Manufactured specifically for the UK market with custom 240V transformers, this dual-chassis flagship separates the sensitive signal path from the power supply, achieving ultra-low background noise and extreme power stability.\u003c\/p\u003e\n\n\u003cp\u003eThe MK3 revision introduces a completely upgraded third-generation circuit topology featuring wide-bandwidth EI output transformers, a custom toroidal power transformer, and premium Danish DUELUND coupling capacitors. It transitions to GZ34 \/ 5AR4 tube rectification for enhanced flexibility when tube-rolling. With three impedance modes (Low, Medium, High) and an attenuated 4.4mm balanced output, the HA-300 MK3 seamlessly drives everything from ultra-sensitive IEMs up to demanding full-sized planar magnetic headphones and desktop loudspeakers.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp;
