Thank you. These are easily available in the US and around the globe. But I'm a bit confused about the attachment. Is there any chance you can post a picture? That would be really helpful.

Not at the moment, but you basically clip the thing on top of the two transistors and the "feet" will face away from the capacitor. The schematic below the description shows the heatsink in vertical position and the part with the hole is the clip.
I probably should have used some of those: http://uk.rs-online.com/web/p/thermal-gap-pads/7073355/?origin=PSF_438341|acc to make better contact between the transistor and the heatsink, maybe next time I open it up.

I'm using JRiver during its trial period. I just seem incapable of making Foobar work, even with Google Translate. Oh, if I could only read Chinese :) If anyone has been successful with Foobar and can explain in English, it would probably help a lot of folks. I got it so it could play, but everything at 44K. JRiver has at least let me check the hardware.

But while, with JRiver, the LKS is recognizing and playing hires PCM files very well, I cannot make it do well with DSD. As before I'm using files from a high res sampler site, 2l.no.

Going to Tools-Options-Audio and setting DSP Output Format to: "None" I get nice sound and the LKS reads: "PCM 176K" suggesting conversion of the DSD files to PCM.

BUT setting the DSP Output Format to: "DSD in DOP format (Requires DSD Capable DAC)" or setting to "1xDSD in Native Format (Requires ASIO & 1xDSD Capable DAC)" gets me a very stuttering audio output with the LKS reading: "DSD 64X IIR 47K"

I have read of others having difficulty making DSD files work correctly. Does anyone know what is going on here? The Amanero board? The Amanero driver does show up in Device Manager, though I don't see any reference to it in JRiver.

Thanks.

subbed to this thread ''tt' dac with Roon.
i'm seeking to upgrade my current DAC |(iFi micro idsd) and setup with roon/tidal.

this DAC does look interesting, too.

You need to hit the DPLL button until it stops skipping. If you go up to 15 and it still skips then there is something else going on, I have to go about up to 8 to play DSD256 without issues.

Thank you. I tried this using DSD 128 files before, and now again and with every possible DSD setting and it didn't stop stuttering. But then, recalling that the LKS screen was reading "DSD 64X IIR 47K" I loaded in some DSD 64 files and they played perfectly in native format at DPLL 1, and at either of the two JRiver settings for DSD..

So it wasn't recognizing the files as DSD 128, hence the hiccups all the way to DPLL 15. I'm still hoping it's a setting that I haven't found yet, to wit, that it's me and not the LKS..

Are you sure you installed the ASIO driver (http://www.mu-sound.com/files/USB_drivers.zip) correctly (http://www.mu-sound.com/files/LKS_Audio DAC_USB_DSD_driver_setup_note.pdf) The trick is to stop the automated driver install and run the msi installer instead. You should see a Amanero Technologies USB Driver 1.0.57 device in device manager.
If so, then make sure your computer is not running out of CPU when playing those DSD256 files. I haven't used JRiver and I can't help you with it's settings but if it's doing any kind of audio manipulation then at DSD256 your computer could simply not be up to the task.
Also, make sure you're not in power save mode or low on battery which could affect the USB speed.
For DSD 256 you'll need to use DSD native and not DOP, also make sure you enable DSD bitstreaming using this: https://wiki.jriver.com/index.php/DSD

Just to clarify its use with JRiver (With the friendly help of Jinbo* at mu-sound):

Audio Device is set at "Combo384 ASIO 1.03 (ASIO)",
DSP & Output Format should be left at "None". [That corrects one mistake I was making.]
Bitstreaming should be set to "Yes (DSD)".

Jinbo suggests that DPLL should be set at BW08 or above. I found that necessary with some downloaded files. But My first ripped SACD* plays easily at BW04, and probably lower.

In any event, the sound comes through as DSD, fine and clear.

This is the DA004 with upgraded USB board.

*They take a few days to respond by email. Seem a bit terse, but friendly. Good English skills. I am pleased with the little support I needed.
**On an Oppo 105, it's so easy.

If I understand correctly SACDs are DSD64 which should play on lower DPLL setting. Or did you somehow up convert to DSD256?

No I leave the SACD .dsf file at DSD64. At DPLL 1 I thought I heard some very minor skipping, no static, no spaces, so I pushed it up a couple of notches. On subsequent SACDs, it seems I had to go a little higher. Haven't really figured it out yet as I'm doing a lot of copying.

Very nice looking Dac :)

Has anyone compared the lks to a Mytek Brooklyn, w4s, Hugo tt or any benchmarks?

I currently have a Matrix Quattro(with a few basic mods) I'm thinking of upgrading with something upto $2000 to drive active monitors, so I need the pre amp/volume function.

Thanks

Just a minor question for those with the DAC. I'm using the USB A to USB B cable that came packaged with the DAC. All information packaged with it is completely in Chinese, which I cannot read. Any hint of its quality, or how it is made? Are you using it? Comparisons to other cable you are using? Thanks.
