For sale is an excellent mechanical condition Bifrost OG with OPA 1656 opamps installed in the DAC I/V and Servo sections. These are a big upgrade for the Bifrost MB as the original opamps were poorly rated. Newer main board revision on this Bifrost, despite lack of USB. The chassis itself has a few scuffs and scratches, hence the good condition rating.

Not many of these modded units come up for sale. A quick Google search will tell you all you need to know about these modded Bifrosts. If you happened to score a Piety, this DAC has incredible synergy for the best DAC/AMP stack you can get under $1k I would wager.

The price includes shipping & PP fees.
