The standard setup is very good to be fair.
But obviously with a cone you'll get a load more noise which is always good!!! The debate of foam vs cotton is a big one, foam allows more air through but cotton provides better filtration. I'm sure I've got that the right way around hahaha!!! Paper has the highest filtration rate but is the most restrictive. There's some really good videos on You Tube that some American guy has done comparing six or seven different filters, I'd link it but I'm on the iPhone at the moment.
