A VERY interesting DAC indeed

Has anybody here heard the new Invicta Dac ? It sounds like the engineers behind this are very qualified and are part of the same team behind the highly reguarded ESS sabre dac.
LOOKS nice but what are the REWIND PAUSE and FAST FORWARD buttons for???
I think is priced around 4k...wow.
Srajan at 6 moons posted a review of it. Looks like an interesting piece of gear.
It got a very good review on headfi but I would like to hear from actual owners. I'm really interested in it but hesitant to drop 4 grand on a newcomer( and all the implications that goes along with that).
