Was Upcoming DS release - Now Windom has been released

You know when I posted this I didn’t think about people thinking I received one from PSA. No it is blank awaiting download.

You are a tease.

Maybe the files are just hidden until the release date :wink:

I’m curious why you bought a SD card from PS Audio? Did you not receive a 2GB with your DS?

I’ve used the same card for all releases, I just create a folder for each release and copy the one I want to run to the root of the card and reboot.


No. I got it at Best Buy. I have just made it a habit to get a new one on each release. I’m a computer guy too. Haha. You think I would just use logic and not give into gremlins.

September is a few days away.

Any progress as to when the new update will be?

Hi @tedsmith

Regarding the quoted.

Since your D to A is discrete design why can’t you design this crossover to be at this optimal 1 bit sample rate that you mentioned (between DSD128 and DSD256 rates)?

Is it because those people paying for DSD256 music would be upset their music is being downsampled to something between DSD128 and DSD256 rates?

A bit like the thing you mentioned about supporting DSD512 input.

By crossover I meant the place where the curve showing the increasing S/N from having more resolution from more samples as the sample rate rises intersects the curve showing the decreasing S/N from jitter as the sample rate rises. These curves are based on idealized devices and almost certainly are worse for any real device. The point is that even in theory as the sample rate rises the additional S/N from more samples is swamped by the increased noise from more jitter at some point and that point is somewhere between double rate DSD and quad rate DSD.

Thanks @tedsmith but that’s what I was asking. Why do the conversion to analogue from DSD256? Why not somewhere between DSD128 and DSD256 rates? Since you can use discrete design.

Sorry I misunderstood.

Tho theoretically one can do a fixed synchronous sample rate conversion between any two frequencies as soon as the ratios aren’t a simple multiples (or divisors) the work gets more complicated and we can hear it when we need to use more resources in the FPGA to get a job done.

The optimal sample rate/jitter point is fairly flat, overshooting or undershooting by an octave won’t make a big difference.

At a more pragmatic level the clock jitter mostly depends on, well, the clock. There are only certain frequencies available and as you go higher in frequency the phase noise gets worse. I got the lowest phase noise I could get that would do the job. Trying to convert to some non multiple of DSD64 would necessitate a worse clock (or a heck of a lot more money for a custom clock.)

Love to launch in October and that’s currently the plan. Sorry for the wait.


A post was merged into an existing topic: Bridge II update?

Ah yes, I forgot about how simple multiples can help. I should know even from using HQPlayer that “auto family base rate” enabled is always less CPU intensive. This setting keeps an integer multiple of the 44.1k and 48k base rates and keeps CPU loading lower than trying to convert to multiple of other base rate.

Silly question from me. All clear now. Thanks @tedsmith

Sometime ago Ted had mentioned that he had new DSS Firmware in the works. I was wondering if this has come to fruition yet and I missed it? If not, what might the timeline be? Now that he has figured out a lot more due to the advent of the TSS I greatly anticipate This! Thank you

There’s a firmware update for the DS DAC in the works, hasn’t been released yet. Possibly October, we heard.

@Paul Our company (which is in semiconductor business) is launching a new product line on October 8th! Let’s synchronize launches. :wink:

Rumor has it one should anticipate an October release of Windom.
Corrected spelling.

From Wikipedia:

Windom Peak is the highest summit of the Needle Mountains range of the Rocky Mountains of North America. The prominent 14,093-foot (4,296 m) fourteener is located in the Weminuche Wilderness of San Juan National Forest, 28.2 miles (45.4 km) northeast by north (bearing 32°) of the City of Durango in La Plata County, Colorado, United States. The summit of Windom Peak is the highest point in La Plata County and the entire San Juan River drainage basin.[1][2] The mountain was named in honor of Minnesota senator William Windom.

I don’t know…digital yeti was just in town…maybe with a yeti gift…

This is a fine example of why Ted does what he does and the rest of us do other things

My upmost compliment to you sir!


Thank you Ted. I cannot wait for this. I am guessing with what you have figured out, this will be the biggest leap for the DSS yet. At this point it very well may be the finest DAC for all but the most defining Audiophile. Moreover I am fully elated that you are still supporting it this far out. Few companies would. We certainly got our monies worth IMO.
