Natural, sweet, open and organic are not words usually used to describe digital electronics but those were the design goals for the BorderPatrol DAC. Too many digital audio products sound processed, unnatural and uninvolving and this is particularly true of many of the new generation of hi-resolution DAC's. The most natural sounding DAC’s are usually NOS (no over-sampling) designs based around the ‘old technology’ R-2R resistor ladder chips with no digital filtering. When carefully implemented, designs like this can sound refreshingly natural and organic.
cheerfully confess that this DAC has been the most entertaining
thing to hit my rack in years.
If you’ll pardon the hyperbole, at $1,850 with all the bells
and whistles, this DAC blows the doors off of
(~$1,000) is from BorderPatrol,
whose “entry-level” DAC certainly doesn’t sound entry-level.
Being a BorderPatrol design, the power supply naturally
received a lot of attention. Improvements to the power supply
dramatically improved the sound of the DAC proving once
again that everything comes from the power supply and its
not what you use but how you use it that counts.
The DAC is housed in a copper case chosen for it's rich, lustrous sound quality.
Available as USB only, SPDIF only or switchable USB and SPDIF. The USB version of the DAC also features a SPDIF output which enables it to function as a very high quality USB to SPDIF converter.

R2R DAC chip which has no over-sampling (NOS), no digital filtering and no output buffering.
quality signal capacitors couple
Tube/solid state hybrid choke input filter power supply featuring over-sized power transformers, high speed low noise diodes with resistor-capacitor snubbing, a high inductance choke and a EZ80 tube rectifier. It feeds both the USB/SPDIF and DAC cards which each have independent voltage regulation.
The SE version features a novel BorderPatrol twin transformer power supply system (as used in the BorderPatrol EXS amplifier PSU's), ELNA Cerafine power supply capacitor and film and foil signal coupling capacitors.
