When you are running analog signals, analog RF can bleed into nearly everything. I live about 400 meters from a 50,000 watt FM station, and its RF bleeds into nearly everything. Its one of the reasons all the cabling in my studio is balanced. And if I turn up my tube guitar amp to 11, I can hear the radio station unless I'm very careful. Back when I had a separate FM tuner and amp setup, I could tune in the station, and unplug the tuner, and still get lots of signal out the speakers. Analog amps tend to amplify everything. But if the DAC is properly isolating the Digital from the Analog side, you should have a problem. The 172Kb/s on off stream doesn't modulate into anything audible by humans. It seems to me that if you are feeding the output of a SqueezeBox to an external DAC using SPDIF, you should expect not to have a problem. There is no sense replacing the SqueezeBox DAC with one retailing for under a couple hundred bucks. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
