The PS BHK Signature stereo amp is a high current 250 watts per channel hybrid amplifier designed to be the best under $15k amp available. The first review is out and it is a rave.
"I loved so much, I ended up buying the review sample… the PS Audio BHK Signature 250 Stereo Power Amplifier."
"So what does all this mean sonically or musically? Well, simply put the BHK 250 rocks and does so with a nimble presence that puts the music in the room with you. Neither forward nor recessed, the presentation is, for me, spot on. Fast and coherent, extended and dynamic"
"I can't recommend the BHK 250 enough. Like I said I bought this one and it is now here between the speakers"

The BHK stereo amp is a 250 watts per channel stereo amp with a zero loss vacuum tube input stage and a high bias differentially balanced MOSFET hi current output stage. It produces 250 watts/per channel into an eight-Ohm loudspeaker, 500 watts/channel into four-Ohms, and is stable into 2-Ohms. Sonics are superb and it is our favorite under $15k hybrid amplifier and pure out favorite for many speakers. Sonics are exceptional and compete with amps selling for multiples of its price.
The amp was designed by Bascom King who also was one of the designers of the Constellation amplifiers. It is run hi bias as Class A at lower power outputs. By using only N Channel MOSFETS in its output stage, the BHK Signature
produces a near-perfect balanced waveform without the degradation
inherent in a complimentary design.
We also have the 300 watt mono versions in stock.
