New PS Audio PerfectWave

i find it odd that ps audio did not use one of the 32 bit dacs readily available. the buffalo dac may rival the ps audio dac. it's too early to tell.

I think there's a discussion at the PSA forum where PS Audio states they tried many DACs, including one of the ESS Sabre Reference ones (don't know if it's the 32 bit model), and they just liked the Wolfson better. I think Wyred 4 Sound is basing a DAC on the ESS Sabre Reference, so it may be one to watch as well.

The number of bits utilized does not necessarily mean a DAC will perform better. The nearly $70,000 dCS Scarlatti utilizes a 5-bit DAC (albeit is a proprietary "Ring DAC" - interesting technology).
