H-CAT DAC

Sorry about the trouble.  That's interesting that Roger has not responded.  I can tell you that he's still in circulation, as based on a bunch of back and forth here in another thread about his creating the best amplifier made, I paid him a visit this past November to assess his claim.

Aside from that, I'm guessing the DAC employed a universal remote.  You should be able to pick up a replacement at a big box store or online, and with some (or a lot) trial and error, find the correct codes for the DAC.  Poor consolation I admit, but you should find success in getting the car back on the road

@folkfreak thank you for providing the link.

In retrospect, I should have remembered to update this thread after hearing of Roger's passing.  I apologize...
