static charge

I had a similar issue with a new Acurus A250 some time ago...little static-ish sound from one side...sent it back twice for free warranty repair and then sold it.

quick check. swap speaker cables and see if issue follows. sounds like it should but.....

they switch outlets if possible. see if you can confine to your amp by component swaps.

if amp........? repair I guess.

Sounds as a problem i also experienced.
Static noise, which came and went (left channel).
Not bound by choice of level (amp) or in any case provoked by choice of discs (cds).
My amp was changed for another unit as i heard this even when source was out of system.
That is, only amp connected and speakers cables.
When amp came back - same problem, but only with cdp connected.
So, all cables were sent back for check up.
No problem, nothing faulty.
What was told was, the first amp had leaked DC and damaged analog output of cdp. This seems weird!
So, i bought new analog parts for cdp (both channels).
I'll have to wait and see when cdp returns how this is solved.
Time-consuming and expensive!

Sounds like a Turkey to me.

Turkey or not, all issues resolved.
