PS Audio BHK Mono 300 Power Amplifier
The new PS Audio BHK Signature 300 Mono Block Power Amplifier is one of only a rare handful capable of uncovering music’s rich tapestry in a lush, uncompromised, effortless presentation. If you haven’t any barriers to perfection, the BHK 300s are perfect for any size system in the world, producing a minimum of 300 watts into 8Ω, a minimum 600 watts into 4Ω, and an astonishing 1000 watts into 2Ω. Enough linear amplifier power to bring life to music as you’ve only experienced with live music.
The BHK Mono 300 features a hybrid vacuum tube/MOSFET design of the BHK Signature Amplifiers provides stunning musical performance through any loudspeaker.The Signature 300 Mono doubles the output current of the 250 Stereo, and doubles the tubes, power supplies, transistors, capacitors and resistors. The results are hard to put into words. Your first listen to these extraordinary monoblock amplifiers will likely be a revelation. For perhaps the first time you’ll discover all that has been long buried in your musical collection. You’ll know this amp was the right choice from the very first note you play.
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 300 has no peer. The Signature 300 monoblock amplifier produces 300 watts into an 8Ω loudspeaker, 600 watts into 4Ω, and 1,000 watts into 2Ω, providing unfettered and unrestricted dynamics and musical ecstacy that only a rare few are able to enjoy.
