The MLs require lots of power from a heafty amp, one that will drive 1 ohm load that the logans will occassionally present. Also, I have found that, maybe similar to your ears, the logans are "bright" or "transparent". A powerful, "musical" or "warm" amp (as opposed to an analytical one) might give you what you want. Also, the aerius may need a sub for good LF playback, depending on the size of your room. I have quest z's and find myself wanting deeper, more dynamic base. If you find a servo controlled sub with an internal amp, the logans will be freed up to play the mid and highs. Also, judicious use of ASC tube traps is a must for tight, deep base. Hope this helps.
