What I want in a DAC

My preference is that you come out with a great DAC, not a cheap DAC.  Do not need USB, though it is a nice option.  Currently using a Wavelength Brick with Mortar power supply (retail $2K) and recently bought and then sold (preferred the Brick) Ayre QB-9 (retail $3K).  I have no problem paying over a grand for something top drawer.  Just my 2 cents.
 
You guys and I are on the same track. I will try to keep the basic version around $1000 if possible (really can't say for sure yet), and there will be upgrade options like USB input, multiple power supplies and a couple choices of sample rate display. And it will do 24/192. The project got slowed down a bit again with RMAF, but we are working on ramping it back up ASAP.
 
You would provide an SPDIF output in the form of a USB to SPDIF converter of some kind like an M2tech Hiface, or via a sound card with an SPDIF output.
 
The plan is to offer the kit with an SPDIF coax input. There will be a spot on the DAC board for an optional USB input daughterboard. Perhaps the builder could repurpose that as another SPDIF input instead, I'm not sure.
 
We are discussing having a card edge slot that will allow one to have an assortment of display options. It might be possible to do a Nixie display.
 
Nixie tubes seem like a cool idea. I'd also like to retain use of a USB connection. USB is improving and I think may be "the " platform for a host of improvements. Great to being hearing some details about the BH-DAC.
Just a thought, lets have a contest to name the new DAC.................??????????????
 
John, as soon as we go for USB there will come a new and better way of connecting to a DAC.  Digital changes way too quickly for me.  I, too, think that USB will be the best thing for the DAC.  I am supposing I will end up with some sort of music server and a computer for my stereo. 

That just sounds wrong, a computer for my stereo.  Well, I can change.
 
My question about a USB input is will it be a USB 1.0 or USB 2.0 option.  I really doubt that Doc wants to get into the business of writing device drivers but without one I believe a USB 1.0 connection will be limited to 16 bits / 48 kHz.  That's fine for CD quality music, but it won't support high resolution data.

For me a second SPDIF input would be preferable to a USB 1.0 input.  If your only option is a USB output there are several good USB to SPDIF converters on the market now.  Just be sure that the one you choose supports the data resolution(s) that you require.

Might as well go for USB 3.0 now.  That seems to be the latest.

My preference, though, would be fiber-optic.  I use a TOSLINK from my Squeezebox Touch to my DACMagic.  I like the DAC in the DACmagic better but the sueezebox touch is just plain awesome as a way to serve music off of your PC.  You can even control everything from an iPhone app.
 
You guys know TOSLINK can't do 192K, yes? I'm not agin' it, it's what I'm using at the moment. But it will hold you back if you want to buy some 192K files.
