Anyone using a USB DSD DAC?

Is anyone using a USB DSD DAC?
I only know of 3 ways for someone who might want to playback DSD files from there PC.
- Mytek Stereo192-DSD-DAC with USB
- "USB-Dual-Audio" PCB from ElectArt
- USBPAL PCB from RigiSystems

The New Mytek Stereo192-DSD-DAC is capable of playback of DSD 64fs 2.82Mhz files over USB, I believe with a ASIO 2.1 driver, possibly being the first device to support this new standard. 1/2 Rack Mount, XLR I/O, SPDIF and USB. Price is $1500USD. This is the first real device available to play DSD files from your home computer for under $10k.

The "USB-Dual Audio" is an assembled PCB from ElectrArt, a small japanese hobbyist company. It consists of a assembled and tested PCB with an FPGA programmed to record and playback PCM and DSD (64fs/2.82mhz or 128fs/5.6mhz) over USB, USB; SPDIF; and DSD bitstream and wordclock i/o connections, and a proprietary driver and software for recording and playback. Price is $384USD Shipped for an assembled and tested "USB-Dual Audio" PCB and unassembled DSD-1794a DAC PCB, recording meter PCB, and PCM4202 ADC PCB. If you dont want to solder pcb's, you can find other options for the ADC and DAC.

The USBPAL from RigiSystems, a swiss company, is also just a pcb. Yet it appears more refined, and is designed to be used in commercial DAC's, while the "USB-Dual Audio" is geared to the hobbyist. It has a driver to send DSD and PCM over usb. I don't know what software is used for playback. Price is around $400USD for a development kit, no DAC included, gotta find/make your own.

Is anyone playing DSD, either recorded with a device like the Korg or Tascam recorders, or files purchased from a 'Audiophile' recording company selling either DSD-Discs or DSD Downloads?

I sense a coming wave of DSD products possibly. Korg is apparently working on a DSD DAW and 8 channel DSD ADC and DAC. The Rigisystems PCB can be licensed and allows any developer to incorperate DSD into there device. The ElectArt board lets the hobbyiest develop there own DAC and ADC. There was an article showing a working USB-DAC prototype shown at a convention in japan from the DSD consortium.

Maybe the time of playing (and recording) DSD as easily as PCM with our computers is coming. I know software needs development, and there are certain limitation inherent in the format (simple manipulation can be difficult or mathematically problematic). Still I know some have a real desire for very high quality digital audio.
