By the way, could you post your thoughts here in this thread as well as CA? That would be great.

Thanks for those kind words, John - I hope I can continue to live up to them.
Went to your CA part, liking forward to getting my unit. Have to say, didn't know what most of the stuff you have in the set up IS...just recently learned about LPS from feeling with the Geek Out 1k (have the Special Edition). I think the voltage is the correct one for the GO...is there a benefit to using this along with our instead of a Vaunix Lab Brick powered hub, which I use now? Thanks.
Hi doctorjazz,
The USB Regen will only pull
data from your Mac or PC's USB port - or from an Apple device that has a CCK (camera connection kit).
The USB Regen will
ignore any power that arrives at its input via the USB cable from your source.
It gets its power not from its USB input, but rather from a separate, 2.5mm coaxial barrel connector, requiring a
minimum supply voltage of 6V, up to a maximum of 9V (if your DAC pulls 5VDC power from your laptop or PC), or a maximum of 12V (if your DAC is internally powered and thus pulls no power from your laptop or PC.)
But again, the minimum is 6VDC (with a continuous current rating of at least 1 Amp) and your Vaunix hub, though wonderfully regulated, only supplies 5VDC.
So, where do you get 6V to 9V power (for a USB-powered DAC/amp like your GO 1000?
The USB Regen comes with a 7.5V SMPS (switch-mode power supply) that you can use to power the USB Regen (and your GO 1000 that's plugged into the USB Regen).
Early adopters have found, however, that the better your downstream gear, the more attention you'll want to pay to providing the USB Regen with really noise-free power.
Many people will no doubt be completely happy with the included 7.5V SMPS, but others have found that, for their ears and gear, the benefits of the USB Regen can be taken further still by improving the power supply to the Regen.
There are people out there using the $925 UpTone Audio JS-2 power supply and testifying that their $175 USB Regens can appreciate the difference.
I'm currently experimenting with much less expensive power options for the USB Regen - the $45
TeraDak U9VA 9V (adjustable) linear power supply and an Anker Astro 3 LiPo battery pack operated in 9V mode
(now rebranded, as seen here).
Alex Crespi (Superdad) has already announced a new UpTone Audio product that's still in the design phase, which can optionally be inserted between their standard 7.5V SMPS and the USB Regen, to vastly improve the power quality coming into the USB Regen - so stay tuned for more information about that critter. Pricing and a release date are not yet available. It doesn't even have a name yet, but lots of people already want it - such is their confidence in UpTone's John Swenson - to hit another one out of the park.
Meanwhile, there's plenty of audible improvements to be enjoyed just using the USB Regen with the included SMPS. They spent a lot of time testing off-the-shelf SMPS units before selecting the one they are shipping with the USB Regen.
Everything that can be tweaked will be tweaked, so it's no surprise some people are spending a lot of money to improve the power supplies used to drive the USB Regen, but you really don't need anything other than what comes with the USB Regen to enjoy what a lot of people are calling perhaps the best bang-for-the-buck they've ever had with an audio purchase.
