Ok, I understand now.... What they're doing is building a 4x oversampling unit, with a linear transfer function, in hardware, rather than in software. Seems like a slightly expensive way to implement it, although it would allow you to use slower DAC chips than doing the oversampling in the digital domain. You also get an improvement in the SNR, due to the DAC parallelization. -- DCtoDaylight Audiophile wish list: Zero Distortion, Infinite Signal to Noise Ratio, and a Bandwidth from DC to Daylight ------------------------------------------------------------------------ DCtoDaylight's Profile: http://forums.slimdevices.com/member.php?userid=7284 View this thread: http://forums.slimdevices.com/showthread.php?t=62747 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
