Default Who has the "best" PCM1704 DIY board/design/kit??

Ok,

I really really do not want to lay out my own board, and build from scratch a new DAC. I would like to a) mod an existing board/kit/DIY project (not really...) or b) just jump on board with a diyAudio design/board or a "commercial" product/kit/board...

Most of the Chinese boards that I have managed to stumble across seem to be simple implementations of the baseline "eval board" schematic(s).

What I think I am looking for is: CS84XX -->DF--->PCM1704--->whatever (i'll rip that out anyhow - analog part = no brainer for moi). I'd like to find something where someone spent some time on the input /clocking/PLL, the isolation of the sections/cleaning up the edges, maybe even highspeed opto isolation (asking for too much?), and at least differential DAC chips... paralleled would be nice, but not essential.

I'm not convinced of the sonics of the newer chipsets from TI, since I don't yet know how it works...

But if anyone can suggest some projects mentioned here that embody at least some of the above, if not all, that would be superfabuloso, or outside websites with boards/kits/etc that seem appropriate too...

What I would like to avoid is what I have now, which is the CS8412 "flying" above where the original surface mounted receiver chip was, and wirewrap wires looking like a hydra going back to the board... avoid that or worse... 'cause then it starts to look better to start from scratch...

Any input would be appreciated!

Oh, if there isn't one, and you think you might like to participate in a diyAudio or outside diyAudio effort to make such a thing, a 'few-holds-barred DAC', and have something to bring to the party, please let me know... email is good.

You can take a look at my stuff if you care. I hope you do not want to sell "modded" version of somebody else's board as your own commercial product. Right?

I would never ever use another person's or company's product or designs without a written agreement.

I would put my bet on TentLabs 1704 DAC with tube output. For now Guido only sells the complete DIY CD player kit, but probably over the next few months he will offer the DAC module separately..

www.tentlabs.com/Products/diycd/index.html

haven't heard it yet, just my two cents.

Default RAKK

Is the 1704 pin compatible with the 1794? I'm quite happy with my RAKK DAC from kandkaudio.com in the USA and they'll also sell you a Tent XO-DAC.
