Aerial 10t or KEF 107 for "vintage" speaker?

I'm considering picking up a pair of Aerial 10t or KEF 107 for my main set up and am hoping a'gon members can help me with a few questions.

I can hear the 10t before purchase, but not the KEF, and while the designs seem similar, my research found only general comments of "they sound great" or "are great speakers" with not much detail on how each speaker sounds.

I tend to prefer a smoother, laid back sound, and generally, most of my critical listening is done at lower volume, so the ability to sound good at lower volume is key for me. My Mc pre has adjustible loudness control (gasp) and I've used it despite being viewed as a heretic.

As for amplification, I understand the Aerial " needs a bazillion watts" and enough current to power a monorail, so I'd probably be looking to amp swap if I go that route. I'm currently using a Conrad Johnson MF2250 (125w into 8ohm, close to 200 into 4ohm, but probably not enough current).

My main reservation on the KEF is the Kube reliabilty after all these years. It seems to be a critical component, and since most pairs don't have a Kube included, I'm assuming they've failed.
I do like that they vent out the top and not rear like the Aerial, since I'll only have a foot from the back wall to place. I have loads of space to either side.

Can anyone share thoughts on how either of these speakers sound?
