Yes Raja, I think the Constantine is unneeded with the XR55. The signal has to get re-converted back to digital again to go into the amplification stage, so the high-quality analog output of the Constantine is in a sense going to waste. Going straight from the SB's digital ouput into the XR55 should sound excellent. I wouldn't regret buying the Constantine though, maybe it's time to start a great headphone rig? (I have the Renaissance and the Dialogue II and I really like both DAC's.) You'll want the Constantine for pretty much any non-equibit amp. -Dan -- dwc ------------------------------------------------------------------------ dwc's Profile: http://forums.slimdevices.com/member.php?userid=1892 View this thread: http://forums.slimdevices.com/showthread.php?t=22502 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
