79.73.48.150
I bought the usb for a computer with no space for a sound card and it works well up with wav files up 192k with:
Foobar asio dll; no dsp; 24 bit padded to 32; output buffer set to 63; direct monitor; time critical; thread priority on Playback Low to Mid. High seems to cause hf sharpness.
Upsampling src to 88.2k (tried so far). Will not work on low playback buffer of say 8.
Only issue is occasional 2-5s interrutption (near silent) where there seems to be buffering going on.
Software update is useless (no info).
Would not install the 800 Mb of 'tools' they provided; just 100 Mb of driver with really simple panel control. Hope spdif out works - they say it doesn't except with some software.
Any one found a way of overcoming the interruptions? Gordon?
The usb dac sounds rather good.
I've been running one for about a month now, I have not had any problems at all. I'm running it on an old slow laptop, as long as I sty at low sample rates it works great even on the slow machine. 24/96 is a different ballgame.
I just loaded the driver stuff and am using ASIO drivers. I primarily bought this to do recording, it works quite well for that, way better than the FW-410 it replaced.

After 2 days, I have lost the Control Panel and only gate an indication of sample rate and lock on the toobar. Uninstall and re-intall doesn't get it back!!!
It is worth using the web install package as there is a hardware update (5.x) and this has taken the slight hf edge at high rez (192k).
Do you still have the 0404 Control Panel?
Nope, mine went away too, that is strange, I just thought it was mine. It still works fine without it. Maybe its because I'm using ASIO?

Fred,
The first thing I did was make a new power supply for the damn thing. When I had my USB analyzer on it there seemed to be errors when I tried higher rates. So I made a little linear unit and most of them went away. I think from recolection that I used LT1086-5 with a hexfred and some black gates.
I did not install all the BS as I found that usually causes problems down the line. Instead I only installed their ASIO, driver and their setup program. I have had some glitches with the setup program in the past. Sometimes it just goes off and resets itself to something else.
I did not check out the spdif, I think it's only good to 24/96 from something I read somewhere.
Inside it's pretty basic unit but it does have dual Crystek low jitter osc for 44.1/88.2/176.4 and 48/96/192. The unit does do bulk mode and so should preform pretty well. Though does have that damn driver issue which maybe better maybe not.
Good luck...
Thanks

Where is the emu asio driver? I just installed the driver software which gives me the basic control panel which selects sample rates and used the Foobar ASIO output.
Is it necessary to install the PatchMix thing which I have avoided.
Can't do it now but will drive the 0404 from a Jung regulator later.
To save me some trouble, which sets of the 4 screws do you undo to get into the box? The recessed ones or the ones with nearly flush screws?
Fred,
Got me I installed the driver only and the ASIO showed up in my selection window. I have 3 ASIO's on that Machine and it showed the EMU, ASIO4ALL and ASIO2KS.
As for tearing it apart... I can't remember I think the ones indicated by the arrows.
As for the regulator since there is a cord a simple LT is fine. Unless you want to bypass the connector and hardwire the thing then a Sulzer/Jung maybe worth it, but proabably an overkill.... unless you want to rework the opamps and other crap in there.
Thanks

I tested the spdif ouput using Foobar. Up to 96k, there is a signal but only clock is outputted at 192k. The spdif/aes output switch on the Control Panel does not work in that only 1V peak to peak is available, not the aes level which should be a lot higher.
If anyone knows how to fix this, please post.
