Description

The M4 circuit is baes on SF60: this British circuit is incredible. Reproduce music melodies that are infinitely immersive and intoxicating. The pure and natural sound quality is fully integrated into the circuit. Compared to the Aoli 8000A, the Aoli 8000A is significantly two levels higher, especially in terms of mid to high frequency layering and delicacy.
The effect of this amplifier is much better than those using NECUPC2581V as the driving transistor, especially the mid-range is much more comfortable to listen to, and more importantly, the input operational amplifier can be replaced to achieve the fun and enjoyment of tone matching and upgrading! If the heat dissipation is sufficient, the machine can also be adjusted to pure Class A output! The product comes with complete overcurrent protection, delay protection, and output DC protection to ensure the safety of expensive speakers.
