BorderPatrol SE-i DAC (click to enlarge)

What happens when you combine a power supply design from the 1930s with a digital chip designed in the early 1990s to make a DAC in 2020? That’s the question I wanted to explore with the BorderPatrol DAC SE-i.

BorderPatrol Audio Electronics is based out of Maryland and headed up by Gary Dews, owner and designer. Gary began his audio career in Brighton, in the UK selling Audio Innovations tube amplifiers. In fact, Gary started BorderPatrol in 1993 while he was still in the UK (notice the irony since the UK does not have a border patrol). He moved to Maryland in 2005.
