Orchard Audio – 2 x BOSC™ Monoblock Amp

From £1,295.00£1,370.00

BOSC monoblock audio power amplifiers were conceptualized to provide the listener with a truly life-like musical experience, presented with every significant detail intact, in order to convey an emotional connection to the music.

BOSC amps use the latest state-of-the-art electronics, including gallium nitride (GaN) technology to achieve ultra-high performance in an easy-to-use small package that will blend into any decor.

BOSC™ Inline Amp

Awkward packaging… Yes, but with good reason. The amps are made small and with connectors on opposite sides, allowing you to place the amplifier right behind the speaker. This has multiple benefits:

  1. The amplifier has an easier time controlling the speaker, this produces a more accurate sound.
  2. Preserves the amplifiers high damping factor (low output impedance).
  3. Save money on long and expensive speaker cables.
