Have you tried new tubes in the pre? I had a bad tube in my Audio Research pre cause an amp to shut down.
Ayre V-5xe pops off/Manley Shrimp
Just purchased this amp and when I power up the Shrimp pre the Ayre pops off. I have changed interconnects and power cords with no change at all. If I run the Ayre directly into my Audio Aero Capitole it's fine, so I am guessing there is some type of an issue between the Ayre and the Shrimp. Thoughts??
