kheine - Yes.
There's a long story about the bottom inputs, but we can summarize that my design goal of furniture elegance without electronic clutter, has been less than popular.
Here are some considerations for your move that include the fruit of my recent redevelopment work. I believe that the 'wire as waveguide' construct is more functional than 'wire as electron conductor'. Sound quality will be improved more by managing propagation fields than by making lower resistance connections. I now land firmly on banana plugs rather than spades or bare wire. I also remove any excess conductive mass in the signal propagation path to reduce eddy currents. Therefore I judge your 3.6 plastic capped binding posts as sonically superior to the later large metal lugs and knobs. But greater improvement can be made by streamlining the signal path further by repositioning the inputs away from the electrically conductive input panel and using a straight-line, a low mass terminal system directly through the cabinet (bottom or) back. There is something to be said for positioning them at the back edge of the bottom, facing down. (I suspect you would rather not.)
I highly recommend the Electra connectors from GR Research. In fact, as a stand-alone improvement I suspect their ise will bring the largest SQ improvement / cost of anything you can do to your speakers. You would mount the pair at the bottom / back of the cabinet, right through the MDF panel (bottom or back). You can gain sufficient access through the woofer and the existing input panel.
Let us hear about your outcome.
