MHDT Pagoda, anybody has listened to it?

I have been reading lately some great reviews about MDHT in general and specifically about their latest and greatest the pagoda DAC.
Its main features are an r2r design using theĀ  PCM1704 chip and a tube buffer stage (usually used in much more expensive designs).
This DAC is sold direct from MHDT at ~1,200$.

Any Ideas, thank you.
