dCS Scarlatti vs Wadia 931+921
I want to know what the differences in sounds are between those two ?
Please reply only if you heard both !
karajan
Asuming both are equal; while you're thinking or searching put also another question to yourself; which one has more reliable transport and is upgreadable through the years.

Such investment IMHO must be future-proof, reliable, with long warranty and of course a breath away if not already in from "computer-audio" & HDaudio 24/88.2 24/96 24/176.4 24/192 which will be the standard
Even comparisons with the Wadia 922 would be interesting. This would be the ultimate shootout! Please, anybody has compared either..even with other high end DACs such as Meridian... I would also like to know.
