PS Audio BHK Mono 300 Signature Series Mono Amplifier (Pair)

Description

If there is a better performing power amplifier anywhere in the world, we are unaware of it. 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.

• • Zero-loss parallel vacuum tube input stage
  • Fully paralleled inside (not like a traditional bridged approach)
  • Differentially coupled, paralleled, balanced MOSFET output stage
  • All through hole construction (no surface mount parts)
  • RCA Single ended input
  • XLR balanced input
  • 300 watts 8Ω
  • 600 watts 4Ω
  • 1000 watts 2Ω
  • Less than 0.1% thd 20Hz to 20kHz at rated power
  • Damping factor 100 for excellent loudspeaker control
  • Front panel standby button for vacuum tube input
  • -3dB greater than 200kHz
  • Dual, custom, solid copper, gold plated output binding posts
  • Fully balanced from input to output
  • 83 pounds
  • Input 12 volt trigger
  • Easy access for tubes
