I'd like to share some preliminary findings to see if someone else wan't to give it a try and perhaps become as astonished as myself.
What I use: An SB3 A TacT RCS 2.2x pre-amp and room correction unit An Krell FPB200 power amp Yamaha NS2000 speakers A Yamaha surround processor for A/V use Home made interconnects and speaker cables. The SB3 is connected to the TacT via a coax SPDIF. I have had the A/V processor hooked up to one of the TacT's analog inputs most of the time. Weeks ago I was experimenting with disabling analog out on the SB3 to see if it affected digital sound quality. To verify that analog out was turned off I connected the SB3's analog outputs to the TacT's analog inputs, simultaneously with the digital. This didn't seem to affect the digital input quality. Recently I disconnected the A/V system, which uses very long interconnects. I was astonished by the improvement in sound quality from the SB3 (on digital input). In addition it surprised me as previously disconnecting the A/V section had a more subtle influence. Today I removed the analog interconnects between the SB3 and the TacT, and lo and behold, sound quality on the digital input deteriated massively! (To something which is more like I'm used to with 16/44 playback.) I put the non-used analog interconnects back, and sound quality again improved. My initial guess is that running multiple ground paths alters the ground reference noise available at the SPDIF receiver and/or transmitter. My two analog interconnects are home made, and use massive ground conductors. My digital interconnect is a mid price commercial cable. If you use an SB3 with a TacT RCS you might want to try this unexpected tweak! It transformed my SB3-sound totally into something I used to only relate to good LP playback. I'd be most interested to hear if anyone else (presumably a TacT user) can reproduce this fenomenon. -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=28307 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
