To be honest, I haven't listened to my axioms in a long time, since my current dorm room setup does not allow room. With a 30 gallon fish tank and a ton of other stuff...yea.
I've just grown to really like my senns a lot. With a good tube amp, they are just awesome. A lot of the current music I'm listening to is just more suited for senns.
In addition, while the Grado "sound" may be very close to the axiom neutrality in the highs and midrange, the bass is a bit lacking, leaving a sound that doesn't have as much body as the senns. My Axiom setup has a sub, so that takes care of the low end.
My listening preferences change too....just grown to favor what the senns have to offer. I still love the Grados for rock.
