For computer-clueless can make the transition in Dynavox USB phono preamp UPR 2.0 for digitizing drives some to pose riddles. I do not count myself to the inexperienced, but still had two hours "fun" until I brought everything up and running, so I was satisfied. The reason were dropouts when digitizing, so two- three per single plate, so to about 2 minutes, and that was absolutely unacceptable at a time of dropouts by about half a second. Changes to the volume control brought no other results. I came across the Dynavox website and found this device to download a file that I downloaded, I unpacked and installed. After that dropouts were gone! So when someone makes the same experience - do not despair, and down load the file and install. From the sound of her I am quite satisfied. Of course, it might be better equipment, but then already for three to four times the price. Everyone needs to know himself whether the pleasure it is worth so much. My turntable is an old original Dual 510 with Shure M95, the well to fit signally. I see it as an advantage that you can control the gain. That the power supply of this is did not bother me, I had something suitable in the drawer. And if not - as some costs not Hauseck.
