I have used the beagle board for a very similar experiment.

Heh, we all want the same sort of. I already have a crosscompiled binary of Squeezeplay ready for the Raspberry Pi which I wanted to use with this USB transport.

Russ/Brian,

I'm disappointed with your priorities.

Back in 2010 you began development of the new SotA USB interface, and since then you have been optimizing the module without getting a product to market. I know you do this as a hobby... But... every time someone asked about the progress... you indicated that you would spend time on it...

During the same period you've been very kind to update the Legato, Buffalo II->III, making new modules like S/P-DIF module, sidecar etc. and supporting the crowd. Great!

I original chose your DAC solution in the hope that I would be able to play 24/192 and I still have this hope. The toslink to my mac is not very optimal and the Buffalo II DAC is only on par with my dead cheap USBDAC based on TDA1543.

Please get the USB-interface to market. You'll easily sell those USB-modules!

Raspberry-PI seems to me the near future. Paired with an external HD and the living room TV, and having USB, pretty easy to hook up a Buffalo.
I agree with finishing, or at least getting it to market, before going ahead with others. I've been near 2 years waiting for all the components to make a Buffalo dac. I don't want to build it and just "hope" to finish it in some years. A truly good USB interface is what the Buffalo dac lacks, and not a host player.

Russ

Thanks for alll the pre-release info. You have our attention!

As others are saying this sounds like a very different product from the USB interface, possibly a fabulous product, but very different.

I believe you previously indicated the USB interface would be 2-ch only (and not dsd??), anyway. Sounds like the preferred/only USB solution is the exaU2I. I got mine playing in stereo last night ( at 2am, so this morning, actually). Can't report on quality since just a test config so far...

It does 8-ch, all resolutions and DSD 2-ch (in their player) and seems well made.

Other than cost, does that card remove any need for your USB interface?
Was that part of your rational for switching gears?
Although expensive, maybe there's no need for your USB ???
Maybe if/when your USB comes it will have other benefits.
...just asking

Thanks

frank, not to go OT, but what are you using for this? Via software in jrmc? Via hardware minidsp? Other?

Thanks

Keep in mind that, exactly since it's taken them that long, it will not be easy for the TP guys to offer something that doesn't already exist in the USB-SPDIF/I2S market nowadays (and at various price points).
That effort would be better invested in this new Ethernet device, IMHO.

neb001 · 19th April 2012, 01:54 PM

I know this is probably OT, but does anyone with experience with the XMOS eval board know if the Centrance driver supports I2S input as a recording device? I'm wondering if the xmos board can be used as a digital interface for measurements.

Hi Russ/Brian,

I would encourage you all to finish up and release the USB module, if only for my own self-interest. I don't have any interest in a Squeezebox-esque device, but I do need an upgrade from the TP PCM2707 module I'm using with the COD now.

I could buy Lorien's XMOS board or the exaU2I, but the rest of my DAC is TP (except for the Magnequest output transformers) and from what I gather from this thread your module would best fit what I'm trying to accomplish.

I understand you guys are hobbyists and do what you interests you first and foremost. But, if this module is going to be shelved, whether that decision is made in the near term or in the far off future, I'd appreciate a heads up so I can move on as well.

Regards,
John

Hi Russ,

I'm sold!
AirPlay on raspberry pi

You will still need the USB module with this, am I right? How else would you connect to buffalo?

This will be awesome!
