has anyone tried PS Audio perfect wave duo

In addition to it apparently being compatible with some emerging high res formats, I gleaned that the novel feature here is that data is cached in memory with this setup rather than read live direct from the optical CD disc as is done with most players and this is an affective approach for minimizing jitter.

Network players like Roku SOundbridge ($200) and Logitech Squeezebox have been doing this for several years now and are another cost effective way to get this benefit if you are willing to go the music server route. For best sound, just use these with the external high quality DAC of your choice.

I believe I saw PS Audio will offer a similar network player as an alternative to the transport at some point.

Some other resampling DACs, like the Benchmark, are also designed to effectively minimize jitter on board the DAC as well.

A friend has had his for almost a month. It's very nice as-is while he's waiting for the debut of the "Bridge" which will enable him to use his modded SB(He wants to get away from discs altogether).

I don't get it.... This unit has a one disc memory and plays the disc from memory, not directly from the disc.
In effect, this is a one disc music server.
Am I missing something or is this just the ultimate in audiophile marketing hype?

I think it has some smart out of the box design features that should lead to good sound.

Nothing you can't get elsewhere for lower cost I think but those routes currently will probably generally require more effort and knowledge on the part of the user to get right.

Also I am not fond of products that require bridges in general, unless absolutely essential. This is usually an indicator that proprietary approaches are being used that may produce very good results but limit options in terms of integrating with other vendors products. That usually end up meaning you pay more for what you get from that particular vendor.

The combination is truly excellent to a degree that all of the aforementioned devices/DACs pale by comparison (yes, I have heard the aforementioned servers and Dacs - PS Audio-DLIII, Benchmark - DAC 1/pre, Cambridge-DAC Magic, ARC-CD7, Wadia devices, SB3/Duet/Transporter, etc.). I do not have any experience with the acknowledged digital leaders (i.e.: MBL, dSC, and other five-figure devices), but I can verify that the Perfect Wave combination indeed takes digital to a new level.

Wpines - the PWD will allow full server capabilities once the Bridge device is released later this year. Most high-end transports these days are designed for single disc operation. The key to the Perfect Wave Transport is the built-in Digital Lens, along with the true I2S interface. Combined, these two technologies allow, among other things, exceptional jitter control (i.e.: reduction). The PWT also supports up to 24/192 native. The forthcoming Bridge will also feature a "built-in" Digital Lens and I2S interface. The big deal is, it is a true high-end solution to music servers (which is the only way to go for digital, because HD SR files absolutely convey more information than the limited (and “old”) Redbook format (16/44). Finally, digital is becoming a nice alternative to analog.
