Tiffany...I have read according to ps audio's website that the unit will indeed eliminate all if not most of internal transformer hum. In fact, I visited the site to do some research and according to them, if I remember correctly, an amp that hums w/o any thing connected is perhaps in need of repair. But owners here say it's the nature of the beast!!!!???? I should be grateful it powers up and works. But that hiss, buzz, slight hum is still bugging me. I don't see how an electronic device that received superb reviews and price lists in the thousands can be broke if it makes a little bit of noise. But then again...?
added amp...now hiss from spkr's
Addd an amp to the mix. SS multi-ch. Had no problems prior in relatively simple rig or atleast I did not notice. After making connections to recv'r(now used as pre/pro) I noticed a slight hiss/static like sound comimg from mids on my spkr's. So the process of elimination/isolation began. Long story short, I narrowed it down to the hiss/buzz coming from spkr's with only the amp connected. Nothing else...no interconnects no nothing. That cancels out cable problems, bad dvd player, etc, etc. Just power cable plugged in and wires going from amp to spkrs. When powered on it makes the noise. Amp runs quiet as far as I can tell when putting ear next to it. What's the deal? Tried diff outlets, diff spkr...makes no difference. When taking amp out of the mix and connecting spkr's to recvr, there is no noise at idle. Amp plays fine/sounds fine but the noise, although slight, is bugging me to pieces. Amp was shipped to me and had shifted cady/catty corner while in it's factory packaging which is pretty substantial. Perhaps it took a hit/drop...weighs about 80 lbs! Could something have gotten jared loose...a transformer which it has two of and quite large. Or is it the nature of the beast to output some noise when at idle? Thank you.
