MASCINI - 250Watt Audiophile GaN Class-D Stereo Power Amplifier SILVER

Description

This 250W (in 8 Ohm) per Channel stereo power amplifier based on Gallium Nitride (GaN) power FETs with significantly higher power density over silicon MOSFETs, was created with pure sound quality in mind to drive the most challenging loads - even down to 2 Ohm:

• Superior audio performance, such as better SNR, lower THD+N, and lower T-IMD, because of GaN’s cleaner switching and shorter deadtime
• Super fast PWM switching of approx 0.65MHz, enabling a simple output filter with low distortion
• Very high efficiency up to 97%, resulting in very low heat at full power output, and compact overall size
• Custom 500W LLC power supply
• Discretely build auxiliary power supplies for powering the various amplifier stages, independent from the main end-stage power
• Use of high grade audiophile components, such as MELF resistors, top-quality audiophile opamps, and gold plated connectors for the best sounding result
• Both unbalanced (RCA) and balanced (XLR) line-level inputs
• 4-Layer Component Board design with 2 oz thick copper and fully optimized trace lengths for best conductivity, lowest parasitic induction, and reduced EMI
• Internal cabling with 10 to 14 AWG oxygen free copper wire for near lossless power transmission
• High (+34dB Max) gain allows direct line-level input (no preamp required)
• Fixed gain control ranging from +34dB to +16dB in 8 quantized steps
• Premium Chassis: Housed in a precision engineered, full aluminum casing with a high quality brushed anodized finish, available in Silver or Sleek Black.
