Thanks! I see the thread now and will read through it. I'm hoping it will allow a for a B3 multichannel solution.

Brian and I are actually still considering producing the USB module, but I will likely simplify it quite a lot.

I actually have it laid out - Brian and I have been discussing some changes to it which will make it more usable with current and future DAC modules.

Sorry to be cheeky but is there any chance of making some kits available for the old USB receiver or even bare boards?

Default Sonore USB interface

Hey guys, I have asked permission to post this here, and Russ has graciously granted it.

For those looking for a very high performance USB interface for their Buffalo DACs, you might want to consider the Sonore USB interface. Jesus and I developed this after we became frustrated that we could not find a really good interface with the features we wanted for our Buffalos. You can see the details here:

Sonore DIY USB Interface - USB to i2s interface

I am not sure if the TPA forum is the right place to discuss this, so if you have questions or comments, please make them over at the audio circle thread. I know, it is expensive, but, if you do the math on the chips and oscillators onboard I think you will understand.

Edit: Oh yeah, for those who would rather stay at the diyaudio forums there is this post in the vendors' bazaar:

Hi Russ,

I have to say that at the moment I'm working on a very similar project - XMOS based AD-DA converter.
If you wouldn't mind, may I ask you a few questions?
1. In terms of ESS adc chip. I wish to use their ES9112, but I don't seem to be able to get documentation for it. I have filled and send the NDA, to Ismosys but they seem to ignore me after I said that I'm only interested to build a prototype and that I don't really work for a big company and etc.. I wonder how did you manage to work with them or they were not so strict at the time?
2. In terms of I2s configuration, how did you do it on software? Did you do it all by yourself or you used some libraries? I only want to use PCM over USB and I'm pretty much a beginner in programming. I have found some valuable libraries in xSOFTip, but I wonder how to integrate them properly. I would really appreciate if you could tell how did you do it in a bit of detail. Or maybe there is a proper tutorial about how to do it somewhere?
ps. What I'm really doing is not a commercial thing. It is just a project for my university and I'm not likely even to publish it anywhere, so I'm not going to steal your ideas or anything. If you could PM me with answers, that would be highly appreciated

Thank You,
