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

'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”.
clearly better it, I have to go to extraordinary lengths (and budgets) — and that’s crazy.

'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.

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.
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.

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.

Available with asynchronous USB input, SPDIF input or switchable USB and SPDIF.

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

R2R DAC chip which has no over-sampling (NOS), no digital filtering and no output buffering.

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

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

Copper metal chassis.

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.

Dimensions: W x D x H: 9 x 7x 3in (226 x 173 x 78mm)
Weight: 6.6lb/3kg
Prices: S SE
USB or SPDIF only $995 $1350
