Suburb or Town: Clifton Hill State: VIC Payment Method: Paypal, EFT, Cash on Pickup etc Reason for selling: Further Information: I picked up this unit a few years ago, and it made a big difference to the sound of my system. Details from the Uptone site: https://uptoneaudio.com/products/usb-regen 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. Although the REGEN does not eliminate all sound quality differences between USB cables in a high-end system, it significantly reduces those differences. John Swenson has written about how the PHY chips and processors at the input of every USB DAC (even those with galvanic isolation) are sensitive to "packet noise modulation" and ground-plane noise—caused by poor signal integrity and impedance mis-matching. Every USB audio source (computer or streamer) and cable causes this, every DAC is affected by this—and the REGEN is the cure. The USB REGEN's secondary function is that it disconnects the computer's noisy 5 volt bus power coming down the USB cable, and provides clean 5VBUS on its output--for DACs that need it—via a second ultra low-noise regulator.
