probably...The 7 feet allow for leveling, all the other models use washers, which would be not fine enough adjustment.
I have yet to jump on the isolation bandwagon [ REO ] .... and I think it took Helmut Brinkman with his own personal model 7 w Brinkmann Gfanite isolation system to gain a concensus that it yielded better overall sound...in the Munich demo room... [ hope to attend next year ! ].....a matter of priority I guess, other things in my system I would like address first....
I know Mapleshade consider solid Maple superior to glued up laminate but I had some leftover almost 2” think laminate left from a kitchen remodel..I made them into amp stands w Model 5 cones, I did use a T nut from the top also. You could probably build a set of Maple w 7 cones and get a stand that you can level fairly inexpensively.....Remember parts thru your local dealer, service via factory. BTW for my MC240, sonics worth it. The MC250 didn’t care...ha
my amp stands in WA, TREO in CA, otherwise I would give it a listenten and let ya know...
have fun
