I've had a Sigma since it came out and have never had any
trouble.
I have done a lot of mods to it:power supply,
caps and resistors in the signal path,bypassed
the toslink/coax switch, upgraded the 12ax7 and
other active parts.
I tried other DACs, DVD-A and CD/SACD players, and my Delta/Sigma combo still sounds great on redbook CDs.
