Description

LD H1 is a tube-transistor hybrid, fully balanced amp.

The LD H1 uses a purely discrete circuit that does not ues any integrated circuits.

The pre-stage tube uses the NOS Sylnavia tubes 6SN7.

The transistor part runs a fully discrete, fully symmetrical, pure class A amp circuit, and it has better transient response and lower distortion than the asymmetric circuit, which makes the sound quality sweet.

The LD H1 features a dual mono structure that is designed independently from the power supply to each amplifier to avoid interference.

The filter capacitor of LD H1 uses Philips’ famous BC dedicated audio filter electrolytic capacitor and coupling capacitor. It uses Mundorf MCap EVO dedicated audio coupling capacitors.
