The Aiyima A07 is a small, simple, powerful, efficient and affordable Class D amplifier, ideal for setting up an audio system that requires a lot of power input. These are SMPS and hence your dc output is actually coming from the mains but with very fast switching. Test of AIYIMA A07 by Audio Science Review " These TPA3255 based amps seem to have good bones in them, producing above average performance for peanuts. These TPA3255 based amps seem to have good bones in them, producing above average performance for peanuts.

Users can enhance or attenuate the high and low frequencies according to their personal preferences until they achieve the best sense of experience. If you are looking right at the amp on one's desk or shelf, that's less important - but I still think that Fosi wins the ergonomics award for the knob. To level the playing field, I adjusted the Aiyima A07's volume to 50% and the BT20A Pro's to around 75% until they sounded equally loud. Possesseur d'un Aiyima A07 et d'un "A07 PLUS", il faut reconnaitre que cet Aiyima A07 MAX est déroutant et décevant. The LPF adopts the United States ITW military non-inductive melaleuca inductance coupling capacitor, and the input coupling capacitor adopts ELNA R2A and Nichicon MUSE Goddess advanced audio new line capacitors, with a reasonable design, the output treble is clear and bright, the bass is powerful, and the elasticity is high.I keep recommending that Fosi develop mono-blocks or a stereo product (straight amp, no V/C) to compete with the Hypex-based power amps.

You can avoid this by turning both wheels at max, this does not add any kind of distortion or problems, and the experience is super pleasing. KLH Model Five can climb down nicely powered by A07 PRO, but the bass can be a bit overwhelming if I use the bass wheel past 3 o’clock. Compatible with a variety of op amp chips:A07 amplifier has a rich midrange,If you want to replace the NE5532 chip and experience a different sound, you can replace op amp chips: OPA2604, OPA2134, LM4562, JRC5532, etc.To my surprise, it presents zero hissing, zero background noise, my speakers are more silent with it than with Cyrus One Cast, and this is a huge achievement for an entry-level stereo Amplifier. That said, I wonder if these passive chip-amp designs are more limited with overall hw design or with internal temperature. Note: these measurements have not been independently confirmed yet but they are inline with the expectation based on previous results. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. If you look on the internet, there is a data sheet published that shows exactly how much power this amplifier has, and it is in line with other entry-level AMPs, you can check it here.
