Hi I have pretty much the same setup. Myryad MDP500 G6 preamp MA500 power and teh MCD600 CD player. I tried loads odf speakers and I can tell you that the speaker you want is the Proac D15 floorstander.
I know you posted this like 9 months ago but if you are still not happy with whatever you've go then get the Proacs.
