Hifimediy direct out cs4398 DAC

Olav,

Thanks for the explanation, and now I need to think about putting in the Sowter transformers too (some time in the future, if possible).

Hi Guys,

I have been using mine for some time, and it's great!!

I use COAX input, in NOS mode (Eg, with SRC module removed and jumpers installed)

But just recently I have tried feeding it 192Khz (via COAX) for the first time,, but this little DAC doenst seem to like it :-(

The LED on the input selector flashes/flickers.. Audio output is crackled and distorted.. Seems like the DAC cant "lock" on to the signal..??

From what I know,, this DAC should be able to receive 192KHz via COAX in NOS mode??

Thanks..
CM

Hi MurphyUHF10.

This got me thinking. I stream 24/192 from my Squeezbox Touch - but through the optical input. And the sound i really great.
But I experienced problem in pre-Christmas times - and it was when I changed to Coax for the input from Touch. Hmmm....
Makes me wonder if the Coax-input is not so good for 24/192 format-files and Redbook should go here.
And one should use optical for higher-bits files??
Wonder if someone from Hifimediy have a clue.....

I have been keeping straight to Coax for 16/44.1 and Optical for 24/48,24/96 and 24/192 since mine was running well again. And now it is SO nice and fully-funcional. A dream maskine!!

Hi MurphyUHF10!

Too early morning here... It is the other way round - I stream higher resolution files through the Coax - and keep 16/44.1 through the optical. It has been running like that for some time now - very stable!!
And it is also streaming 24/192 from the Touch(if touch don`t down-sample the files-and as the squeez-forum says it isn`t!) - the Coax should function with higher rates!

Best - and sorry for my wrong-info earlier!

Olav,

The Squeexebox touch by default, only supports up to 24/96.. Your 192 tracks are probably not 192, or, are being sampled down to 96 by the sbt.. But in standard form, it is only a 24/96 device I'm sure..

When you install the "EDO app" on the sbt, then it will output streams up to 192, via coax and USB,,, but not for Optical.. Actually, I think the bandwidth of Optical is limited and cannot go up to 192 by its very nature..

Thanks for the correction Olav.. Now I understand you better :-)

But the question still remains,, does this DAC accept 192 data in NOS mode via the COAX input??

Hi again...

Forgot to say that - I also use it in NOS mode (Eg, with SRC module removed and jumpers installed).

So the same as you - mostly

Hi again..

Yea - I found it now on the forum - my touch only strams 24/96. I have not installed the EDO mode. But I have so many DSD-files(from my Sony SCD-XE800) and other high-resolution files from Bowers&Wilkins, Linn, 2l etc, AND have found them more or less not always much better than Redbook. The best is 24/96 - but it depends more on the way it is recorded and how the prosess has been done. So some 16/44.1 can be nearly as good as 24/96 if the recordings is well executed!

So clearly - your 24/192 should be good for our Direct-Dac

Yes,, but our DAC (well,, mine anyway) does not play 24/192K..??

That's why I posed the question on here: I thought this DAC could play 192K files via COAX input..??

Sorry MurphyUHF10

According to the info on hifimediy-site, the directdac(Cirrus Logic CS4398) should accept 24/192 on both the SPDIF and Coax.
So we have to direct the question to the staff at hifimediy for an answer - it can be an issue for other members that use this very good dac!
I`m mostly satisfied with 24/96 - as I don`tplay that many classical music. After trying and reading a lot about this - this is my conclusion(same as div. others).
But maybe I will try it later myself.

And maybe Steinar or someone else could give a clue to MurphyUHF10?
