I have just switched to the latest version of SL and bought new version 2 vinyls. I still have a high pitch noise that emits from the turntable's interior speaker. Very annoying. I have always had it. I am running two tech 1200's, a pioneer djm600, a dell 5150 p4 3.2 w/ ht and 1gb ram. I power the sl unit via the usb on my laptop. Anyone else get this annoying hihg pitch sound? I tried to make a mix tape last night and I could hear this sound in the background of a few songs. The plaayback quality of my songs doesn't sound as good either. And yes, I have checked all of my mp3's and my setup green circles are very round. Not perfectly round, but as round as I could get them.
