Well last night I tought it was a burn-in issue. But obviously not. My Bravo audio v2 gains music volume indeed. But with a crappy presentation. Transparency and sound stage doesn't mean anything with this product. I listen much more good equipment so probably I am not so forgiveness to this. But truth is truth. My emu 202 headphone out has less power but better quality than this. Is there any chance to make it listenable with tube rolling?
