Taller Mountain : PS Audio DirectStream Windom update

What’s it all about?

Having a DAC that has firmware upgradeable software is a big bonus which is allowed with FPGA (Field Programmable Gate Array) DACs for they programme code into the system. Not like normal DACs which have no such flexibility.

Something that is happening when you turn it on is the giveaway….The initialising screen. A similar thing is going on with other brands of FPGA DACs except that PS Audio are I think, unique in offering a user upgradeable firmware service. In fact PS Audio put a lot of effort into doing this, led by chief designer Ted Smith. And it’s a FREE service too.

It not only keeps audiophiles interested in their audio and DirectStream but is a selling point for PS Audio too. No more are tone controls on amps that much but like salt and shake crisps there is no problem. Just choose your own flavour and stick to it, akin to that old firmware update, or change to new flavours as they come out. In this case Windom. The old version was Snowmass, all smartly named after mountains in the Rockies.

How have things changed?

Like the shrink who wants to form their own view with no interference no doubt, I didn’t read any of the reviews or marketing spiel before I set out to check myself. No bias here buster!!??

First off I noticed a slight reduction in the edginess of the treble changing from Snowmass to Windom.

What also strikes you too is a widening of the soundstage with Windom and a slightly more rounded quality to the sound. Snowmass is slightly narrower in its projected ‘field of vision’.

These are subtle to big differences depending on your perception of living with HiFi. Have little time with the DirectStream and it is subtle, as I initially thought, because you aren’t used to the house flavour. But keep eating those crisps (or listening) and you know what the changes do and they are more profound! A big issue in gauging audio quality, but often maligned on online forums.

PS Audio say in the press release ;

“Windom reveals richness and natural detail within the music at levels formerly unattainable in any digital to analog converter we have auditioned. With its improved retrieval of reverb and ambience, Windom communicates with a glorious sense of openness and effortlessness, adding a sense of immediacy and ‘rightness’ without sacrificing honesty or transparency.” AND

“While developing the architecture of his ultimate DAC, the Ted Smith Signature DAC (TSS), Ted learned ways of moving functions from noisier FPGA resources to quieter ones, and restructuring memory allocations. The result is an even lower digital noise-floor with these benefits:

  • Playback at high volume levels is clearer and cleaner than ever before;
  • Soundstage is even better-defined due to increased channel separation and lower noise, providing a clearer, deeper image of hall acoustics and decay times;
  • Overall “sound picture” is more 3-D, more realistic;
  • Bass is significantly more impactful and better-defined than with any previous OS.”

I’ve highlighted the bits I’ve found and it goes to show there is no BS in these updates at all….. Very worthwhile and you can download the files from the PS Audio website here. Make sure you extract the raw files, not zipped up. There should be 5 of them!

I'm an AUDIO-LOVER who likes sharing experiences of faithfully reproduced audio in a CREDIBLE way. I am primarily interested in products; their looks, functionality and features, and most importantly how they sound! My reviews are not overly technical and I don't use pretentious language, as I believe great audio is non exclusive and is to be enjoyed by all! It's all about the music!
