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:

Jon,

You mean firmware rolling as opposed to tube rolling?
On my Big7, I do similar to change the presentation, but I was told that with the DS, you should wait 10 mins after rolling so that the system degauses the output transformers (during playback) and then you hear the Dac at its best.

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.

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.
