If your preamp is SE, you need to have the pins in the balanced input on the amp for SE to work.
Cary SLP98P not working with Audio Research VT100
HELP!
OK, a few months ago after doing a bunch of research to build a new system in a smaller room, I bought some Harbeth SHL-5's and an Audio Research VT100 MKIII amp to match with my existing Cary SLP98P F1 preamp.
When I first got the combo together they sounded amazing, but after a few hours of playing the sound started to degrade then it got really wierd:
The Audio Resarch amp started to pulse. The tubes would two at a time sequentially pulse lighter (losing thier blue hue) and the sound was terrible pulsing on and off as well. If I leave the system off for a long time then start again, the process starts again.
If the amp is attached only to the Oppo 105 I have on the rack, it has no issues. If the Cary is connected to the old Parasound amp I have on the rack, it works fine.
The Cary just came back from an update at Cary, it was doing this before the update, and this seems to have had no effect.
What could this be?
Some suggested DC from the preamp, but I just got it back, and would that build up?
HELP!!
