Most intriguing DAC?

There's always a lot of hoopla when a new DAC comes out like the ESS Sabre32 and AKM 32 bit DACs. But these are all on silicon.

Few manufacturers actually makes discrete DACs. In the past, I was only aware of one company, Meitner, (may be dCS?) that did this. Recently I came across MSB Technologies Platinum DAC III that use closely matched discrete resistors (0.1% tolerance for standard DAC, 0.01% for the Signature upgrade, and 0.001% for the Diamond upgrade). It is a variant of the older, but highly valued, ladder DAC. MSB is one of few DAC companies that offers a steady upgrade path. I really find this DAC intriguing. But why is this DAC hardly mentioned on audio discussion sites or in the press?
