my set up features mirage omni speakers and a HK avr 225 50w x 5

this last week ive been using some large gauge ebay cables, they are about 10-11 gauge terminated with gold bananas, prior to that i had acoustic research 16 awg bare wire. but i now have a strange occurance. when i shut off the system i hear a "Poof" sound, as if tightly enclosed air was pushed out very quickly, kinda like a low frequency pop.

i never had this sound when i used the 16 awg cables, is this from bad cable design? or could these cables be too large for my HK? i noticed a volume increase, with these cables too. what is that sound? should i be concered? maybe its my surge protector? im using a crappy old belking one right now.

I would look for something besides the speaker wires. If you wanted to, you could hook your old ones up just to be sure.

Just to clarify, is it like the sound you get when you plug in a y-adapter to a portable CD player while the reciever is on?
