Why we love it
  • High-fidelity sound quality assured.
  • Advanced cooling for stability.
  • Supports multiple input types.
Main Highlights
  • Mini Monoblock Amplifier: Crafted for HiFi audiophiles, the V3 Mono allows you to drive a single passive speaker with one amp, delivering up to 240W @4Ω of rated power. It offers the flexibility to build your home audio 2/3/4/5-channel system effortlessly. The V3 Mono can serve as a power amplifier for multi-channel AVRs, complementing the output power to easily drive high-power speakers in home theater systems.
  • Innovative Cutting-Edge Technology: Fosi Audio has achieved a technological breakthrough through independent research and development by applying PFFB (Post-Filter Feedback) technology to the V3 Mono for the first time. This effectively overcomes the common load dependency issues of Class-D amplifiers, improving distortion and enhancing frequency response, thereby significantly enhancing sound quality and performance.
  • Audiophile-Grade Components: The V3 Mono incorporates the high-end TPA3255 Class-D amp chip, paired with well-known components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors, etc. Additionally, it features an upgraded four-layer PCB. This combination not only ensures high power output but also achieves a THD as low as 0.006%, a SINAD of 101dB, and an SNR of 123dB.
  • Advanced Cooling: Utilizing Fosi Audio's pioneering full-body heat dissipation design, the TPA3255 amplifier chip is placed at the bottom and tightly integrated with the chassis, allowing heat to be effectively dissipated through the casing. Coupled with dual side ventilation holes that enhance internal airflow, this ensures the V3 Mono can deliver stable, high-power output over extended periods.
  • User-Friendly Design: Supports both XLR/¼" TRS balanced and RCA single-ended(with gain selection) inputs, with an easy toggle switch for selection. Additionally, it features an auto power/signal sensing mode to enhance energy efficiency. You can also customize your preferred sound signature by replacing the stock NE5532 op-amps, supporting DIP8 dual discrete op-amps such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, and more.

Why we love it
  • Exceptional sound clarity achieved.
  • Flexible sound tuning options available.
  • Rich connectivity for all devices.
Main Highlights
  • High-end components: The A20 hifi stereo amplifier uses the TPA3255 Class D amplifier chip and is equipped with German WIMA, Japanese Genicon, Ruby capacitors and gold-plated terminals. It delivers a maximum output power of 300 watts at 4 ohms (this requires a 48V 10A power supply), ensuring exceptional sound quality while achieving a signal-to-noise ratio (SNR) of up to 116dB and a distortion rate as low as 0.002%, resulting in extremely clear and low-distortion audio performance.
  • HPF High Pass Filter Adjustment: The TPA3255 desktop amplifier features an adjustable high pass filter (HPF) with an adjustable range of 60-200Hz. It optimises mid and high frequencies for clear and transparent mid and high tones while minimising low frequency interference. It enhances clarity and creates a dynamic sound field, making it a great choice for home stereo and home theatre audio systems.
  • Rich connectivity options: This 2.1 fully balanced stereo amplifier is equipped with RCA/XLR input interfaces and a 12V trigger. Balanced inputs effectively reduce noise, providing pure stereo output, and restore true sound quality through independent low-frequency drivers. The 12V trigger input interface enables synchronised control with other devices, simplifying the power switch operation process without the need for separate operations.
  • Enhanced sound quality: The A20 Class D amplifier uses two LME49720 (plug-in) and seven NE5532 (surface-mount) operational amplifier chips to achieve ultra-low distortion, low noise, and extremely transparent sound quality without colouration. Different audio experiences: You can replace the LME49720 operational amplifier chip with LM4562, NE5532, OPA2604, OPA2134, JRC5532, Muse02, etc., to precisely tune the sound quality to perfection.
  • BYPASS Function: The A20 Integrated Amplifier features a bypass mode, which reduces audio quality loss, making it a high-fidelity pure power amplifier. Note: In bypass mode, the amplifier volume is set to maximum. Before switching to bypass mode, please lower the volume at the source end to avoid hearing damage and speaker damage. This mode has a memory function; to exit, press and hold for three seconds.
  • PFFB circuit design: A20 uses PFFB (post-filter feedback) technology to effectively overcome the common load dependence problem of Class D amplifiers, improve distortion, enhance frequency response, and thus greatly improve sound quality and performance.

Why we love it
  • High-quality sound performance.
  • Cutting-edge amplifier technology.
  • Advanced cooling design.
Main Highlights
  • Mini Monoblock Amplifier: Crafted for HiFi audiophiles, the V3 Mono allows you to drive a single passive speaker with one amp, delivering up to 240W @4Ω of rated power. It offers the flexibility to build your home audio 2/3/4/5-channel system effortlessly. The V3 Mono can serve as a power amplifier for multi-channel AVRs, complementing the output power to easily drive high-power speakers in home theater systems.
  • Innovative Cutting-Edge Technology: Fosi Audio has achieved a technological breakthrough through independent research and development by applying PFFB (Post-Filter Feedback) technology to the V3 Mono for the first time. This effectively overcomes the common load dependency issues of Class-D amplifiers, improving distortion and enhancing frequency response, thereby significantly enhancing sound quality and performance.
  • Audiophile-Grade Components: The V3 Mono incorporates the high-end TPA3255 Class-D amp chip, paired with well-known components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors, etc. Additionally, it features an upgraded four-layer PCB. This combination not only ensures high power output but also achieves a THD as low as 0.006%, a SINAD of 101dB, and an SNR of 123dB.
  • Advanced Cooling: Utilizing Fosi Audio's pioneering full-body heat dissipation design, the TPA3255 amplifier chip is placed at the bottom and tightly integrated with the chassis, allowing heat to be effectively dissipated through the casing. Coupled with dual side ventilation holes that enhance internal airflow, this ensures the V3 Mono can deliver stable, high-power output over extended periods.
  • User-Friendly Design: Supports both XLR/¼" TRS balanced and RCA single-ended(with gain selection) inputs, with an easy toggle switch for selection. Additionally, it features an auto power/signal sensing mode to enhance energy efficiency. You can also customize your preferred sound signature by replacing the stock NE5532 op-amps, supporting DIP8 dual discrete op-amps such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, and more.
