The clocks in my DAC are STUNSU STGJ3s which are spec'd to that figure for frequency stability. My TacT 2150 doesn't have a clock output. I never claimed to have special hearing ability. I don't know what's causing the SQ differences I'm hearing. Ask www.empiricalaudio.com about I2S. You obviously aren't amiliar with the TacT 2150. It's a power DAC. It takes a digital signal on SPDIF or AES/EBU. You can install an ADC card, but why would I want to feed the TacT an analog output from the TP's DAC and run it through an ADC? -- jhm731 ------------------------------------------------------------------------ jhm731's Profile: http://forums.slimdevices.com/member.php?userid=7685 View this thread: http://forums.slimdevices.com/showthread.php?t=32993 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
