The BorderPatrol Control Unit pre-amplifier is the result of a long and protracted design process during which many circuit topologies and components were rigorously evaluated and selected on a purely musical basis. Many manufacturers simply prescribe a collection of 'audiophile' components and assume that incorporating them into their product will automatically ensure good sound. This is usually far from the case. Each component has to be evaluated, regardless of reputation, and selected only if it blends into the whole. The operating conditions of the valves need to be carefully tuned in, and each part of the circuit need to be harmonically in sympathy with each the other. The aim, like in all BorderPatrol products, is not to produce an amplifier that excels in one particular audiophile area but one which has balanced and integrated musical qualities.

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.
