E400 is suitable for driving many kinds of difficult headphone such as T1 / HD800/8800/9900 etc.
The 2nd function is preamplification, it work also like a preamplifier, the both function have the same circuit and tubes past for both function.
It has very high SNR, no noise even using with small earphone.
High or low impdence swith to match with your headphone impedence, suitable for 15-150ohm lower impedence headphone or 160-600ohm high impedence headphone
Provide high quality sound with no audio rendering. Benefit from its very high resolving power, it can perfectly show up every detail and the complexity of symphony.
Performance of E400 is much more outstanding than predecessor products. Much lower price than British Sugden Sugden Masterclass HA – 4 but with even better performance
Quiet background voice appears exquisite and smooth, for 99.9% of the headphones on the market.
