5 YEAR WARRANTY AND 30 DAY MONEY BACK GUARANTEE

As a top 10 audio brand in China, Tonewinner has 30+ years of experience in designing and manufacturing acoustic products.

Main Features
Class A circuit that adopts full balance, full symmetry, differential input to differential BTL power output.

Both left and right channels adopt independent power supply, which boost the channel seperation to the highest degree.

Output power 300W/8Ω each channel. It uses 1,200W high quality toroidal transformer and audio special capacitor up to 180,000uF. It also uses high power transistors to parallel output, offering 60A current output.

High end aluminum chassis, rigorous intenal layout, and strong anti-interference ability.

Specially gold plated IC socket for audiophiles to replace operational amplifier.

lt adopts Tonewinner's patented technology: High/low voltage power supply intelligently switch management. It can meet the needs for Hi-Fi Class A power output, and also conforms to energy conservation and environment protection concept (patented number: ZL201420783891.8).

Multiple circuit protection: short circuit protection, overheating protection and DC protection.
