New DAC: TEAC UD-501 anyone listen yet?

TEAC's new UD-501 is the star of their 501 series. The TEAC UD-501 supports DSD 2.8/5.6MHZ file native playback by ASIO 2.1 or DoP methods or up to 32bit/384kHz PCM. TEAC also packed this incredible unit with two 32-bit BurrBrown DACs per channel and JRC MUSES op amps, dual monaural design, fully balanced XLR as well as unbalanced RCA outputs.

Is BB still a leader in DAC opamps. I know they have had a great reputation in the past?
