Some details on here if your into diy for the clock http://theartofsound.net/forum/showthread.php?t=6499 for the psu http://theartofsound.net/forum/showthread.php?t=3161 , socket and bybee http://theartofsound.net/forum/showthread.php?t=5669
If your not into diy Mark at Audiocom is your man to speak to ,he's also a member on here, the Duet responds extremely well indeed to mods , if your not bothered about hi-res a fettled Duet takes some beating for the price.
Certainly ditch supplied SMPS, its pretty poor tbh
Cheers for the info Leo...
