Excellent design: The A80 DCA amplifier is full of technology, a combination of fashion and retro, with an electronic UV display design, spectrum analyzer display, and 3 different display options, you can switch the mode you want. It can clearly display input status and volume and other information in real time, especially in scenes such as playing games, parties, etc., and enjoying classic songs, showing very good dynamic image effects.
PFFB circuit design: A80 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.
Compatible with a wide range of op-amp chips: If you want to personalise your audio experience with the A80's op-amp rolling feature, you can try using a compatible eight-pin dual op-amp chip, such as:RT3609SM, OPA2604, OPA2134, LM4562, JRC5532, OP275GSZ, OPA1612 and so on.Note: It is to replace the op-amp chip of the second board underneath.
Please note: For the analogue audio input ports on the A80 amplifier, if using a 3.5mm jack connected to a computer, a 3.5mm to RCA adapter cable is required. Please purchase a 3.5mm to RCA conversion cable separately. When using fibre optic input, please inspect your fibre optic cable for defects and verify that your equipment, parameters, interfaces, and specifications are not incompatible.

AIYIMA A20 Balanced Stereo Amplifier with HPF Adjustment Home HiFi 2.0/2.1 TPA3255 Integrated Power Amplifier desktop class D amplifier PFFB with RCA/XLR Input &12V Trigger-in for Passive Speakers
AIYIMA
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.

AIYIMA A07 MAX 2 Channel Stereo Amplifier Home Audio 300 Watts x2 Power TPA3255 Class D Mini Speaker Amp Bridgeable Mono Stereo Desktop Amplifier 600Watt With 3.5mm Output Integrated HiFi Amp
AIYIMA
Why we love it
Superior Audio Quality with TI.
High-quality Japanese and German components.
Innovative bridged mono design.
Main Highlights
Superior Audio Quality：AIYIMA A07 MAX Mini Hifi amplifier uses TI TPA3255 high-performance, low-distortion Class D amplifier chip and NE5532 operational amplifier chip, wafer resistors. Ensure excellent sound quality and stable performance, showing the richness and clarity of music.
High-quality audio components: The mini home audio amplifier uses Japanese capacitors, ELNA and German WIMA capacitors, as well as IT power management chips, large binding posts, and positive and negative power supplies. Create excellent sound quality, more stable in large dynamic music, and stronger sound layering.
Innovative bridged mono design: AIYIMA A07 MAX is a bridgeable mono/stereo desktop amplifier that can be easily set up by simply flipping the function switch on the bottom of the machine. Easily drives 2-8 ohms, comes with 36V6A power supply, Stereo Max output power 8 ohms 94 watts x2, Mono Max output power 8 ohms 118 watts.(Note: You need a more powerful power supply to get the MAX 300W x2 power output, such as 48V/10A).
Excellent design: The amplifier adopts a mini-shape design and combines an air circulation design concept. Ventilation holes on the sides and bottom of the case effectively dissipate heat while preventing damage to internal parts, ensuring optimal performance. The compact body is ideal for desktop use, home audio systems, and office work settings.
Compatible with a variety of operational amplifier chips: A07max power amplifier has rich sound. If you want to experience different sounds, you can replace the operational amplifier chips: OPA2604AP, OPA2134, MUSEO1/02/03, LME49720NA, LM4562, AD827AQ, etc.
Note: Pre-out" level is not controlled by the volume control because the A07MAX amplifier is not an integrated amplifier, so the sound cannot be adjusted when you connect it to "Pre-out".A07 MAX machine preheating an hour or so, the sound quality tone better!
Note: The TPA3255 is a high-performance Class D audio amplifier chip whose final power output is closely dependent on the power supply configuration. Using an incompatible or non-compliant power adapter may result in inconsistent output power levels or insufficient power causing device protection (incompatibility).

Note: The TPA3255 is a high-performance Class D audio amplifier chip whose final power output is closely dependent on the power supply configuration. Using an incompatible or non-compliant power adapter may result in inconsistent output power levels or insufficient power causing device protection (incompatibility).
