PS Audio PerfectWave DAC Upgrade

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.

Would certainly be interested in the results, if you get around to it.

Mrtennis: The most noticeable improvements of the MK2 board are bass and soundstage. That is what I noticed in a before/after comparison, not side by side. I will say that I find well-recorded CDs to sound more dialed in, immediate, and absorbing. So, it is likely that more changed than bass and soundstage. Even my wife, who takes little interest in audio, has commented on how the sound quality has improved. (I use the Transport with an HDMI cable, and haven't experimented with other digital connections.)
