I haven’t got the chance to test the F line, but reviews suggest that they are too analytical, which might be boring to me. I used to have the RHA MA750 before, it turned out too dry and flat for my taste. I prefer just enough bass and it should not bleed into low-mid rather than no bass at allIf you do not need a lot of bass, the F7200 will serve you really well. They are incredibly detailed for a single BA earphone and with a deep-fit you'll get fantastic imaging and instrument separation. Even the lower-end F3100 has quite good instrument separation for the price. The vocal performance is phenomenal as well (basically the F-series on a whole has a specialty in vocal rendition).
