Thank you Flash. You indeed know what an EQ is for. I agree that a real EQ hardware set up is better but to be honest they are a bit extreme for most people. I would love one though. It would make fine tuning the home cinema a whole lot better.
Anyway, to get back on topic. Anyone after a quality audio player for their PC should get Foobar2000. It will make a difference even if you are using the monitor speakers. I'm so glad that 7Force recommended it.
