Looking for DAC and ADC Board

Hi all, I would like to build a 16 channel DSP based on the ADAU1467 DSP and need DAC's and ADC's for it. They should be I2S capable and, if possible, without RCA sockets. The ones I have found so far have a suboptimal RCA arrangement... They should also be 24bit and 192kHz capable. I can't find anything suitable anywhere. Can anyone help me?
