PS Audio unveils their PS Audio Directstream DAC

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.

If it is purely a memory issue, then it may not take too long. RAM chips are getting faster and cheaper by the day. But for now, we'll just make the best of it. It's very interesting to note that opinions of PP vs 1.2.1 can be so divergent.

No Jon,

It has to be on the FPGA and that seems to be maxxed out.

To use a bigger xylinx chip would require a complete redesign of most everything.
