For my money, putting the MD600 directly on top of the MS600 makes no difference. Placing isonodes underneath both in the same configuration certainly does - more musical sound. And the biggest surprise of all, using Russ Andrews Classic cables for both makes a big difference for the better. I also use isonodes under my 5200s - and yes, they make a difference too. thought I had left all of this messing about behind when I recently bought my system! It now sounds fantastic. smile
