Years ago while in Germany I listened to one of these preamps set up and was very impressed. Never did buy one in Germany. But a few years back snagged one off ebay for $40.00 . Well it looked nice but the sound was terrible phono preamp dull lifeless and tone controls added very little if anything to the audio. So i opened it up and to my disgust found that whoever soldered the boards had to have been trippin. Solder specks all over the boards and solder points actually touching other solder points that weren`t supposed to be joined. I cleaned the boards redid all the solder connections in the whole unit and turned it on. Yea that was the cause of the overall bad sounding preamp. To this day it is a very fine preamp. It was designed by a man who left McIntosh to join Phase Linear. So if anyone has one that there not using because of poor sound quality I highly advise them to open it and see if the soldering is crappy!
