The new PS Audio BHK Signature 250 Amplifier combines a vacuum tube input with a powerful MOSFET output capable of 250/500 watts per channel. When cost-no-object performance is the goal there are a rare handful of power amplifiers capable of transporting listeners into a musical space few are able to enjoy. The BHK Signature 250 is one such amplifier. Lush, gorgeous, powerful, revealing, hand built, perfect. If you are uncomfortable with compromise and seek the finest performance, reliability, and build quality in a single-chassis format, the BHK Signature 250 is a perfect fit.
Nothing in the design of a power amplifier is more important than its input stage when preserving music’s finest nuances. In the BHK Signature, a vacuum tube serves as the perfect interface between the preamplifier and MOSFET output stage. This hybrid approach offers stunning musical performance and unrivaled, effortless drive to the speaker. The Signature 250 Stereo Amplifier is the ultimate choice when a single chassis solution is required.
The BHK Signature 250 Stereo Amplifier produces 250 watts/ channel into an eight-Ohm loudspeaker, 500 watts/channel into four-Ohms, and stable into 2-Ohms; enough power to satisfy even the hungriest of loads. Use this amplifier as the bedrock of your high-performance audio or home theater system. The BHK 250 provides the finest performance, reliability and build quality possible, in a single chassis format.
The importance of the power amplifier in the 2-channel system chain cannot be overstated, yet it's often overlooked. It's the rare few music lovers that truly appreciate the power amp's critical role in preserving music's nuanced details, because most amplifiers fail to preserve them. Overtones from plucked instruments, subtle cues defining placement, depth, soundstage width, and transient decays are often lost in the power amplifier. Suddenly revealed are the tiniest of details that now ring clear through the BHK, perfectly preserved through its low feedback, vacuum tube and MOSFET design. When it comes to musically controlling and powering loudspeakers, the BHK Signature has few peers at any price. The stereo Signature 250 produces 250 watts/per channel into an eight-Ohm loudspeaker, 500 watts/channel into four-Ohms, and stable into 2-Ohms; enough power to satisfy even the hungriest of loads.
