Impedance Matched Headphone Output

In-house output transformers provide impedance-matched outputs for low (8–64Ω), mid (65–250Ω), and high (251–600Ω) loads, ensuring natural, balanced sound. With 6.35mm, 4.4mm, and 4-pin XLR outputs, it delivers up to 4500mW per channel for demanding headphones, while the optimized 4.4mm jack suits sensitive IEMs with reduced output and improved S/N performance

Application oriented Output

The 4-pin XLR output is a full-fetched balanced output but the 4.4mm headphone output is optimized for a wider range of applications, including high-sensitivity portable headphones and IEMs:
4-pin XLR (Balanced): UL 4500mW + 4500mW; TR 3000mW + 3000mW
4.4mm (Balanced):UL 1000mW + 1000mW; TR 650mW + 650mW
6.35mm (Single-ended):UL 3500mW + 3500mW; TR 2300mW + 2300mW



Dual Operation Mode – Triode | Ultra-linear


The HA-6A MK2 features a front-panel switch that lets you choose between Triode (TR) and Ultra-linear (UL) operation. Enjoy the lush, smooth presentation of Triode mode or the dynamic, powerful performance of Ultra-linear mode tailored to your music and mood with a single touch.
