There's something digital going on (duh...). I mean, I have the Geek Out Special Edition, no popping problem. I also have the CEntrance M8, and it does exactly what you describe. If you've ever played old, scratchy vinyl records, you'll know the sound. Sent it back to CEntrance twice, nothing wrong. I'm guessing (in my total ignorance) it has to do with some setting, maybe some sampling rate discrepancy or something (the CEntrance is unusable from my PC, works fine from an iPad). Never figured out exactly how to fix it (or how to get sound it off my PC through anything other than JRIVER, for that matter). Boy, and people think vinyl is a pain! Any other ideas out there?
