...my Microsoft Word docs have never sounded better on this fully-optimized network.
Emile, my bad. Sorry I used the wrong word "daisy-chain" (b/c I had no tech knowledge). My "translation" went wayward. The two guys PARALLELLED chips (in their case the vintage Philips R2R chip). The paralleling of chips vastly reduced noise (SERIAL wiring, or daisy-chaining, would greatly increase noise). I talked to the guy who paralleled 8 chips. He said that such paralleling would work only with chips that use current, not voltage. Hope you experimented with the proper paralleling way (that also requires proper power regulation). If you did serial wiring, could you experiment again? I'll discuss with the other, more advanced, guy who currently paralleled 36 chips (and will eventually do 48 chips or so based on his computation). One reported "night-and-day" improvement; the other very significant improvement. Understand that their way of paralleling so many chips would be commercially unviable; they did to their own self-made carbon-battery-powered DACs for themselves. They would not have kept paralleling unless they heard huge improvement. Thanks anyway for your open-mindedness.Done and discarded, nothing works as expected in an environment where even nV or fA increases in noise are very audible.
My Modwright modified Sony SCD-777ES player back in 2004 or so had several paralleled and stacked DAC chips. Definitely not a new thingThis is in essence how the Aries Cerat DACs are designed by paralleling 16 R2R ICs (the Analogue Devices AD1865N-K). It’s a hugely heavy DAC, weighs as much as the Olympus (130 pounds).
It boggles my mind the lengths to which high end audio designers are going in the world of digital.
Or is the Olympus to be viewed as a battery-powered Roon endpoint?

EmileNo worries, I assumed you meant paralleled.
In the Olympus/XDMI environment we appear to have to reinvent everything. Every single component matters, significantly.
Can I get out of delving into the benefits vs drawbacks of paralleling DACs by just going with the following? :
In the “V2” (RCA) analogue stage we’ve so far reduced the component count from 100 to 70 while adding a second DAC chip turns that 70 into 108. The 70 components version sounds better then the 108 components version.
Emile
Can you tell us of those parts removed, how many were dedicated to the connections between v1 and daughter board?
If not, can you comment on the effect of removing those connections on the overall sound in v2?
Marc
My take away is you're suggesting the v2 is a daughter board.I think not one part is removed which was dedicated to the connections between v1 and daughter board.
Btw the connection is very well chosen and has an extremely low resistance and has a good reason to be there.
I think what Emile is saying that with our (Taiko) approach it is to use as less components as possible. (With more parallel dacs/chips you need more parts.) And every part/component is audible.
The Olympus/XDMI is developed to shortcut the most possible, to bypass all kind of conversions to 'normal standards'. With as a result a very clean environment. Even more helped with everything battery powered. In this ultra clean environment you can hear every component what is used.
...I plugged in "Default" based on someone's guidance at the time, and left it alone. That was great at that time.
Having never used Roon before, I had no relationship to the DDC manual guidance re: Roon vs. XDMS and filter selection.
But, I moved the DDC output cable to Alt2, per above. I am not sure how much this workflow has to "burn-in" since it was never used, but I would say initially, this would be a better sonic choice in this system.
Emile, I appreciate you mentioning the filter choices. In this system, the Alt2 option provides a bit more sonic meat. I do not find any loss of detail or speed/pace. But the sound is not so sharp or hygienic in nature.
I should still probably putter around with the speaker toe-in, which is minimal here, to see what's up, but I will let things settle for another week or so. Multiple changes usually end up being confusing to sort out.
It will be interesting to hear about other MSB users and their options and opinions.
Thanks again, Emile. Happy New Year and Happy Listening to all.
I have certainly gotten the impression that the Wadax Server/DAC combination has also achieved this feat a few years back now. It does seem to be a feat, and I'm glad that Taiko has done so, as the Roon UI is pretty desirable. I'm looking forward to experiencing this myself, hopefully soon.One of the standout features of the Olympus, and not a minor one, is its ability to run Roon (which is very resource-intensive) without impacting sound quality.
I am not aware of any other server/streamer capable of achieving this feat.
My take away is you're suggesting the v2 is a daughter board.
If Taiko is trying to remove any and all bottlenecks -
is there a possibility that a dedicated xdmi analog card without well chosen bits (the connection between main board and the daughter board) be better?

I find this illuminating especially the DCD aspect. I don't have the Olympus yet so I wouldn't want to wrap my ears and brain around anything more until the O arrives...Remember that each DCD output requires its own burn in period, so patience on final tweaking.
That being said, I was very surprised how much of a difference the different dcd outputs had to each of the switch and router. Some combos were too much of a good thing, others were relaxed bliss
As I changed the energizing power supply, my preference changed as well. I have a couple new energizing supplies coming through over the next couple months and looking g forward to hearing g the impact (the effect of power on the network side was quite sigbificant…enough the persuade me to order an I/O and bring more BPS’s to the party)
DCD is a chance to do “filter rolling”, so good to have all the outputs burned in before making final decisions, but the character of the different filters is very easy to hear here.
