS Audio PerfectWave DirectStream DAC (MK I) plugged into a MSB Technology Isolation Base/Grounding Device; PS Audio AirLens Network Bridge/“Streamer” (feeds the DS DAC with a Revelation Audio Lab I2S cable).

Pink Faun LAN Isolator; Giga-Foil LAN Isolator; EtherRegen Ethernet Switch; TP Link gigabit Ethernet Switch; TP Link Media Converters; AT&T modem/router; iMac desktop computer. The iMac (along with compatible portable devices) allows me to stream ripped and downloaded files stored on it (and a Synology NAS) via JRiver Media Center; and my Roon Core subscription, with Qobuz subscription integration allows me to stream music from the Qobuz database (as well as my iMac and NAS files).

Power “conditioning” is via PSA P10 Regenerator (served by a Swiss Digital Fuse box in lieu of the internal fuse which has been replaced with a copper “Sluggo”); Shunyata Research Venom Amp-1 conditioners (2x for the mono amps, plugged directly into the wall with the Pangea 20 amp PCs; PSA AC-12s run from the Amp-1s to the Emotivas); Monster Power Signature Series AVS 2000 voltage stabilizer and HTPS 7000 conditioner, an ADCOM ACE-515 power conditioner, as well as a scattering of PS Audio Noise Harvesters and AudioPrism “quiet line” power filters (MK III).

Miscellaneous power cables, including PSA AC-12s and AC-10s, the Pangea 20 amp cables, Shunyata Taipans for sources and one, older Synergistic Research PC whose model number escapes me (connects the DS DAC to MSB Isolation Base). Other interconnects include WireWorld ethernet cables, Nordost Red Dawn speaker wires, Better Cables and Iconoclast XLR cables.

I also spin some discs to feed the DS DAC from time to time with a PS Audio DirectStream Memory Player feeding the DAC with a Revelation Audio I2S cable. The DS DAC and DMP both rest on PS Audio PowerBase isolation bases.
