Description

Measuring 9″W x 7″D x 3 1/2″H, the BorderPatrol DAC is a basic black box with a silver front plate and a small opening in the top plate revealing copper shielding, which is used for the entire case, except the front panel. BorderPatrol sells it in two performance levels: standard and special edition (SE). Each can be configured with either USB or S/PDIF, or as switchable between those two inputs. SB data are handled by a C-Media CM6631A chip feeding a TDA1543 DAC chip. No oversampling or digital filtering is used, and output is direct from the chip to the rear RCA jacks via film-and-foil output caps. A choke-input-filter power supply uses hybrid tube/solid-state rectification. The SE version also adds a twin-power-transformer arrangement and an Elna Cerafine power-supply capacitor. Gary Dews of BorderPatrol says he believes that his power supply approach, with its tube rectifier and four transformers/chokes, “is unique in a digital-to-analog converter.” Prices are $995 for the standard single-input model and $1350 for the special edition. The switchable model is $1500 for standard and $1850 for the special edition.
