I agree with Mofi, it sounds like the Shrimp is leaking so DC which is tripping the Ayre's protection circuits. Maybe some caps need to be replaced in the Shrimp.
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??
