See my prev post. It depends on the source. If you have a good amp/dac then the 325s are better at taking advantage of it. The 225s can get close with different mods (flats or tape mod) but they will never have the depth and detail of the 325s.
Yeah-I think that's about right. I'm using the tap mods and the 325 had more depth and detail-question of degrees and price point really.
