I am confused by some of the things that I have heard about the Super DAC. One Big thing is Two chassis one analog and one digital. I find that very interesting as in all actuality there is no Analog stage in the Direcstream DAC. What it outputs is the result of filtering the digital wave produce…

[image] tedsmith: The sync bit is actually a direct sample of the first bit of each chunk in the down coming bit stream (no logic required.) The digital box can look at this return bit to see that it’s as random as possible which ironically means things are synced up. (If the bits are all the sa…

[Answering your questions in order, there will be some redundancy/overlap…]: The transition between the zero marker on the end of the last chunk and the one marker on the beginning of the next (current) chunk means that we know what to expect for about two bit times. Ideally that transition is exa…

Got it, thanks! Though my mind is a little blown by the last part about the frame alignment just finding itself. Will keep pondering that one :slight_smile: Edit: Oh!! If the bit being sampled is random (like DSD) then the digital box clock will stay exactly as it is and the alignment will drift to…

The key is to make sure that your data never has two bits in a row that are a zero followed by a one. (If they were always zero and one, why are you sending them…) So if things look locked but aren’t then there will be some change in the bits in the presumed zero/one transition. Then you just hav…

I had already implemented something similar in ECL for the first design when I encountered a SERDES chip that had the right payload size and rate that would work. I’m not usually one to forgo an interesting project, but debugging and fixing ECL running at a such a rate while writing the software to…

I haven’t perused all 970 posts, but even if I had I doubt the answer is still the same as one in 2018, 2019, etc. Ted, or anybody who has heard this and the DSD Mk II, how does the two-chassis design change the sound qualities vs the Mk II? Is it a subtle difference or more significant? Is it mo…

I haven’t listened to them side by side and I’m incorporating all of the Mk II tricks that I’ve learned into the TSS design. There’s a sense of ease that the TSS has that first struck me. Also instrument tones are a little more realistic. Having the digital separate from the analog also gives a b…

In your usual understatement that’s what it’s all about! I bet the TSS gets a killer.

That’s what I admire about you and why I read all of your posts, it’s devoid of phoney rhetoric.

There are times when it’s good to avoid making a wheel. There’s lots of good wheels available.
