When I went to bozebuttons's house for a mini-meet, I got to spend a lot of time with the high end grados (the vintage RS-1 and the HP-1/2/3 especially) and I realized that the 225s doesn't have the sound that I want nor can it scale the same way that the other two phones can.
So, I'm trying to get less shrill treble, a more fuller sound (esp in the low end) with better extension in the lows and a slightly bigger soundstage that keeps the grado sound. Does that sound like the MS-2i's?
PS. and my 225s are woodied, which does fix the problem (with the bass and the soundstage) a small amount but not enough to my liking.
