Very vice looking pair you got there. I absolutely adore my set, anytime i go back to the 80i's i give up after 10-15mins and go back to the MS1's, they are that much better. I also dont understand how people say they lack bass, IMO they have more full bodied low end than the 80i's, and similar high end without being piercing and fatiguing. Infact when i first got them the better low end had me sold within the first minute of listening, they really are that much better than the 80i's. Only other can that get as much use are the HD650's, and dare i say it i think i prefer the MS1's.
I have a set of 225i's on the way, that should be an interesting comparison. Though Semicoln's comment above has me a little concerned...
