Martins kits are lifesavers for B&O equipment, get them and try one speaker first to hear the difference, I hope that RL 35s are not your only B&O pieces, tell us a little more about it, and go to your profile and tell us which part of the world you occupie, then its easier for us to give "lokal" advise and help.
