Default FreeDSP Killer? Cheap ADAU1452 with all data lines available

Unlike most eval boards which give access to half the data lines or have an inconvenient implementation (wrong format, too many/few channels, onboard codec) this one is a bare minimum with every data line on the pin header.

Now the bad news... Unfortunately its available only on taobao.

SIGMADSP ADAU1452???-???

I used superbuy as the in-between, total shipped was ~$27 and included inspection pictures taken with rusty potato. (attached)

In my setup it'll be combined with a few adc/dac modules, wm8804 (wondom module), csra64215 and a wondom 1701 module.

MediaWorks also makes a codec board I am interested in, but its designed for SHARC boards and costs more than I can justify with my current surplus of such components:
MW-AUDIO-EXT ?????-???

Nice little board for the DIYer as it removes the need to solder that PITA ADAU1452 package at a good price! Ideally needs a decent "motherboard" designing to get the most out of it? A decent 2/4 channel ADC and an 8 channel DAC and it would make for a nice crossover for a pair of speakers.

I like going all out playing with my own designs, but the price you can get fully assembled PCBs from the far east/China is quite amazing really.

Agreed, unfortunately their codec board I mentioned is not pin compatible and a bit pricey ~$80+shp. There is an ad1938 board meant for another 1452 dsp board that could be about half the cost but it's construction and components are suspect.
