PS Audio BHK Mono 600 Power Amplifier (ON SALE)

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 600 has no peer. The Signature 600 monoblock amplifier is a no holds barred upgrade from its series-mate, the BHK300. Its 1.6KVA power transformer is twice the size of the 300 and we didn't stop there. The 600's 300,000uF bank of low-ESR high-grade audio power supplies caps is double that of the 300 as are doubled the output MOSFETs producing some of the lowest output impedance and highest damping factors we have ever measured. The control this amplifier has over the music and the system is unrivaled.
