do you mean when you say "playing in " burn in ? if so then both cable and the electronics will change to a greater or lesser degree over time.
The toslink connections in my experience tend to be inferior to a good digital coax ...I add good as there is some really nasty ones out there. If your running the standard psu for the sb3 then I would expect the dvd as a transport only to have the edge....if you have a good psu the sb3 should be ahead of the dvd both into the dac. The beresford dac are good at there price point but not the last word I have a behringer src that in standard guise was able to see off the beresford [early mk] without difficulty ...I've since modded the unit and it showed a clean pair of heals to dac1. The flat sound your getting, sound like what I had before I upgraded the psu for the sb3 ...for me it was lifeless and uninvolving. Also the beresford can use a better psu too and the early mk version sounded a lot better with a few simple mods ...better caps, schottky diodes and better opamps. I have no experience of the more recent models but if the maker has taken any account of the mods usually carried out on this dac then it should sound a whole lot better than the one I heard. -- zanash Acoustician and builder of interesting cables ------------------------------------------------------------------------ zanash's Profile: http://forums.slimdevices.com/member.php?userid=12157 View this thread: http://forums.slimdevices.com/showthread.php?t=37720 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
