Trevor, agreed the M5s are very nice. I am curious how, or if, you are taming the bass. I've had no luck with bass taming for M3s, M5s or M100s in anyone's room. My buddy has his M100 ports plugged in his living room. He loves them BTW.

M2 bookshelf and OW, M50 and actives are no problem. Ditto with 160 and QS10.
