Fast delivery, good quality product, mono power in bridges about 2x 400 Rms tested with a Pioneer TS-W306C speaker and it plays loudly. The speaker has a large suspension range, the bass is clear, powerful, and clean. I am pleasantly surprised because I didn't expect the amplifier to have such power. I RECOMMEND!

Unbeatable value for money. BJT marked "TOSIHBA" not Toshiba, but still much better than car radios, crossover LPF ok, HPF not very effective. Overall, for the price paid, I think it's impossible to find better.

I never thought it would work this well, I'm really not disappointed, I will order more.

Overall, a good to very good device for this price. For the technicians among us, a few tips: Check the solder side and re-solder the power semiconductor. Solder was omitted at some points - see pictures Power measurement showed 50-60 watts RMS at 8 ohms per channel. If the amp should deliver more at 4 ohms, the switching power supply/ELKOs are under-rated. Preamp ICs are 4558 as well as a lot of 2SA1015/2SC1815 - also the drivers, Toshiba 2SA1941/2SC5198 power amplifier. So all high-quality brand components that are also found in well-known devices. The circuit board layout is clean and organized, workmanship (sheet metal screws) grade 2. Good features with BassBoost and a separate woofer output for the rear Conclusion: Class amp for narrow gauge - BUY

Great amplifier for the money, pcb assembly was reasonable also.
