Its just that the RS-2 sounded more like the 225 then the HF-1/RS-1 smooth warm dark sound (which is what I prefer) And I do like the 225s and I could definitely live with them but they're still missing a whole lot in the bass region.
I know you had the 325i's before these. Obviously the high end is lacking compared to them but are they lacking in a way that they dont sound like a grado or they just have less treble then you want?
I've been using the 414 pads almost since I got the 225s and I've heard the black 325 (woodied by nate) and it sounded good, a bit better then the 225s woodied.
