Decades of classics, why do we still play the LM1875 circuit? Because the circuit is classic, the sound is durable, the sound is bold, and the aftertaste is endless. The most important thing is that the price is high.

It adopts an integrated design, integrates rectification and filtering, and 1237 speaker protection circuit, no need to connect external power supply board and protection board, in one step.

The protection circuit composed of a relay and UPC1237 has the function of switching machine anti-shock and mid-point DC output protection, which can effectively protect your expensive speakers.

Selected materials: high-quality capacitor array is used for power supply filtering. Lower internal resistance, as well as special Japanese Ina ELNA audio capacitors, low leakage current, low ESR charging and discharging speed is very fast, low frequency thick, high frequency is the foundation. And the use of oxygen-free copper inductors, eliminating interference and noise, the quality is purer and more natural.
