I picked up a used Acurus Act-3 as an interim solution for my lack of a pre/pro.
It has been nothing short of an excellent little performer for the first week. I had no complaints considering the rock bottom price I paid.
Then I throw in a CD yesteday and listen for about an hour. Everything is fine until I move on to the second CD. I noticed a subtle hum in the center channel even though I was in stereo mode.
It wasn't too noticable from my listening position and I remembered how much I paid for the Act-3 so I let it go. 15 minutes later the hum had spread to the L & R channels and grew MUCH louder. I had to turn it off.
I let it sit overnight and tried it again today. Same thing. Annoying as hell.
Ground loop? I don't think so, it just suddenly appeared. I guess it could be my amp but it's NEVER been pushed hard so I seriously doubt it. I thought I'd seek advice from you guys.
