Product Information

Setting them to a neutral position is a breeze, and the feedback you get from these detents is pretty satisfying. While I don't claim to be a seasoned audiophile and haven't had the opportunity to audition numerous other amplifiers, I can certainly provide a comparative analysis of these two models. My main concern about keeping the amplifier on all the time is the faint hiss from the speakers (power supply noise), and it keeps the speakers always engaged. If Fosi can fix the speaker load dependency issue and release a true power amp, that will be a good thing. However, if you desire additional features like tone controls and Bluetooth connectivity, then the Fosi Audio BT20A Pro is the obvious choice.

However, there was a subtle difference in bass response with the BT20A Pro, which seemed slightly more pronounced compared to the Aiyima A07. Audiophonics is a company created in 2005, specialized in the distribution and sale of Audio, HiFi, Do It Yourself and electronic products on the internet. If the A07 Max uses the same PBTL method as the data sheet, the speaker connection will never be as described in the manual. These are SMPS and hence your dc output is actually coming from the mains but with very fast switching.Note:The use of audio electronic products is closely related to the size of the speaker and the power supply. Attention au voltage car les premières versions avaient des condensateurs de 50v un peu juste pour utiliser du 48v, pour ma part j'utilise l'alimentation 42v 8,5A Audiophonic sans probleme, cela chauffe tres peu. That almost might be important, and my smartphone has some smart Dolby enhancements, which make the sound better even over bluetooth, so it isn’t exactly as good, but it is close.

The maximum driving power is much higher on A07PRO, and I can almost bottom out on Arylic A50+, while I stay well below 10 o’clock on A07PRO. I've seen laptops with 3-pin power supplies too, and it does make me wonder why these amplifiers use 2-pin plugs.En toute circonstance l'impact du grave est impressionnant et celui-ci reste d'une netteté exemplaire. The EQ wheels are super useful, you can define how much weight and bass you want in your music, and how much treble you want as well, the sound can be smoother or crisper, and you can get quite a bit of bass and impact. The A07 was the first small amp I'd bought since my decade-old SMSL SA-50s, and it was an improvement, which the A07 MAX takes further still. AIYIMA A07PRO looks far more similar to the likes of Fosi Audio AMPs, than it looks similar to other AIYIMA products, such as the D03 Amplifier I reviewed in the past. The sound is extremely powerful, the unit works as intended, and regardless of the volume, it does not burn down.
