First things first: Merry Christmas and/or Happy Holidays everyone! We are in Portland OR with our daughters and families, presents are opened, pumpkin bread is eaten and oldest daughter Heather has the prime rib in the oven. Life is good!
On to the DigiBUSS.
The Digi was designed as a bi-directional digital noise filter to KILL the digital nasties that are the rule not the exception these days. iPhones, computers, power meter telemetry, kitchen appliances... everything has a chip or 9 insides anymore. That is a bummer for most people. It is also designed to be a better impedance match with SMPS than either wall supply or any of my BUSSes. This is extremely important in the context of SQ. This is particularly noticeable in soundstage dimensionality and timbre of acoustic instruments and the human voice (sibilance).
There are a couple of recommended ways to use a Digi.
I originally designed it to power all of the SMPS in my office/lab. Even located at the opposite end of the house on the opposite branch circuit, I could hear the difference in SQ when all of the SMPS were on or off. Sucked. The second prototype solved the problem.
Secondarily, it can be used as a standalone filter for a small system. There is no PFC and it does contain an inductor, but the indicator is rated at 25A and the series resistance is < .001 ohm.
The primary audio function is to prevent digital hash from screwing with power supplies in a local system. It will prevent RFI from polluting the PS of a digital source and/or DAC. It will prevent the source and DAC from contaminating preamps, amps, crossovers... whatever.
Noise reduction begins at 120Hz. 100kHz is ~ -100dB down. This frequency is where a majority of "digital filters" are at -3dB. You can see why it is sooooooo quiet. The 3 P&S 5362A Extra Hard Use Spec Grade are split into 2 outlets, each with its own filter for maximum noise reduction. Choice of Furutech gold or rhodium plate inlets or a Neutrik powerCon input connector. Standard finish is that adorable black textured finish that saves hundreds of $$$ in selling price. Custom colors and enclosure materials are available. Anything you can dream up I can do... you just need to be able to afford your dreams. :)
Additional and different receptacles are available, just inquire.
Mike C., for your system, plugging it into the Uber is definitely recommended. Mike R. No doubt that you are hearing the goodness of no hash. What did you find out after you sobered up? :rofl: Then again, the best application is the one that sounds the best in YOUR system. Please share your findings. Inquiring minds want to know.
Let me know if ya'll have other questions.
Ho, ho, ho.............

Well after one week of burn-in it is still changing. However the bass, and dynamics are so much better. The top end needs more time like the Uberbuss.
The Furutech rhodium duplex has a more natural presentation out of the box compared to the P&S. However not enough time on hand to tell.
So far a quieter background with explosive dynamics. No Hi Fi sound from digital anymore. It is gone, gone and gone.
Kudos Dave it is a winner.

Thanks, Charles for the nice review. Breaking does take time. The GTXD-R is a study in bipolar, paranoid schizophrenic audio gear. Way weird to a a few weeks and then AWESOME.
Who knew?!?
Enjoy,
<><

Found another use for this baby. You have wall warts ? If ya do then take a power strip plug them all in and plug into Digibuss and be very happy.
Next up is trying with Arion class "D" amps.
