Bought two units of older model few years back (PSW110) and it broke by just sitting there, in standby mode (got VERY little use and started buzzing while in standy mode). Now it just buzzes and crackles instead of making sound.
I’d stay away from PSW series.
By the way, Polk lists this at $399 on their own website, not Woot’s highly inflated (as usual) list price.
