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.

there is both 5bit AND 6bit delta sigma output on the pcm4222

Novice question about DSD. I have several DSD Disks, and a few DVD-Audio High Resolution Multi-Channel MLP Disks. I have even heard same Dianna Krall releases on both, DVD-Audio MLP Downmixed wins hands down. It sounds more like Analog, it has a much wider/deeper Soundstage, way more decay in the HF, and I would say sounds about 90% as good as a Record. Concidering Blue-Ray Audio is on the horizon,
is it wise to invest alot of money in a DSD Format that will soon be 2 Generations behind? Especially since many are currently using DVD Audio Extractor to Rip Multi-Channel High Resolution DVD-Audio MLP to their Hard Drives.
If Blue-Ray Audio ever takes off, DSD is going to end up a
Dinosaur Format. Should anyone be investing tons of their
hard earned money into it now?

Well, the source/quality of a lot of DSD material is heavily debated, whether up-sampled from 16/44.1 at the worst, or simply made without proper considerations. I really can't say (personally) one way or the other is superior, as I haven't tested them side by side using real high end converters with all other variables controlled, and there are MANY variables. Honestly I think fair comparison is hard to come by. I am always open to try out new gear...
Also for those who have invested in DSD materials, having the option of using high quality DAC's is a fair use right of the consumer, why buy the same record as vinyl, than tape, than cd, than sacd, than bluray, enough already, we should work to improve the formats we have, they ALL are capable of at least decent quality paired with a well built converter/analog stage

i wish audiophile DAC's could accomodate DSD, as i just saw the Korg MR2000s which will A>D in DSD...and my buddy has a gazillion records i could record with the Korg, then keep on my hard drive (as i've no room for vinyl).

shame there's no DSD input dacs out there, or is there?

I've been eval'ing the new M2tech Young DAC, which is capable of up to 32/384 via USB. I've been listening to DXD stuff from 2L's test bench download area (24/352) and it's very nice. The DAC is somehwat in its early stages and a little unstable with its firmware and drivers, but M2Tech is all over it.

I also heard the new Playback Designs MPS-3 DAC at CES (THE Show at Flamingo to be precise) and it was doing some 24/252 that was sublime. Jonathan purports that it will do 5.6Mhz via USB when released in the Spring
