PS Audio PerfectWave DAC Upgrade

Paul McGowan has leaked some information about a major upgrade the perfectwave DAC that will be coming out within the next few weeks. Pricing as of yet unknown, but current units will be field (DIY) upgradable.

Apparently, major changes were made to the digital processing board, involving changes in the powersupplies, and replacement of CMOS switching for the gates and clocking with analog switches.

Second, new jitter reducing circuitry called NativeX was implemented.

There are more as of yet unannounced new features.

Apparently, SQ on all inputs will benefit, including the bridge. Exciting stuff.

"Are you saying that Steve is using PSA's I2S offering it as an option?"

It's not an option. Standard on the OR5.

"I wonder if my Pace-Car can be modded with the same?"

Sorry, but no. HDMI I2S is a completely different electrical interface.

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.

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.
