In life we admire “heart.” When we say someone has heart we mean passion, spirit, fortitude. And we applaud it. While the amplifier is the brawn behind every successful music and movie presentation, it is also the heart! Its role is as crucial as that of the speakers in its ability to render delicate musical detail one moment and deliver room-shaking explosions the next. The most exquisite piece of music falls flat without clean, quiet power to sustain it through to its natural, musical ebb. Movie special effects require an inordinate supply of stable, high current power to give visceral credibility to the “special” aspect of each effect! In fact, all truly successful sound reproduction requires “heart.” The heart of an amplifier rests with its design and it is here that P2 and P5 amplifiers reveal their high-end lineage: multi-layered, hand-designed circuit boards with thick copper traces; rugged, independent power supplies with tuned toroidal power transformers for each amplifier channel; fourteen rugged bipolar output devices per channel; custom-designed convection-cooled heatsinks with serrated fins; a “no-fuse” design strategy. And the list goes on.
P Series amplifiers are the cleanest, quietest amplifiers in the industry. Each amplifier channel features two separate and autonomous power supplies fed from separate transformer windings. The amplifiers are thus able to deliver stable, continuous power at maximum output, regardless of the number of channels being driven.
While some amplifiers tend to oscillate when driving lower impedance loads, the P2 and P5 remain perfectly stable under all conditions. If pushed into clipping, the proprietary anti-saturation tracking power supply circuit takes over to ensure a seamless recovery.
Since the use of a regulated power supply in the driver stage removes noise emitted by the bridge rectifier (often heard as an audible hum at 120 Hz and its harmonics), the P2 and P5 achieve an utterly silent noise floor.
