However this is not a WASAPI issue IMHO - it is a driver issue.
With all due respect my 30 years professional IT experience says otherwse. I did not reach this conclusion lightly. The drivers crashed - simple as that. The drivers crashed not only in J Jiver running uder Windows 7 but in Itunes running under the mac os. And that was playing back regular 44.1 16 bit - nothing fancy. In fact when it crashed in Itunes the guy whose machine it crashed on did a dump verifying it was the driver and said he would send the dump to WFS - I dont know if he got around to it. We were hopeful it would work under windows but didn't have a windows machine to check it out on. It didn't work. ...what worried me was that fact 24 bit did not work and what horrofied me was the fact 44.1 16 bit failed under both Windows 7 and the mac os.Done that - virtually no load.Correct it shouldn't - but it does on both windows and mac.
By the way, which Audio GD DAC are you listening to, Ref 1 or ?
The WFS had a slight sibilance control issue totally lacking in the 1704.
My concern is this sibilance issue. 'no doubt the Computer -> DAC interconnect issues will get resolved.For the first time ever, I've ordered a product sight unseen, more importantly sound unseen.I don't have the DAC-2 yet and now I'm very concerned about this possible sibilance. This would drive me nuts.I'm tempted to cancel my order to await more reports on how the thing actually sounds.suggestions would be greatly appreciated from anyone!

I am going to keep the order in place and have a go at W4SDAC2. I know most of us have our own specific hot-buttons in audio, mine is and always has been that overly sibilant sound. Afew months back I bought a Dac-magic to experiment with PC digital to DAC. The experiment was a raving success and I've now got the beginnings of a 24bit/96khz music library (FLAC) on NAS. As good as DACMagic was, I'm presuming the W4S will better it in most respects.One thing that just hit me, is W4SDAC2 capable of receiving firmware updates in the field?
Glad you got your dac/computer working the way you wanted it to.
Regarding sibilance I think that this can often be put down to the recording that we listen to and cd. In my experience vinyl doesn't seem to have the same issues that cd technology displays. I have finally got my amplifier repaired and I find that sibilance can be an issue but it also depends on the recording as well. Whilst quality of components does matter to a certain extent in the end the recording seems to provide a certain amount of influence on the outcome of the sound.
actually got it to work by using the Kernel Streaming mode of J River as recommended by EJ at WFS.
You need to find some 24/192 native files (no stinkin' upsampling). They are incredible sounding. My hiRez circle has several links to free ones.
It does concern me a little that you can only get the W4S DAC to work in USB mode with Kernel Streaming, though. From various USB DAC's and USB/spdif converters I've used, I know from experience that it's much easier to get kernel streaming working with USB than ASIO. It's also much easier to get ASIO4All working compared to ASIO. Unfortunately, I prefer the sonic qualities of ASIO (Otachan) over KS and ASIO4All, so I continue to look out for USB DAC that will support ASIO. And I can totally understand why KS seems to reduce sibilance because IME, KS sounds "smoother," less sibilant, and more laid back. Guys who are into vinyl usually prefer KS over ASIO, for example. Me, I like my coffee strong enough to rip out my stomach lining, and I like my music clear, present, and dangerous
I have heard good things about the AQVOX ASIO drivers but have not seen anything about how to get it working with J River and there is still the clicking issue.
I would be interested in reading the good things written about the AQVOX ASIO drivers because I tried them out and was not impressed.
I have a few as well. Must check them out.
