I own a XR55 and a SB3. I recently purchased an external DAC(mhdt lab- Constantine) which will arrive in a few days. I thought that I could upgrade the output of the SB3 without going the mod route by bypassing the SB3 DAC with the digital out> DAC> audio out> XR55. So are you saying that this is a waste of time and money? I thought that if you input a digital signal via SB3 optical/coaxial to the XR55, it would make use of the receivers internal DAC. On the other hand, if you input an analogue signal via external DAC, the RCA audio inputs, the XR55's DAC would be bypassed. I guess that I'm a bit confused but is there another DAC right at the amplifier stage that causes another digital/analogue conversion therefore more complexity and less SQ? -- rajacat ------------------------------------------------------------------------ rajacat's Profile: http://forums.slimdevices.com/member.php?userid=4156 View this thread: http://forums.slimdevices.com/showthread.php?t=22502 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
