So EVGA announced their Nu Audio product at CES, and it looks interesting. It uses the AK4493, they went over board with the "Audiophile grade" components, 1/4 headphone jack, swapable op-amps, RCA and SPDIF (5.1 support) outputs, but they leave out things like output impedance or meaningful output numbers. But it certainly looks better than any PCIe sound card we've seen.
This is the parts list:
DAC - AKM AK4493
ADC - AKM AK5572
OP-AMP (Headphone) - ADI OP275
OP-AMP (Line Out) - ADI AD8056
Capacitors - WIMA, Audio Note(UK), Nichicon
Power Regulators - Texas Instruments TPS7A47/TPS7A33 ultralow-noise power solution
