FractalSound
Head-Fier
My iDSD Signature is delayed. So hopefully I'll still get my iCAN signature this week.FWIW: I’ve had the iDSD for a while and didn’t really believe that I would need the ican (no signature) Got a very good offer though and received the Ivan last week. Until now I am very happy, it simply takes the sound up a level. However, I think that if you buy both at the same time, you may have to pay more attention to appreciate any difference….
