Excuse my ignorance for I have not had the time to read this entire thread, but does anyone know if this noise problem also shows up in the Pinnacle Soundbridge M1001?
And what about the Pinnacle Soundbridge Home Music?
That would be a "yes" on both counts, with the provisos that:
1.) Not everyone can hear it.
2.) I believe (please someone correct me if I am wrong) that those who can hear it only hear it with certain 44.1 kHz tracks, not all
44.1 kHz tracks.
3.) You can avoid the problem if you re-sample to 48 kHz on your computer. To do this without sacrificing quality, you will need to re-rip your CDs with the appropriate settings, unless your library was ripped to a lossless format. (In which case you can perform the upsample process on your computer without loss of quality, it'll just take a while.)
