Hey guys!

I've just invested in some decent Sennheiser earphones (never use stock ones!) and I'm now looking for a music app to match! I've found the stock music player lacks the dynamic range for the different types of music I listen to. My main genres are progressive rock, rock, techno/house and occasional classical. I've dabbled with the trial of Power Amp and was quite impressed, but wanted to know what other people have tried and gone with before I part with my meagre amount of money! Audiophiles, lend me your ears!!!

What are your recommendations/thoughts?

Cheers guys.
