So, as you'll remember (or not :D ) I ditched the Monarchy upsampler between my transport (modded Teac T1) and DAC (Chord DAC64) as I felt it wasn't really adding anything and merely confusing things with not one but two digital cables in the equation.\r\n\r\nSo, now my mate who's trying out the NAD S300 integrated (separate thread) brought it here for a couple of days before he has to return it. Cracking amp btw but that's not the point of this thread :) Anyway, at first he was having trouble getting a similar kind of sound to the one he had at his place where he has a Meridian 507 as a transport for Chord DAC64 (same as mine) and Dynaudio Crafft speakers which aren't that dissimilar to my Dynaudio 1.3MkIIs. The sound was somehow hard and bright :confused:\r\n\r\nWell, he decided to try switching out my Apogee Wyde-Eye digital (RCA) cable for an Ixos XHD308 optical (TOSLink) cable as he was using a cheapo optical cable aswell (as per the recommendation of Rob Watts, the designer of the DAC64). Well blow me down if the sound wasn't transformed! All the brightness and hardness was gone and what was left was a gorgeous full sound full of life :eek:\r\n\r\nI was surprised because before I'd tried using the optical cable from the transport to the upsampler (when I still had it) and it was a downgrade.\r\n\r\nTo rule out the effect of the different amp we just switched back in my Arcam A22 and tried the same test, Ixos optical vs. Apogee RCA and there was no contest, the optical link was a clear winner and it's staying in my system.\r\n\r\nSo, WM, if you've heard the DAC64 sounding bright, try an optical cable ;) Will Omiga Audio see the "light" :D and be making an optical cable too? :MILD: (of course, for DAC64 owners only as in other DACs the benefits of the optical link are less clear).\r\n\r\nIn the last month I've gone from two digital cables totalling nearly £200 plus an upsampler that cost me £200 between my transport and DAC to an optical cable that cost me £25. A £375 saving and a big sonic improvement - I like it :cool:\r\n\r\nMichael.
