External devices are NOT better than PCI devices. Bill
This is incorrect, as the quality if the device is dependent on the converters. While true the PCI card can process faster, if it had inferior converters to the compared FW card, then the quality of the FW card audio would be better.
I'm curious - were they recording in 192? If so, that may well have pushed the jitter problems so far outside of the audible spectrum that they were rendered moot.
The sessions were 24/44.1. Everything sounded great, no issues whatsoever.
