Dsd Native Problem

Tim
Would you know why pcm and dsd fed from computer via USB irdac 2 has lower volume?
Even pcm through USB seems degraded, and its at least 3 or more db lower?

Hi Terry,

What type of computer are u using and what player software?

There can be multiple volume controls in computer configs for example the Player volume control and the System volume control.

Iam using either of 2 computers
Both i7 5960s
64 g mem both fresh installs.
Vid cards. Titan black and FirePro w8100.
All chipsets drivers ect up to date.

Software have jriver and foobar.
Jriver configured to irdac 2 native dsd.

Strange thing is when I play a genuine sacd hmm examplevblues in orbit,
Which I know is a good recording. It sounds really good excellent.

I have 830 sacd rips, around 30% are good masters. Now they play perfectly on irdac,
Nearly the same as if I play them on cxn.
Cxn on most seem to be more digital, sparkly. If that the right word.
The irdac seems more analog.

Does that make sense?

You will have to excuse my way of trying to explain.
Iam new to hifi.

Just found something interesting.

Now when I play back through the irdac
Setting in jriver is.
Dsd bitstreaming.
Dsd native 64.
This is what I have been using.

Now I have just gone into settings
This time I have turned off bitstream dsd
Then turned off dsd native chip.
Then told it to sample at 352.8

It changes dramatically , it's exactly the same quality as the cxn.

Audio path info tells me
Input 352.8khz 64bit 2ch from source format sacd
Output 352.8. 32bit using asio.

So now the irdac is playing the same pcm format actually it's 352 the cxn is 192 tops
