I have just bought Polk AMR130 powered 5.1 speaker system. All's great.
Problem: Transformer makes a hum sound, that is audible at night. It's not too bad, but with my ears (which God shaped to detect noise) ... I cannot hear the hum when music is playing. Before going to sleep, I pulled the power plug out to get rid of it.
The system is under 30 day satisfaction guarantee, so I can get it replaced from the reseller, but I am not interested in that. Other option is to have transformer sent to Polk and have it repaired or replaced. (Third option is to live with it.)
Hum sound is not too bad, but I know that transformers which are OK do not make it. This transformer is certainly abormal. Question is should I get it replaced, or whole system replaced (not preferable), or live with it. Looking for advice at first.
