Wyred4Sound Dac-2 vs Preamp and separate DAC


I’m about to upgrade to either the Wyred4Sound DAC-2 to use as a Preamp/Dac or possibly considering a used Classe Audio CP-60 and Wyred4sound DAC-1. If I’m only going to use a CD transport and USB to play lossless files is there any advantage to having the separate Preamp/DAC setup. I would personally think the Dac-2 would be the cleaner path but I’m a little worried about the digital volume control. Any opinions welcome. Preamp also doesn’t have to be Classe but some type of balanced pre along those lines.

I am using MPD on the server and GMPC (ubuntu desktop) and MPDroid (Motorola Xoom) to control my music. Can you control the volume within Jriver? How can you tell that it bypasses the mixer?

This is from Jriver's site about Kernel Streaming: Kernel Streaming is a hardware direct way to speak directly to a WDM audio driver. Jriver Media Center 15.0.6 (and later) adds support for Kernel Streaming output. Kernel Streaming is a hardware direct, bit-perfect method of communicating with an audio device. It bypasses any Windows mixing. It holds the card exclusively so other programs can not play music over the top or change the sample rate.

Also, you can't control the volume (at least within Windows), it's a fixed level output direct to your W4S DAC2 that goes over async USB. Within the configuration of JRiver, you can select the output device and type and the DAC2 is a "device" that you can select. It's pretty cool. I've used a lot of other playback programs, but this one sounds the best on Windows at least (works fine on Windows 7 32 and even 64 bit without any issues). It's also how you'll be able to play back high rez audio like 24 bit 192Khz Flac.

For playback, I use an Ipad with Plugplayer to control Jriver as a media render and "server" even though it's really playing the flac files locally. I'd say Plugplayer still has a few bugs to work out, but it's definitely very usable.

It would be really nice if Sonos would just get the hint and come up with an audiophile version of a Zoneplayer 90 or something like that.
Thanks! I have little experience with Windows for media services and I am happy to see that this is actually a possibility in Windows. I hope future products / updates from W4S will support USB 2.0 audio out of the box without the proprietary drives.
I just hooked up my W4S DAC-2 outputs direct to my amps via balanced outputs/inputs and installed my Parasound C2 controller using the HT bypass via RCA connections. The W4S DAC-2 works well as a digital preamp and provides clear and crisp sound. The W4S remote is not all that great to use, but a larger universal remote might work better.

Previously, I had the multi-channel C2 processor doubling as stereo preamp and processor and hooked up the DAC-2 (DAC duties only) with the balanced inputs; with the C2 connecting to the amps via balanced cables.

Both ways sound very good, so I'm not sure if I'll return the Controller to preamp duties, or leave the DAC-2 to handling the digital preamp responsibilites. So far, I'd call this install a toss up.
I thought I'd follow-up on this thread as I purchased a McIntosh C48 preamp (that also has a supposedly decent DAC) and have run my Wyred4Sound DAC2 through it. I can say from a preamp perspective, if you listen to music at low volume you are better suited to not use the DAC2 as a preamp. [take the following as you may, as this is only my opinion] The DAC2 sounds "distorted" and muddy at very low volume when using it as a preamp. When you get it above 40 all that goes away. When I connected it to my C48 and set the output at fixed rather than variable, everything cleaned up nicely. So far, I can't attest to the DAC in the C48, but the preamp is nice sounding with the Wyred4Sound DAC2. (I've got other gripes about the C48, but that's not the topic of this thread).

Anyone experience similar issues with the DAC2 preamp at low volume?
