Selling my Uptone Audio USB regen as no longer required. Purchased it direct from Uptone October 2015, now selling for $175. Shipping to the UK added around 20% so ended up paying over $200. This is complete with a US lead (new owner will need to supply UK/EU kettle lead) as per the Kit contents below. £95 to a new home including next day delivery.
If you don't know:
The USB REGEN takes the digital audio stream from your computer or other music streaming device, and generates a completely new USB data signal to feed to your DAC. It accomplishes this by combining a carefully chosen USB hub chip with an ultra low-noise regulator and low-jitter clock. Importantly, it does so with ideal impedance matching—right at the input of your DAC.
The USB REGEN kit includes:
a) the REGEN itself in an all black with silver-printed aluminum case (57 x 46 x 18mm); Input is USB 'B' jack, Output is USB 'A' jack, DC jack is 5.5mm x 2.1mm.
b) the best spec'ed and sounding 22 watt/7.5V/2.93A (overkill) tabletop (93 x 54 x 36mm) world-voltage-compatible SMPS we could find (use a nice linear if you want—in the range of 6-9V/1.5A is fine; or even 12V if you are certain that your DAC is not deriving much power from USB bus); If you own an UpTone JS-2 LPS, then you can consider using one of its outputs—set to 7V—to power the REGEN very nicely!
c) an 18-inch long Volex 18awg power cord to go from the SMPS to the wall (get fancy if you like, or if you are overseas use a power cord with locally appropriate plug);
d) a male/male USB A/B solid adapter plug (for hanging the REGEN right from the back of your DAC; maybe stick a block of something under it if you feel it needs support);
e) a 6-inch male/male USB A>B cable if things are too tight around your DAC's USB input or you just don't want to use the solid adapter.
