With 9 posts all of which are about Musicland I would say it's a pretty good guess.
jtam, while you are still there, can you please elaborate on async implementation.

I decided to sell the Bel Canto USBLink and keep this as I think it performs better technically. Only drawback is the drivers, however Windows 7 is better than vista so unix is still there but... 24/96 is ok. I might keep it for a little while longer but not much.

Could you do more in-depth preview between these two?

Is this with the updated drivers from last month for Vista?

Thanks

To my best knowledge, the USD has a pretty precise internal clock and a data buffer. When receiving data from the computer via USB, the MU1010/6010 chip sets feedback the master clock back to PC to control the speed of the data stream. They claimed that the algorithm they used is good at controlling jitters.

alright Patu Ill compare them side by side tonight and post tomorrow. More detailed breakdown of what I hear.

For 16/48, you can say most bits are perfect whatever driver you use.

For 24/192:
Using foobar with DS, it's not bit-perfect, even if you maximize all volumes.
Using KS, it is bit-perfect.
using ASIO, the first piece of data is not perfect. The following data is bit-perfect. Some devices may not lock on 24/192.

So, KS is recommended for this sound card.
Do you know if Vista's WASAPI exclusive mode will work with this card? I believe WASAPI is Vista's native implementation of KS.

Do it
My M-Audio Transit sucks with Vista. I'm looking for other options, this one and the PopPulse are great choices now.

I have not seen any reports (yet) about this running on linux.

any plans? can you (ebay guy) ask the manuf if they plan to have linux support for this?

Asked, no hope for Linux.

They plan to make a very similar model for Mac though. Good news?

I imagine it should work, KS and WASAPI are pretty similar. KS does work under Vista, although poorly, but it is considered the better choice for USB devices according to Foobar2000's wiki. That said, I'm using WASAPI with my USB X-Fi sound card and it works great. Just had to set the output buffer as low as it goes in Foobar. Don't know if you use F2k or not though so that might not have been very helpful. Here's some general info: ASIO is more selective about the devices it works with; there generally need to be specific ASIO drivers for a device in order to get it working (with the possible exception of ASIO4ALL). WASAPI will work with any audio device with a Vista driver. The end result of either method is pretty well the same. Not sure about bit-perfect output via WASAPI, though I know it can be done in ASIO. I don't care much about it myself, I just like to block out all the other sounds on my computer by using WASAPI. There's a link to a guide to setting up WASAPI and/or ASIO with F2k in my signature if you're interested (as well as instructions for ripping CDs to FLAC using EAC).

not for me; mac is not linux.

I have a fanless pc that runs linux and mpd (music play daemon). my config works well with standard usb audio devices (from a very old xitel usb/opto box from 2000 timeframe up thru the BB pcm chips and cmedia chips).

but I'm NOT willing to dump my:
- os
- apps
- config

because the company is too 'proud' to tell us how their code or architecture works. they won't play ball with the open source guys, I want no part of their products.

sorry.

go tell them they lose a LOT of sales because, more and more, media players are going linux as the back-end.

and this hiding game that vendors play; reminds me of those that rub off the chip names before they ship the board. I can't support companies that do stuff like that.

thanks for letting us know. it would have been a shame to order one, TRY to get unix working with it only to find out the vendor doesn't ever want it to work with unix.

I agree with Linuxworks - it really needs to support Linux for true audiophile use which is what it is purported to address.

Here's an announcement from Musiland (translated) which talks about the Functional units & their workings, Includes USB 2.0 support, using Xilnx FPGA gives 24bit/768KHz, clock management unit for low jitter clock 1PPM(?) plus it mentions future functions (through software) of multichannel support, DTS, audio effects,etc

Sorry for the long quote but I thought all of it interesting

A new generation of high-definition MUSILAND upcoming chipset USB AUDIO

MUSILAND Audio Labs is about to release a new generation of high-definition USB AUDIO solution, independent from MUSILAND Audio Labs research and development, there will continue to be issued a number of models. Traditional sound card with the previous chip is different, MUSILAND Audio Labs solutions developed by the two chips ICU (I / O control unit, I / O control unit) and APU (Audio processor unit, audio processing unit) Unit into a similar computer motherboard chipsets Dragon framework, ICU and the APU through high-speed parallel bus communications.
First of all, the listing will be Monitor01 HD-USB chip set by the ICU (I / O control unit, I / O control unit) MU1010, APU (Audio processor unit, audio processing unit) MU6010 composition.
ICU MU1010
ICU MU1010 the use of generic CPYRESS programmable processor (DSP) to achieve. MU1010 true USB2.0 support high-speed transmission, the instantaneous transfer rate up to 480Mbps. With sarin MUSILAND driven by high-speed parallel bus, bi-directional transmission of up to 16-channel audio data to the APU for processing. Cache and multi-layer state machine to deal with the mechanism to achieve MU1010 makes the system similar to PCI device priority levels, USB high-speed transmission of data so that the true real-time.
APU MU6010
APU MU6010 common use of XILINX field programmable gate array (FPGA) to achieve. MU6010 Audio 24Bit support for real data processing, sample-rate support to 768kHz. In addition to between the ICU and high-speed parallel data bus through the exchange of audio data, MU6010 have powerful audio processing capabilities. Moreover, the audio processor is a real-time operating system, programming can be downloaded through an independent unit. By running the different processing algorithms, MU6010 to be completed such as: Kara OK Reverberation, Virtual 3D computing, the voice of harmonic analysis, the acoustic excitation, 3D audio acceleration, multi-channel coding and decoding, digital signal to the jitter, sampling rate conversion all audio processing functions.
MU6010 with 5 groups I2S output interface connected to 5-chip stereo digital-to-analog converter (DAC), to achieve up to 10 channels of analog output. 2 groups with I2S input, can connect two stereo analog-to-digital converter chip (ADC), the completion of 4-channel analog input. MU6010 also has a group of S / PDIF output interface, you can output S / PDIF digital signal. All digital I / O all have the 24Bit processing capacity to support up to 768kHz sampling rate of audio signal transmission.
MU6010 integrated precision internal clock generation circuit, to load the professional clock synthesis algorithm, the XILINX FPGA with internal DCM (clock management module) generated by the audio clock, the measured precision of up to plus or minus 1ppm, the resulting clock to restore the audio or voice recording, harmonic distortion close to the limit of human hearing.
MU6010 integrated precision internal S / PDIF transmitter. Can be PCM, Dolby, DTS and other popular digital signal output, and the future meeting times with the upgrade of audio formats. Since the S / PDIF transmitter driven by a precision clock, so the output signal jitter is very low audio laboratory to achieve the required test equipment accuracy. S / PDIF output format support physical consumer, professional-type optical fiber, coaxial signal norms, and to support the professional norms of AES transmission.
MU6010 have I 2C Interface, can be driven through the system to control external ADC / DAC. 16Bit external expansion bus, in addition to SDRAM can be used to store a large amount of real-time algorithm, or link up with other APU to achieve functions such as the expansion of HDMI interface.
At present, Sarin has mature driver (supports the latest operating system Windows 7), can be used with chipset MU1010 + MU6010. And more of the audio processing algorithm library, will be gradually enriched MUSILAND Audio Labs.
MUSILAND Audio Labs announced that it would release by the end of March this chipset, and the first chipsets to use this product, it will be MUSILAND brand Monitor01 US / USD products. The future, MU1010 + MU6010 chipset will be available to over MUSILAND and DIYEDEN In addition to third-party use of brands. High-quality USB AUDIO era.

Further research has unearthed a review (in Chinese & in 3 parts) & pics of the Monitor 01 US (same as USD but with PCM1973 DAC). Pics of board (in Part 2 ) show, what to me looks like a reasonably well designed & implemented board but it also mentions that I2S is used to send audio to the DAC. So I2S should be recoverable from the unit (I know I2S signal has to be short to avoid clock corruption). The PCM1793 is the weak part of this unit, I feel
