Nope, I2S is 9 pin D-SUB port (like console/COM port on PC).

There were many type connectors for I2S signal, like North Star they use network connectors.

With my understand, I2S is more clean digital signal.

You may saw they with CDPRO2 modules.

I'll get the chassis from Novas, will finish my DAC1794.

 

[Cronstead]

Thanks for the info. Much appreciate.


The chasis is awesome, from my estimation the used plate is about 50mm thick!

Thanks for correcting, I was confused because I read a few threads mentionning that USB implementation of current DACs did not use I2S tech so..
Did you try the I2S connection?
Anyway, I m eaerly awaiting some impressions

 

[palchiu]

That's possible!!! I've bought a USB receiver before(Also design from Taiwan, By a-jen), they can transfer I2S signal.

If put the usb receiver in the dac, could be use USB with DAC 1794.

 

[JJ15k]

WHat do you mean "If put the usb receiver in the dac, could be use USB with DAC 1794".
Is there a special addon for usb?
thanks

 

[Cronstead]

It is not something that comes with DAC1794. It is a usb module from other Taiwanese DIYer. But since DAC1794 can also come as a diy kit, you could add it in.

Here we go! http://bbs.audiohall.net/viewtopic.php?t=1162&start=0

This USB receiver can provide I2S out, then DAC1794 receives I2S signal.

This is the way to do. (Sorry, I didn't put them together. But it works with Shark DAC, Shark can receive I2S signal.)(DAC 1794 and the USB was not the same designer.)

Why USB only? you may use sound card's digi-out, and connect to DAC.

 

[JJ15k]

USB is not necessary, would just have been a nice option.

Well Cronstead

When are we going to find out what this bad boy sounds like?You don't say where u live at ,but if your in usa,ga i could swing by for a listen

 

[Cronstead]

Sorry for the delayed, I've been enjoying the system too much.

This is what I found so far:

It's very detailed, HF are very refined - no sibilance nor edginess, the bass is also very good - goes deep down and impactfull, soundstage goes wide and deep - not just on x and y axis but fills gaps between x and y axis as well, and sound separation is darn good.

For example, listening to Dadawa's Sister Drum, in particular the tifas and "Tibetians' trumpet", will literally shake your head with very low bass (the trumpet) or very impat bass (the tifas)!

While listening to The Corrs, the instruments are located and separated nicely. It seems very accurate to me (I know it because the audio was demuxed from the DVD - The Corrs MTV Unplugged). The strings (guitars, violins), vocals, percusions are nicely defined and sound very real to me.

Overall, it is a very musical product, and well balanced through out the frequencies.

But please don't take it as final judgement yet, as the RCA that I'm using between DAC and my amp is Furutech SA-162, which I believe it's the bottleneck in the system. And since all this stuffs are very subjective (as we all know), so please take it with grain, and salt and remember YMMV!

Btw, the system is: Emu 1212m->DAC1794->GS1->HD650 with Blue Dragon V2/K701.

 

[JJ15k]

What do you think of the highs/mids with the K701? I have a K1000 so bass is less important for me

 

[Cronstead]

Highs and mids are very good to my ears.

[Cronstead]

Well, it's weekend and I'm bored ... so I played around with the RMAA using my emu 1212m and the DAC (single ended mode):
http://www.users.on.net/~ehendriks/d.../DAC1794-3.htm

Problem is ... I don't really know what the results mean. All I know is that the Excellent marks make me happy.

Could someone chime in and give me more explaination on the graph?

 

[bizkid]

Wow those measurements look very nice!!!

I want that DAC too
