My Ayre AX-7e amp does not do that either. The above post is the best suggestion. Please call Ayre and describe the problem to them. I also suggest you not use the amp until this problem is fixed.
Ayre AX-7e Static Discharge
I just got myself a used AX-7e and everything is working perfect. My only question now is everytime i turn off the main power (even after putting the amp on standby), i could hear a whirling sound coming from the amp and there will be a slight static discharge (or a slight thump) coming from the speakers. My guess is its due to the caps discharging but shouln't an amp costing this much have some kind of circuit to eliminate this noise? Or is there something wrong with my amp? Hope someone can help me clarify this issue. I am worried that it may damage my speakers in the long run.
Thanks
