can someone suggest a good design/kit
Could you make recomendations of a quality design that acheives this? Ideally one with pcb layouts, but not really necessary.
Also what modification would be appropriate to light an LED on the front panel to show the sample frequency? My current teac dac does this, and I'm planning gutting it and replacing with a better more modern design.
TIA

I only know of two relevant designs on the net. For the first I cannot remember the title of the thread but do a search under
'pquadrat and PCM1704'. The second is Dave Broadhurst's dac which you will find at

You display the frequency information using a LED by decoding the information provided by the input receiver or if there is no receiver you can use a small microcontroller. The receiver datasheets and application notes will have examples as to how to decode the frequency information.

Done a search, link here:

but can’t view the schematics
Are this schematics build able?
Can anyone direct me to a correct link?

excellent, thanks for the links Ray.
Pquadrat's build looks a real goer. I think I'll hang on and wait for the buyers of the "seven boards" to post some feedback. I'm really interested to hear some reports on how it sounds and what, if any, improvements could be made.
Hopefully Pquadrat will produce some more boards or/and post his gerber files.
All I need then is to add frequency display and RC5 controled input switching to integrate it fully into the rest of my system.

Try , http://www.viewcom.force9.co.uk/index.htm. The higher grade devices may prove to be special order items though.
Alternatively, there is the long list of sales distributors on the TI website e.g. http://www.abacus.co.uk/products.html

The only on I can find is Digikey, who quote an estimated delivery date of 26th May
I'm in UK BTW
