PS Audio’s BHK Signature 250 amplifier integrates vacuum tubes into its audio setup with impressive results.

The idea is to create an amplifier that allows users to experience the clarity of vacuum-tube sound and to offer them the ability to swap out sets of tubes to create different variations of sound.

The amplifier has 250 watts per channel at the standard 8-ohm speaker rating. The BHK Signature 250 amplifier will also be available as a monoblock called the BHK Signature 300.

The PS Audio BHK Signature 250 amplifier costs $7,500.
