Hi there

I have been enjoying my Rockboxxed H140 driving directly into my Headphones - Sennheiser HD580's but wanted to try using one of my headphone amps - RSA SR71 and Heavily modified X-cans v1.

In both cases the sound was a great disappointment - worse than feeding the headphones direct from the player. The volume control doesnt seem to be diabled either which surprised me.

What I am doing wrong and how can I fix it please?
