I dont take GE graphs very seriously, theyre messy at times due to their weird compensations. Wish they provided raw results.
UM3X does have a considerable amount more. Thats like a 7-8db boost.
I thought the 161 had a bit much bass, but the subbass is highly welcomed. Having more 100-300hz bass compromises midrange transparency for thickness/warmth.
Good information to know. I agree entirely with the 100-300 as the main culprit, but too much sub-bass can also compromise things (in bass mostly, but can also extend into midrange compromise).
