Next DSD firmware update in 2020 or 2021?

You can run DSD512 via USB with just the latest Stream Length drivers. You will need to compile them yourself. I am not saying anything more about this.

Tedā€™s right. The chassis is so different that it makes it nearly impossible to do any kind of ā€œupgrade kit.ā€ Nothing much has been discussed, but Iā€™m sure weā€™ll do a generous trade-up from DSD to TSS.

jamesh : can I assume this trade-up would include Canadian DSD owners?

Most of our distros do participate in some kind of trade-in/trade-up program, but I canā€™t guarantee it. I have no say nor control over their markets.

No, not really. From a purely pragmatic level even simply having multiple FPGA releases available to choose from isnā€™t possible in the DS: the memory that holds the FPGA code was stolen from the graphics storage memory and the PWD only had so much memory. So a change in hardware would be required for multiple choices.

Even with more hardware the best we could do in practice is simply choosing one FPGA release or another.

There is no concept of this from one release and that from another. The FPGA code is one big blob of hardware interconnections. No piece from one release is separable from the rest of the release.

Differing releases arenā€™t designed based on subjective assessments of sound quality. On the other hand a given release is built 20 ways and one of those is chosen by careful listening.

I choose a place or places in the code to make things technically better, e.g. fix a bug, use more precision, use a new algoā€¦ I usually also try to find some more places in the code to lower the noise generated in the FPGA. The net result is each release more accurately delivers the audio described by the input bits.

So the effective difference in the source code is that over time there are more refined algoā€™s, fewer bugs, and more carefully chosen use of the resources available.

Now, itā€™s always the case that some people will prefer one release over another, the idiosyncrasies of one release or another might have more synergy with the rest of a given system or user preferences.

Thanks Ted

The PS Audio has been known to be ā€œ smootherā€, less dynamic and more rolled off than most other dacs. Iā€™m hoping to see something that moves away from the smooth and more to the dynamic side. What Is the TCC I see spoken about above? A new model coming out?

The TSS stands for Ted Smith Signature. It is a forthcoming DAC from Ted. You can read all about it in this thread. TSS Two Chassis Super DAC

Whatā€™s great about the DSD is that it is smoothā€¦but it is not rolled off or less dynamic. It provides great detail and resolution too. The frequency response measures quite flat.

Totally agree. DSS is a perfect balance of all these, especially in this price point.

First, welcome to the community.

Regarding the quote: Says who/ā€œhas been known to beā€ by whom?

This is an awfully broad/sweeping statement to make. No ill-will intended to you personally, but I canā€™t help but respond and note that there are people on this forum that have never heard the DS Sr. (in any firmware incarnation) and if they were to be considering auditioning or buying one, your statement would be very off-putting (especially the so far unsubstantiated ā€œthan most other dacsā€ declaration).

So, if you have any support for such a claim (including your listening experience, published reviews, comparisons to most other dacs, published objective testing results, etc.), I think that would be helpful for potential purchasers.

That said, subjectivity and individual preferences are at the heart of our passion for music and kit and it is perfectly acceptable for you to hold this opinion, personally.

Kinda reminds me of the phrase weā€™re hearing on the news all the time; ā€œmany people are saying.ā€

I wouldnā€™t mind having capability to decode high sampling rate files properly. However I definitely agree that most of good sound quality albums donā€™t necessarily have to be high rate sampling. What matters most depends on the recording quality itself rather than the sampling rates.

exactly, same here

I find it fascinating the difference good mastering makes. Take the Patricia Barber album Cafe Blue, to me, the mastered version is far better than the unmastered version that was released a few years ago. Having said that, Iā€™ve no idea how important it was that the basic recorded tracks were of a particular standard.

While recording quality is imperative, the mastering is really the most important part of the process by far. A poor mastering can ruin an otherwise great recording while a great mastering can make even a less than stellar recording sound pretty darn good.

Generally speaking, this has been my experience as well. And, when you here great music that is of superior production/recording quality, you KNOW it!

Cheers.

I think that was true back in the 60s or 70s when he coined it, but Iā€™m not so sure it applies today.
