A new version of Ivan's  E1DE 9038S  is due in any time , it will include an android app thats able to tweek the dac settings via usb, it also has improved performance over generation 2 ,lower noise , lower distortion and wider bandwidth , at 384khz he quotes 5-160000hz +0.1/-3db .
Just goes to show how much easier it is to design a DAC than an ADC. Now if he could make a ADC flat out to 80KHz I would be interested.

Cheers

Ian

Theres not much in the way of ADC out there really ,
There is one old TI evaluation board that looks good ,  PCM4222EVM  ,
It will do up as far as 192khz , every parameter is adjusted by jumper old style
Uses high grade op amps and keeps everything balanced right up to the ADC inputs .
Its around a long long time and doesnt support higher sample rates , theres also around 100 jumpers to set all the parameters:(
It is available from Alied for 175$

TLV320ADC6140 quad-channel 768-kHz Burr-Brown™ audio ADC evaluation module  is also an option ,  it comes with an xmos usb controler card , every parameter is controlable in a very comprehensive software called pure path console.
     http://www.ti.com/lit/ug/sbau335/sbau335.pdf 
the unit can be configured for many different uses
You get either balanced or unbalanced inputs 2v(1v) basic sensitivity, no fancy op amps up front .  200$
A 30$ USb Xmos board and one of the TI ADC chips on a break out board might do more or less the same job ,but without the additional software that allows full access to the dsp /mixer settings easily.

Im very tempted to try one of the E1DE Gen3 DAC's and use it as source for  test signals,  with the calibration available on the chip itself via the app it should be able to offer up an extremely accurate low distortion test signal to well  beyond 100khz.
