BOSC™ - 150W HiFi Monoblock GaN Audio Amplifier
Small but Packs a Massive Punch
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:
- The amplifier has an easier time controlling the speaker, this produces a more accurate sound.
- Preserves the amplifiers high damping factor (low output impedance).
- Save money on long and expensive speaker cables.

GaN provides the following sonic/sound quality benefits over traditional silicon transistors:
- Less harshness
- Cleaner highs
- Better transparency
- Higher detail
This is because GaN transistors have much better characteristics over their silicon counterparts:
- Increased slew rate
- Reduced ringing
- Faster switching
- Faster overload recovery
Amplifier performance is improved by the use of GaN technology:
- Decreased noise
- Less distortion
- Better transient response
- Higher bandwidth

You read that right. BOSC is an analog switching amplifier. The "d" in class d does not mean digital.
The pulse-width modulation (PWM) is performed completely in the analog domain and is then amplified by the GaN power stages.
This sets BOSC apart from its counterparts that use digital modulation techniques using FPGAs, DSPs, and processors.

Why does it sound so good?
BOSC amplifiers use my proprietary DC coupled, fully balanced dual feedback modulator. This allows the amplifier to be completely balanced from input to output, though the use of bridged GaN power stages.
GaN technology enables BOSC to switch at ~800kHz which is 2-3 times faster than traditional class d amplifiers using silicon transistors. This very fast switching allows for the use of a single-pole LC (inductor and capacitor) filter, which both attenuates the switching frequency by 40dB and allows the amplifier to have no phase shift from DC (0Hz) to 30kHz.
The filter is a very important part of a class d amplifier. BOSC uses oversized very high-quality oxygen-free copper (OFC) inductors and a very high-grade film capacitor.
Having high-quality components will only get you so far; BOSC’s 4-layer PCB is state-of-the-art. It uses a custom stack-up with high-end dielectric material and ENIG (gold) finish.
