I like the sound and ease of connecting directly to the power amp. Just helped my son's friend with his first non-rack setup. A Touch, a GFA-555e, and Vandersteen Model 2Ce Signature II speakers. FLAC sounds great on his speakers and its about as simple as it gets. As for your Amp, I haven't used any of them. But depending on how the XLR to RCA is done, you could be asking for big time trouble. IMO one should never use RCA to XLR adapters, its the easiest way to damage equipment. With a build-in thing your describing, I would not use that either for fear of grounding something that shouldn't be. Its one thing is you have dual inputs and there is a selector switch for XLR or RCA. >From what your describing it might be auto sensing (hope its checking ground also) and maybe its a function of how high the SB3 Volume is set at when you turn the amp on. If you feel there are no grounding issues, I would try it with low SB3 volume then higher and see if there is a trigger point. Never do high first, start low and work your way up but I would not go past 50% volume without inline attenuators. This process may require turning the amp off each time depending on how auto-sensing works if that what it has. -- iPhone *iPhone* Media Room: Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, VeraStarr 6.4SE 6-channel Amp, Vandersteen Speakers: Quatro Wood Mains, VCC-5 Reference Center, four VSM-1 Signatures, Video: Runco RS 900 CineWide AutoScope 2.35:1, Vandersteen V2W Subwoofer Living Room: Duet, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Kitchen: Squeezebox BOOM Bedroom: Squeezebox BOOM Bathroom: Squeezebox Radio Ford Thunderbird: Duet, Mac Mini Ford Expedition: SB Touch, USB drive ------------------------------------------------------------------------ iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=81664 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
