The RS1s kind of fell of the map for me, which doesn't really mean anything given how slow it takes for a headphone purchase to go from an idea to a reality for me.  From what I've read, it seems like I'd be paying a couple hundred dollars for some very slight tweaks to give it a less aggressive sound sig than the 325is.  Is this true, or is the RS-1 flat-out a better performer(dynamics, soundstage, simbilance, bass quality, separation, etc)
 
Another way of questioning it, to me, is whether Grado came up with the RS-1, then decided to alter the sound-signature in less pleasing ways so they can have lesser models
