Hello lak, Yes i agree with you. The more MC O5s at the wall plug the better and i would start at the plug that feeds your amp. Then your front end equipment. Filling the open plugs on your MC 6 does not hurt. I saw High Fidelity do a demo with them adding the MC O5s to the open sockets and it all so made a difference for the better. But for me at the wall plug first was best.
