Hello.
I have the high-pitched noise on my recordings via my new NAD PP3 pre-amp. I don't think I will be able to return the unit as I bought it on eBay and stupidly discarded the packaging, thinking it was working fine (which it is as an amp) before trying the USB recording.
I have a fully licensed copy of VinylStudio and would have thought I could take the noise out but don't seem to be able to. Do you have any advice?
Yours out of pocket,
