* Acoustic Revive DSIX-1.0PA AES/EBU from Alpha USB to Alpha DAC.

Analog ICs:

* T.G. Audio High Purity HSR (with Xhadow RCA connectors): Alpha DAC -> JC-2 -> Merlin BAM -> BBQ

* VH Audio Pulsar w/ Eichman RCAs: JC-2 -> subwoofers.

Speaker (spades all around):

* T.G. Audio HSR & TG HSR jumpers


* Dream State Dreamcatcher from wall feeding Sound Application RLS-1.

* Elrod Statement from wall feeding BPT balanced conditioner.

* Tel Wire PCs (original low-current) from the BybeeSucker feeding USB converter, DAC and linestage.

* Tel Wire HCs from the RLS for BBQ amp.

Other (Power Conditioner, Racks etc.): * Cryoed Oyaide R1 receptacle at the wall with WPC-Z cover system.

Power Conditioning:

Front End: BPT 2.5 signature balanced power conditioner feeding a T.G. Audio BybeeSucker (Oyaide R1 outlets in both). Alpha USB, Alpha DAC and JC-2 linestage each run from separate circuits on the BybeeSucker.

Amplifier and Subwoofer: Sound Application RLS-1 feeding the BBQ amp and Force subs.

Two Hammond 193M chokes employed - one at the wall, the other into the BPT.


* Hardwood (teak?) cabinet that's not intended for this purpose, but it holds the gear up and looks nice.
Tweaks: Isolation:

* BDR shelves and myrtlewood blocks under digital server and linestage.

* BDR cones (MKIII)) under the Alpha USB and Alpha DAC. VPI Brick on top of Alpha USB for stabilization weight.

* Polycrystal amp stand on floor with TG Audio Pointy Thangs between stand and amp chassis.

* Herbie's IsoCups with Gabon ebony balls under the Sound Application conditioner.

* BDR MKIII cones under BPT conditioner.

* 3" thick maple blocks (Timbernation) under the Merlins, with Z-feet spikes directly into the maple. Herbie's Big Fat Dots between the maple blocks and the hardwood floor. This really helps with the suspended wood floors.


* EVS Ground enhancers on Merlin (-) terminals.

* BudP-style ground loops on (-) speaker terminals of the BBQ.

* DIY RC networks following Al Sekela's multi-tier recipe (I use these in place of the ones provided by Merlin).

* Various types of crystals from Alan Maher near power supplies.

* Synergistic "quantum" fuses (Berkeley gear) and HiFi Tuning "supreme" fuses (preamp & amp)
