Playback Designs Merlot dac


I wanted to ask if anyone knows how this dac works? Is it a proprietary delta sigma dac based on Playback Designs' own software?

PS Audio Direct stream has a lot in common with playback  designs for their 
Master engineer gave the gifted software engineer from Microsoft
A lot of knowledge in DSD, design  ptogrammable software 
Which is how they operate native DSD, their new Huron firmware upgrade is Very Good. IMO an exceptional dac and for far lower money then most of their peers.

I see you have a Merlot for sale on Audiogon.  Are you going upscale?
