I've had my VPI Scout w/ JMW-9 Tonearm for 2 years. Prior to 2 weeks ago I ran the Scout to a Pioneer Receiver through a Clearaudio Nano phono preamp w/ no noticeable 'hum' or 'buzz'. Within the last 2 weeks I've purchased a Rotel RB-1552 Amplifier and the RC-1580 Pre Amp to set up a 2 channel system w/ the Scout as my main source. Both Rotel products and the Scout were purchased brand new. My power source is a Monster Reference Power Station, my cartridge is a Soundsmith SMMC2, and my interconnects are MIT Terminator 6. I am running the Scout directly to the RC-1580 phono stage (the Clearaudio Nano is not present in this set up). When I turn on the system and activate the phono stage I get a loud 'buzz' at low to moderate volume. It seemed like a grounding issue so in addition to running a ground from the Scout RCA box to the pre amp I have run a ground from the plinth to the RCA box as well. I have also tried running soft bare copper wires around the unshielded wire leading to the Lemo connector and grounding it to the Scout RCA box (Soundsmith reccomendation). Other symptoms include a 'pop' when I touch the back of the tonearm, static shock when I touch the other components in the system, and an increase in 'hum' and 'buzz' when I touch anywhere on the tonearm. Any thoughts?
