I have been running the Bricasti M1 for over two years in my top system (which for me is like an eternity to keep a DAC!), and have had it upgraded to the recent version which supports 2XDSD and includes a completely new DSP board and OCC wiring. They have just released a new LE version which retails for $10K in the standard anodized black finish which I haven't heard yet but is supposed to be another significant improvement. The company and its owner, Brian Zolner, are top notch and an absolute pleasure to deal with. They are extremely responsive and supportive of their customers, and are offering the LE upgrade to current owners for the $1,000 difference in their price. My dealer also now sells the Berkeley Reference at $16K plus the additional cost of their USB converter and says it's a step up, but other than that the M1 was his reference DAC of choice. It's a very solid performer with an excellent balance of dynamics and musicality, and has received universal praise from virtually every reviewer that has had it worldwide. The picture shown above was with the original middle power supply which was later improved, so here's a picture of later production but before some of the other more recent upgrades.
