I just traded an LP12 in for a RP10 and had severe FF issues with my floor.
I had two Lally columns in my basement supporting three joists to eliminate
the flex in the floor. I also had a brace between the wall and the top of my
cabinet to eliminate any rocking movement at the top of the cabinet. If I
didn't step softly I could still force a skip. With the same cabinet and all
bracing removed, I have yet to have the RP10 skip.
My suggestion is get the table and see how it reacts first. Then I would look
at a wall shelf before I would ever brace the floor again. Soil can expand
and that expansion could cause the jacks/supports to force the floor joists
up and possibly do drywall damage or damage to the floor joists. That was
one of my primary reasons for trading off the suspended table, I had
noticed movement in the structure of the house that concerned me, e.g. a
door a few feet away not closing. I love the RP10 but have to admit now
after a time that the LP12 had a better sound that I miss. But it is close
enough and eliminates the structural concerns of a larger investment.
That said the shelf makes much more sense in the long term picture. Or at
least that is my opinion.
