There's a new wave of USB to I2S converters based on the XMOS XU208/XU216 coming out. Here are some links:
F-1 XMOS USB Digital Interface Module XU208 U8 upgraded version | eBay
XMOS 768kHz DXD DSD512(DSD1024) high-quality USB to I2S/DSD PCB - DIYINHK
Thought that might be of interest to people here 🙂

They're pretty new so apart from the head-fi thread, I haven't seen anything.
XMOS XU208 USB BRIDGES - THE LATEST GEN HAS ARRIVED!
Do ignore my own stupid questions in there 😀
I've had DIYINHK's board for a few months now.
I can say that it definitely works, but I can not offer any subjective SQ impressions.
I haven't used it on the Soekris. I doubt it will sound any different than the older XMOS boards.
The OLED sure is cool though. 😛

you bought it for the oled didnt you ! 🙂
does it require usb 5v signal detect?
is it an external 3.3v it requires?
is there an onboard power regulator ?
cheers
As a matter of fact I bought it for my ADC, which does not make use of the OLED display, but I will use it elsewhere.. I have plenty of projects on track that need displays.. 🙂
I'm not sure about the USB 5V signal detect, but it does require 3.3V at over 500mA to function. I had trouble getting it to work in my setup because of a whimpy 3.3V supply. Once I hooked it up to a Ref-D configured for ~600mA current everything worked like a charm.
It has at least one on-board linear LDO, giving out 1.2V for the XMOS' core.
Back in January I wrote a post on my blog detailing my experience.
Sorry for the off topic..
seen your blog since
thats good about the 1.2v core has to be better without the internal dc-dc converter
to my surprise there was benefit of replacing the switcher for the 1.2v core on the fpga on the dam with an ldo
ordered the diyinhk bridge out of curiosity
The DIYinhk version is not isolated, however. I believe RB2013 on Head-fi.org prefers the isolated one. I am using an isolated version of DIYinhk 384khz converter but did not have a chance to compare it to a non isolated version.

Since the DAM already does isolation, an extra isolator on the USB board will almost certainly do harm rather than good.
I agree with you. Just looking beyond this, when the OEM dam version (which is not isolated) will be available it might be useful.
Having not played with the new converter the only option I have (at the moment) is to read (scarce yet) ratings of others. I guess RB2013 gave 150 to the new 768kHz converter (in his system, what may be subjective and not applicable to I2S).

That's RB2013 ratings for different converters in his system, I believe he is using SPDIF, so not necessarily valid for I2S.
This is right. However, being without a doubt subjective, his valuation has at least some indicative value of SQ. Will I upgrade now, not yet.
Besides that it is off topic. What is the problem about the list? It is just a top list from a guy who subjectively valued different devices in his audio system configuration. It is just his own subjectively ranking, it is nowhere said that this is a general list that is valid for all devices and system configurations.
