Hi Dan
Thanks for your posting. I also owned a great pair of 104.2s for about 25 years - loved them, and sometimes have wished I kept them instead of selling them. Great speaker, and the 3.1 is in many ways a modern update of it. D'Appolito midrange array, but with better high end and low end - perhaps not quite as good midrange, but the 104.2 was a tough act to follow in that regard.
Have been fiddling around with the Audyssey and have gotten what seems to be a good (not radical) EQ - The NAD has a version of the EQ that is still warmer sounding than the flat EQ, but that makes up for upper midrange-low treble depression in the 3.1. With that EQ program engaged, the speaker sounds remarkably neutral, and interestingly, it trims the bass back just a bit, perhaps too much so for my tastes, but it shows that there is the standard mid-bass hump in the speaker's response when near any kind of boundary. My fiancee likes the bigger bass of the stock stereo without the Audyssey room response correction. but there is no accounting for taste!
I suspect that the 3.5 will fill that area in, but with the EQ, I feel I already have that. And I also spent some time recently dampening the speaker frame resonances, so that now played really loud, there is little noise coming from the metal frame. Still not sure that those frame resonances are truly audible, but compared to a box from B&W or KEF, this thing was a bit of a 'gong' in its stock form.
