Drubin - here is Jiminias post:

As for why, its simply differences in jitter magnitude and spectrum. Jitter is the #1 performance limiter in digital audio.

Thanks Steve, I had read that but somehow forgot that he covered all that ground. The one missing piece is Ethernet to the bridge. What's the jitter profile of that?

Drubin - one would have to open-up the PWD and measure this with much care. I have not done this. Even if I did and gave you the spectrum of jitter, what could you glean from that????

Noone has even correlated this kind of measurement with sound quality yet.

IMO, our best measurement tool is our ears. This is after all what we end-up using in this application. Its kind of like designing a software simulator for a car tire design. Helpful of course, but there is nothing like driving on the tires on an obstacle course and wet and snowy roads to find out if they are any good or not.

I don't really care about the jitter profile, Steve, I was just using your terminology. What I am curious about is the sound of Ethernet into the bridge compared to OR5 into I2S.

I own an OR5 and a PWD MKII with bridge, so I could do a shoot out. Problem is my system is configured to run through a processor using AEs/EBU so this would be a bit of a hassle. May be I'll get around to it some day.
