hmmm, not sure about introducing jitter (jitter is about the timing of the packets as far as I understand). This might be interesting reading (I realize that this is the company's info, but the benchmark DAC I-USB gets good reviews; mostly just a starting place for a little bit more on USB DACS): http://www.benchmarkmedia.com/dac/dac1-usb Also from their website (again, I'm not suggesting this is gospel, just interesting -- and I do own a Benchmark DAC I, but an older model where I'm using S/PDIF for connecting). And note the last sentence below. ============================== Several tests have been performed on third-party, USB-to-PCM converters to determine which technologies are bit-transparent, as an ideal USB-to-PCM converter should be. Native USB audio devices, like the DAC1 USB, have been found to be bit-transparent. Native devices are defined as those devices which use the native USB audio drivers, versus special, custom drivers. All non-native devices tested were found to NOT be bit-transparent. The Benchmark DAC1 USB is unique in that its native USB audio support extends to 24-bit operation at sample rates up to 96 kHz (with fully automatic sample rate transitions). All other native USB devices tested, including 'high-end' digital-to-analog converters, are limited to 48 kHz, 16 bit. We have not been able to find external USB interface that delivers the same level of performance as the interface that is built into the DAC1 USB. 24-bit capability is essential even when playing 16-bit material. The 24-bit capability prevents truncation in the computer caused by computer-based volume controls. A common problem with USB audio is the presence of pops and clicks. The DAC1 USB is also unique in that it is immune to these pops and clicks. -- garym ------------------------------------------------------------------------ garym's Profile: http://forums.slimdevices.com/member.php?userid=17325 View this thread: http://forums.slimdevices.com/showthread.php?t=84903 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
