Totaldac thread, d1 core / single / tube / six / unity / direct / twelve / digital / streamer

I dont use the streamer part and cant realy compare to others in the same price range. I like it, but ite a shit ton of money and i just have no idea how it actualy stacks up for the price unfortunately :confused:

Thanks

Gotcha, so you connect your computer to the box to use the reclocker function, then output to the DAC?

Correct

I have been digging around and the streamer board looks to be based off a Cubox which fits the metal enclosure on the left side of this pic:

And the I/O is the same except upside down:

Not familiar with this, imagine it is something like a Rpi, obviously there is more to the overall build than just this box like software and other components used to run the streamer functionality, might explain why there is a need to use a USB cable on the exterior to connect?

There probably isn’t that much more to it. That’s a full blown PC not a Pi and the shield and external USB is to minimize noise inside. The second best way to keep noise from getting inside is to shield the hell out of it if it needs to be inside. Looking at that pic, that’s 90% reclocker and 10% streamer!

Definitely would LOVE to hear your thoughts on it when you get it!

So I got a chance to get the d1-twelve-mk3 and d1-streamer-mk2 measured this weekend. Not as bad as I expected in terms of sinad (I had requested we fudge the numbers to get 69dB cause I’m a child but we were too far off), but I did find that my two channels were out of phase (amount changed every time sample rate did, but stayed around 8-9 microseconds with the right channel behind regardless of sample rate of frequency). I emailed vincent to see if he has any ideas, but I do wonder if its the clock sync cable. Also found out that the streamer was pretty good at rejecting jitter but worse in terms of phase noise which I found interesting (wonder if that contributes to the more natural stage maybe?). Also got to check the OI and found out that its 2000 ohms which is pretty wild and absolutely explains the amp pickiness.

Well that’s a definite answer to say it’s direct out without an output stage lol

That’s what I would have figured as well, somewhere 70s

Could be why the clock cable could be drastic sound changes in some cases

IIRC we were at ~83 dB (ill get the report later and post it here) which is right about where a WD edition is at. This is also only with 48 hours or so of warm up.

Yah, ill see what Vincent says. TBH I’ve had issues with my left ear being more fatigue sensitive than my right for a while now and while I do think it started before TD, I am now second guessing myself on that one. Ill try swapping left and right channels in software and then swapping the cables so that everything is right way around and see if the sensitivity moves to my right ear once I get it all set back up tomorrow.

As for the clock cable, I am using what I am fairly sure is the stock cable, but its like 8" long which ive always been a little concerned by. Ill try some other ones for sure, but apparently I dont realy know what to listen for to identify the phase shift so I’ll have to play around a bit.

Oh that’s better than I’d have expected then

Would be very interesting if that was the culprit

Seems like a largish discrepancy, it’s < 1 audio sample at most frequencies, but I’d expect better.

I’d assume you’d get some phase difference but it ought to be less than one clock of the external clock, and that’s closer to 100 clock ticks assuming it’s a 10MHz world clock.
I mean it ought to be able to manage that sort of discrepancy if the external clock was entirely disconnected, and it was just sharing a SPDIF cable.
Could be a bad cable.

Is Usb good with Total dacs compared to their Aes? Also SE and Xlr.

I thought the built in streamer in mine which connects via USB was good.
Better than the AES sources I currently have, pi2AES, I don’t have a really good AES source lying around anymore, but I know @M0N preferred his via AES.

I use both the USB and AES inputs on mine. For full transparency, they are sourced from two completely different devices.

USB < FTA Sinope < Sonore UltraRendu < Cat6A ethernet < Intel NUC w/ROCK

AES < Tara Labs RSC Prime M < Singxer SU-6 < AQ Forest USB < PC

The USB is my input for when I want to just listen to music. I’ve used the AES input, and there is a quality drop-off that comes from the lower quality front-end. Unfortunately, I don’t really have a way to test both the USB and AES from a quality source. But using the USB isn’t something I would be worried about.

Fwiw, a dealer I know uses AES on his totl TD system back when he had it (now sold).

Without similar sources and cables this is really hard to answer

AES is the best input on all td DACs, according to Vincent. From my experience I can verify this too. I also have the built in streamer card feeding its USB with the Uber-expensive gigaUSB cable and AES beat it out without a sweat. This is coming from a Pi2AES too!

It’s not just the input. The AES output of the source has a lot to do with it IMO. I recall when I had the Pi2AES that was clearly better on AES out. I think some DACs may be equal in input comparing Coax SPDI and AES but the source can lean it one way or another.

It’s also rare when people have the opportunity to test apples to apples cables. Usually when making comparisons people have different flavor cables so as @orrman it’s hard to answer anything like this definitively. I’d tend to go by the vendor’s experience and recommendation.

That’s why I have a testing kit - Audioquest Carbon I2S, USB and AES cables lol

Well I got your counter-argument ready to go, I have identical Boomslang digital cable in AES and Coax, so both were fed simultaneously from the Pi2AES. Though that has no impact on the original question posed by @M.J

Hi Totaldac fanboys :wink:

Even I thought I stop the DAC-battle, I couldnt resist, because many Totaldac owners here in EU are currently selling for really good deals.

I just purchased my TotalDAC Twelve mk-I +bassboost for my second hifi chain…let’s see, finally an R2R in my house.

Curious if anyone here has the older model and upgraded to mkII/mkII.

THX for sharing!
