At this bargain price this super solid hybrid preamp becomes a super starter preamp.The BHK Signature Preamplifier features two 12AU7 dual triode vacuum tubes in the input stage that act as a zero feedback balanced input amplification pair. A combination of an input stepped attenuator, built around the highest quality passive components for coarse volume adjustments, coupled with controlling the actual gain of the vacuum tube for finer steps, turned out to be the most sonically transparent level control we have yet heard. Finally, the output stage is a high-bias class A MOSFET design that is unaffected by cable and power amplifier interface challenges.
