AIYIMA A80 Integrated Amplifier

With its A80, Aiyima unveils a small integrated amplifier packed with audiophile features and components. It's primarily based on an ESS9038Q2M DAC chip and a TPA3255D2 amplifier chip. This enables it to support high-resolution sampling rates up to PCM 32bit 384kHz and DSD256, as well as delivering up to 2x120W of power under 4 ohm with its supplied 48V 5A power supply. Added to this is a QCC3040 Bluetooth receiver chip for reliable wireless connection thanks to AAC, SBC, aptX, aptX LL and aptX codecs.

To complete the package, there's also a handsome color display for easy navigation between the amplifier's various parameters and access to different display modes, such as a vumeter. In terms of connectivity, the amplifier features a full range of digital and analog inputs, including USB-C, Toslink optical, coaxial, RCA and balanced stereo TRS 6.35mm jack, while output is via speaker terminals. As an added bonus, it also features a 12V trigger input and a 3.5mm jack auxiliary output, enabling it to be connected to an active subwoofer or a second amplifier.

Aiyima A80: PFFB circuitry

The Aiyima A80 amplifier benefits from a PFFB (Post Filter FeedBack) circuit that greatly optimizes performance while significantly reducing distortion. It also enables the amplifier to remain stable even in difficult conditions.
