LosNir,
 
I don't use an isolator. I don't even know what it is.

Humm, these PC settings sound awfully complicated. It did not work for me on OS X at first, but it's because it's not completely idiot proof and I managed to forget to install the custom drivers. It's been running smoothly since. Good luck Patu. Oh, I'll consider selling you my MBP, as the new version with retina display has me envious .

 
Oh, I had it running smoothly right from the beginning. I was just wondering why I can't get the HD-material to work with WASAPI and KS. It works perfectly through ASIO output though.
 
I was also wondering how to get the 64bit ASIO driver to work in foobar2000. Shouldn't it work with 64bit Audio GD drivers? Now I use 32bit driver.

guys, do you have to manually change bit-depth and frequency in Audio-gd ASIO control panel each time you switch from a 16/44.1 to a 24/96 track?

 

[LosNir]

Where can I get HD material for free? I can check that for you. All of my collections are CD-rips at 16/44.1.

 

[kr0gg]

you can convert any file in foobar with flac-encoding plugins

No, it switches automatically.

that's strange.
there is an "auto" option in Windows XP, but it's not there in Win7

Got my DI-DSP... 2nd impressions!
 
Still stuck to sbt - spdif - DI-DSP - spdif - RE9. But it starts sounding better each day. However, sound got extremely revealing. Some recordings just sound great, others really hurt the ears and I am forced to turn down the volume, the voices or trumpets can get just so sharp. However, with good recordings the sound is just to lay back and enjoy seeing the musicians in the living room.
 
Probably the chain just got more "revealing". For some tracks however, a setup a bit more forgiving would make music more enjoyable. 
 
The difference at 16bit/44.1khz - files (upsampled by DI) is still much more obvious than with 24bit/96k - files (not upsampled before they get into the DAC). This does not surprise.
 
So, I am still looking forward to get to SBT - async USB - DI-DSP - I2S - RE9.  For the I2S, my order is placed and the Kits are on their way...
 
Just one issue I encoutered:
 
Sometimes, a little crack is audible, or the beginning of a track is muted of for a second, when the frequency changes from 44.1k to 96k or vice versa. This has probably to do with the fact, that DSP 3.1 (inside the DI) does switch the upsampling rate automatically (contrary to the DSP1, as inside my RE9, that remains on an 8x upsampling rate, regardless of the input frequency). However, the step forward in audio quality makes in worth it.
 
Cheers!

I made some more tests and it seems that the device is not working as promised.
 
I can output 16/44,1 with no problems. I thought earlier that HD material switches the output automatically to HD but it's not so. If I play for example 24/176,4 stuff, the DI-DSP outputs it as 16/44,1 kHz, if I don't manually switch the output audio format. As you said, there's no auto-option in win7. But when I change the audio format to 24 bit, 176400 Hz from the drop down menu, I can't get no audio out from the DI-DSP. With 24/96 I can get audio out but it drops the signal every few seconds and eventually the signal is full of noise and other crap. I have also got many blue screens and automatic restarts when trying to play HD-material. It usually says that the reason is USB driver bug error or something and once it gave me the "IRQL_NOT_LESS_OR_EQUAL". 
 
In short, I can't play any HD-material through this device! The old DI v1 worked fine with HD-material (96kHz and 192kHz), it just didn't support 88,2 or 176,4 material. 
 
The driver package seems to be the problem here. We need new drivers quickly!

Just goto hdtracks.com   The demo files they have are in the same file format as the files you download from the same page.

in DPC latency checker on my main PC (win7) i usually get 45-55us latency when working and having around 20 windows opened in Firefox.
..what's strange is that playing music using DI-DSP raises latency to a permanent 5000us. Yes. Five thousand.
That might actually mean some kind of ultra-high priority setting for DI's drivers and that this (5000us) is the latency for any process other then playing music, which would be a good thing.
but.. i've never seen anything like this yet.
 
 
on my other PC (which i'm currently building for a CMP music player project on Windows XP SP2)  i get latency of around 200-300 when playing music with DI-DSP.
 
 
but....i'm enjoying the new DI. a lot.

I'm not at the moment since it doesn't support HD at all. I hope this gets fixed soon. I already e-mailed Kingwa, let's see what he responds. 
 
Any other reports from users with 64bit win7 and DI-DSP? Please check if it really outputs the signal in HD-format when you play HD-music. I use Naim DAC and there's a HD indicator on the front panel when it's fed with HD-signal.

actually i found out that bit-depth and sample rate in Win7(x64) change automatically by themselves.
i'm currently playing a second 24/96 album and it shows in Audio-gd's panel - Stream Status: 24 bit, 96000 hz

Yes I get the same text in Audio GD control panel in the ASIO CPL page but the output signal is still not HD. Audio CPL page seems to show the true audio output format. Naim DAC would recognize it as HD and the HD indicator LED would be lit. Only when I manually choose the output signal from the drop down menu (for example 24/96) the HD indicator led gets lit when playing HD-material. But that's when the problems start as I described earlier.

Mine arrived today
 
It has foam feet!, The BNC/RCA connectors are much better quality and fit
 
I cannot play anything above 96 (44.1/48/96 all work fine)
 
DI-DSP win7 64bit Foobar

 

[LosNir]

I can't seem to play 24/96 or 24/192.. foobar plays and all but there is no sound. I don't need if it's my dac (Oritek V4.0) or the DI..
