I purchased this V-DAC approx. one year ago. It was new and I am the original owner. This unit has worked flawlessly at all times. Approx. 600 hours use. I once used a regulated 12 volt power supply and cut the stock power cable a couple feet from the plug. This cut has been spliced back together and has been in use this way for 3 months using the stock transformer. I needed the regulated power supply elsewhere and honestly, I can't hear any difference anyway.
I knock points off for the cable splice. If you want to buy your own power supply upgrade ( $40+/-), you could make a cut at my splice or build your own heavier guage cable.
Price including Priority USPS shipping to CONUS : $235 (PayPal)
