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.

"Now, the DL2 has been cancelled once again for some other BS product. I don't have time for this kind of rubbish."

The some other BS product you are referring to is actually an implementation of the "lens" technology on a board, available as upgrade to the PWD. A far more cost effective implementation. The upshot is of course the whole lens project will get killed. Just get the PWD MkII. Must be painful for the very few that have been waiting for a lens MkII for 15 years.... All others are elated.

"Why do we need an audio product that works with the cloud?"

I presume by the "cloud" you mean your home network. The anser is because network streaming has some big usability advantages over USB. Of course, networking opens up a big can worms, which is why the project has had significant hichups. They should have offered an asynchronous USB option from the outset. The new "BS product" offers exactly this. Better late than never.

"Why offer an outlet with a nickel coating, tout it as the best, produce a gold-plated version, cancel both products and then offer two multi-kilo Power Plants with the inferior outlet?"

Who cares about the outlet. I'd be interested in a double blind test between units with nickel outlets and gold-plated outlets. The new powerplant products are miles ahead of the old 300W/600W spaceheater units, which is all that matters.
The analog switching improves all inputs "by desing".

It appears the NativeX dejittering circuit improves SQ on all inputs (including I2S) as well, which comes as a surprise to the engineers and Paul, I presume because there was not supposed to be any jitter left (at least not at audible levels) on these inputs.
Paul has mentioned it has been put on hold because of changing priorities. I also believe he mentioned that since the lens technology would be largely implemented in the PWD, its target audience would be non PWD users looking for a dejittering device (like the orginal genesis lens). Given this limitation and all the other development priories it is not a big stretch to infere the product will be shelfed indefinitely, but this is pure speculation.
There is an unconditional 30 day money back for the upgrade, even if you buy at the early adopter price of $800, so if you don't like it you can just send it back. In the absence of a 2nd PWD you are partially dependent on your sonic memory for the A/B comparison. However, the impact of the NativeX dejittering feature can be assessed in real-time because you can switch between native and nativeX mode.
They cut over to the new site. Keying in www.psaudio.com works just fine, but the discussion forum is not accessible.
Mr. Tennis, basing your purchase decision on an $800 upgrade with a full money back guarantee on "reports" from others, stikes me as misguided. Just get the upgrade, hear for yourself and send it back if you don't like it.
Funny, two years ago, before the bridge was released I was sceptical about the chances of succes of the bridge project and started inquiring with both Steve Nugent and Rick Cullen if they could build me a custom USB -> I2S interface using the PS Audio I2S interface - they were both very interested. I also asked PS audio if they would build this converter but they were so focused on the bridge architecture they declined (although they had already started doing work on this project but then ditched it). In any event, then the bridge was released and I dropped the USB -> I2S converter idea. Glad it to hear it came to fruition after all....
Mrtennis, for some the funds of the upgrade may be better applied towards a state of the art tennis racket. For the rest of us the upgrade is a no brainier. We are enjoying our upgrade every day, some of the best bang for the buck ever in high end audio. Cheers!
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.
Mcondon, PS audio is specifically positioning the DAC as a network steaming device. The ultimate goal is to get the bridge interface to sound as good as the PWT, which theoretically it should be capable of. I personally went from using the bridge to the AES/EBU interface (I inserted a Trinnov processor in the chain before the PWD MKII), and found the differences between the bridge (I2S) and AES/EBU minimal after the MKII upgrade.

I never fiddled with firmware versions myself, and I am hugely sceptical of assertions about a DAC you would not like with firmware 2.1.0 turning into an unbeatable giant killer DAC with firmware version 2.0.2, but that's just me.
Many of the ultra high end guys are demoing their five and six figure speakers at shows with computer based sources. If there was a compromise they would not do this. So if you don't cut any corners, you will get similar or better quality from a computer source than a CD player. This involves using a good CD ripping program, a dedicated music server, a high grade USB converter (unless you have a DAC with very good USB input), and a good USB cable (not without controversy this one).
