DEMO 931 Headphone amp
Vores demo hovedtelefon forstærker
Den lille hovedtelefonforstærker fra Trilogy Audio.
Ren single ended klasse A med en overdimensioneret lineær strømforsyning.
Det giver en god lyd med masser af overskud.
Like its bigger brother the 933, the audio circuit operates in pure single ended Class A with active constant current sources. Each channel has a single continuously biased output device. The main benefits of this topology are that the output is free from crossover distortion, and the device is held at a constant temperature.
An oversized linear power supply is implemented with a custom low flux density toroidal transformer and low ESR reservoir capacitors. This provides a low noise supply for the active circuitry with generous operating headroom.
All these elements combine to give excellent small signal resolution while maintaining good drive capability for any type of headphone.
