PCM4222EVM ADC EVM boards are available for $150, pretty nice.
These show-up on eBay for less than $100. Currently there is one board.
You'll need to build +/-15V and +5v supplies yourself.

This schematic uses Wolfson's ADC, and is made for measurements and vinyl recording:
“ADC8786″ – 24bit/96kHz audio ADC - Catalog DAC & ADC - -

You are easy to please. My X-Fi Xtreme Music was better than that and I still wasn't happy and sold it away.

It does better than that THD figure in practice. The SNR though is one of the biggest weaknesses.

I'm interested in that board but I can't figure out how to interface the AES or S/PDIF outputs with my laptop's firewire or USB 2.0/3.0. This is considered one of the best ADC's out there from what I read on GearSlutz.
