PS Audio BHK 300 Amp Black

When you are unwilling to compromise performance we offer the BHK 300 Signature 300 watt Monoblock power amplifiers. They are among a rare handful of amplifiers capable of uncovering music's rich tapestry in a lush, uncompromised, effortless presentation.

The audio performance and build quality of the Signature 300 series has been refined, honed, and polished over the past half century of design work by industry legend, Bascom H. King.

They are mono block amplifiers that produce 300 watts into 8Ω, 600 into 4Ω, and a whopping 1,000 watts into 2Ω. The BHK Signature 300 Monoblock designs are built upon two proven topologies: a zero-loss vacuum tube input stage coupled to a high bias differentially balanced MOSFET output.

If you are uncomfortable with compromise and seek the finest performance, reliability, and build quality, the BHK Signature 300 series is a perfect fit that can drive any loudspeaker to musical perfection.

The 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 BHK Signature 300 Mono 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 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.

A power amplifier’s input stage is a critical interface in the quest to preserve music’s essential details and vacuum tubes do it best. Hand matched pairs of Russian Gold Lion 6922s provide the perfect interface between the delicate musical transitions output by the DAC or preamplifier, transferring it without loss to the MOSFET output power stage and eventually the loudspeakers.
The hybrid approach used in the BHK Signature takes advantage of the best traits technology has to offer, unavailable in traditional solid state or tube designs. While vacuum tubes are the perfect input stage, they cannot make the same claim on a power amplifier's output. Conversely, solid state designs are correct for output stages, but suffer when used as inputs. Only a hybrid approach takes advantage of the best in both disciplines.

A power amplifier connects its reservoir of energy to the loudspeaker through a type of valve (solid state or vacuum tube) controlled by the input stage. If the input stage has done a good job of preserving music's subtle details, textures, timing and phase information, transferring it without loss to the power stage and eventually the loudspeakers is best handled by a tube-like solid state device known as a MOSFET.

Not all MOSFETs are the same, their differences characterized by their relationship with the input signal and the power supply driving them: N-types for the positive going signals, P-types for negative. N-types have lower distortion and perform better than P-types but N-channel-only amplifiers are rare. Using only N Channel MOSFETS in its output stage, the BHK Signature produces a near-perfect balanced waveform without the degradation inherent in a complementary design.
