BorderPatrol Digital to Analogue Converter

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 R-2R resistor ladder chips with no digital filtering. When carefully implemented, designs like this can sound refreshingly natural and organic.

"In many respects, the DAC SE is a digital cousin to my Denon DL-103R and Ortofon SPU phono cartridges. I’m a proud owner of both, and now of the DAC SE. I encourage you to seek out an audition because you may become an owner of this bargain-priced DAC too."
Mark Blackmore, The Audio Beat

'I cheerfully confess that this DAC has been the most entertaining thing to hit my rack in years. The performance easily earns the BorderPatrol DAC SE an Editor’s Choice award, but also puts it firmly into Best of the Year territory. An absolute must-listen.'

If you’ll pardon the hyperbole, at $1,850 with all the bells and whistles, this DAC blows the doors off of just about everything else. And no, not just in its weight class. I mean “just about everything else”. To clearly better it, I have to go to extraordinary lengths (and budgets) — and that’s crazy.
Scot Hull, Part Time Audiophile

'Right away I knew the BorderPatrol wasn't just another digital converter; there was more life, more body and soul to the sound of files.'

'Once I stopped comparing and just listened, I fell in love with the sound. BorderPatrol has a musicality that you just don't get from everyday digital gear.'
Steve Guttenberg C-Net

My budget-favorite (~$1,000) is from BorderPatrol, whose “entry-level” DAC certainly doesn’t sound entry-level. It has to be one of the most wild and open-sounding I’ve ever come across— and by “open sounding”, I mean, “makes most other DACs sound broken”. It’s a little breathtaking, really, but never in that fatiguing kind of way.

How can a DAC with no oversampling and limited hi-res capability sound so good?
The answer may be found in two areas.
Early CD players sounded unnatural and uninvolving and the same can be said about most of the current generation of hi-res players. It may be that hi-res will eventually reach the musicality of a well executed Redbook design but they are not there yet.
The second area is the power supply. Being a BorderPatrol design, the power supply received a lot of attention and early experiments proved just how important it is. Improvements to the power supply dramatically improved the sound of the DAC proving that its not what you use but how you use it that counts. After much testing and evaluation, a hybrid tube/solid state design using choke input filtering was found to be the most musical, dynamic and organic. BorderPatrol is the only company that applies tube rectification and choke input filtering to digital circuits.
Also unusual for a product of this price, the DAC is housed in copper casework chosen for it's rich, lustrous sound quality.

Available as USB only, SPDIF(COAX or COAXIAL) only or switchable USB + SPDIF(COAXIAL). 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.

An SPDIF or COAXIAL digital output is found on all CD transports and almost all CD players.
COAXIAL SPDIF outputs are also found on some music servers and streamers.

BorderPatrol Audio Electronics c/o Kaja Music Systems Waldorf  Maryland  USA

Available with asynchronous USB input, SPDIF(COAX) input or switchable USB + SPDIF(COAX).

No over-sampling (NOS), no digital filtering R2R DAC chip with no output buffering.

High quality signal capacitors couple the chip to the output of the DAC. Copper metal chassis.

The USB version of the DAC features a SPDIF(COAX)
output which enables it to function as a
high quality USB to SPDIF(COAX) converter.

Plays files up to 24/96kHz via USB or SPDIF(COAX)
including TIDAL Master recordings.

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.

To our knowledge, BorderPatrol is the only
company applying tube rectification and
choke input filtering to digital circuits.

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.
