I've had my eye on the Etymotic hf5 for a while now. In the past the most neutral cans I've owned and adored were grado 225i and mee a161. I'm just a little concerned about the lack of bass in the hf5's or is that only bass heads complaining. The 225 always had that not enough bass in reviews but I thought they were great. I like analytical, somewhat neutral, and no muddied sounds..... Do you think the hf5 would fit the bill compared to the shure se215, if so what about the hf2's?
