PS Audio unveils their PS Audio Directstream DAC


First of all I have no affiliation with PS Audio, just an interested observer.

PS Audio has just announced their successor to the Perfectwave MKII called the Directstream DAC. It implements DSD and eliminates the PCM delivery system and uses a Field Programmable Gateway to acheive results which they say will "uncover more music on redbook CDs than was possible.

A full explanation can be read here:

Jon2020,

That's not the way it works. There is no such thing as an instant install of all versions simultaneously -- and an instant comparison switch. You need to use an SD card for each version and reboot each time.
Wisnon,
Yes, I meant firmware rolling.

Sabai,
I get that reboot is required for each firmware version. That's why it would be great if you could change each FPGA version as a setting option on the fly without the reboot. I guess that may be hoping for too much. Maybe someday, the folks at PS may come up with something. After all, it is just software. So, instead of a firmware reboot, it could just be an FPGA setting option. The PS team would certainly want the DS to be all things to all people and that would indeed make it a topseller.
Cheers! J.
Jon, i know, just teasing.

I am in the loop for the DS, as AL and Mike keep me up to date and I also read TedB.

Apart from the reboot, you have to wait 10-30 minutes for the Dac to degauss and sound good again (transformer outputs). I think they cant do the instant rolling like you wish for as the FPGA does not have enough memory to hold the additional FWs.
DS owner, here.

Maintaining multiple versions has been discussed at PS Audio's forum, as a "wouldn't it be nice." Ted Smith, the designer of the DAC, has said that it would be very difficult to do multiple versions due to a lack of... something... probably memory. Perhaps two could be maintained, at best.

Considering the improvements that I've heard over a couple of versions of firmware, I have no problem inserting an SD card, waiting 2-3 minutes, and listening. It's a bit more difficult to A/B, but the differences are usually so clear that it doesn't take long to make a decision on which FW version you'd like to settle.
Jon2020,

I think that's asking way too much -- in the realm of wishful thinking, for now.
