The winner of a prestigious HiFi Choice Editors Choice award and featured in the HiFi Choice Collectors Edition, the BorderPatrol Control Unit is a high quality tube pre-amplifier that combines the very best tone and resolution coupled with the ability to swing real dynamics and remain graceful and composed on all music programs. The super low noise floor reveals nuance and inflection that is buried by other designs and brings the listener closer to the players.

Staying true to the BorderPatrol design ethos, an elegantly simple triode audio circuit constructed with top quality components is fed by a sophisticated over-engineered power supply unit. Housed in a heavy gauge copper chassis, the point -to-point hard wired audio circuitry is mounted on a hardwood sub-chassis and uses Duelund CAST output capacitors. A tube rectified, choke input filter PSU with Black Gate and polypropylene capacitors handles the high voltages.

The Control Unit is equally at home playing classical, rock, jazz, ethnic, technology or any other music genre and we are sure that it's musical capabilities will more than exceed your expectations.

A phono version is available featuring a 2 stage hard wired triode phono stage.

All Control Units are fully upgradeable to EXT2 specification.
