ML Aerius or SL3's?

SL3 no question about.

I have the SL3's and bought them at the time because the larger stat gave more of the ML sound, and I like the better bass extension. I agree that it is, all other things being equal, superior. However, if you have a small space and value cohesion between the stat and woofer, then the Aerius is worth considering. Either will sound good with okay electronics, and great with great electronics. Whichever you get, drive it with the best you can and you will be well rewarded. I just came back from CES and many of the systems on display there couldn't hold a candle to my humble setup. (of course, there were more than a handful that really were very special, too!)

I owned SL3's for nine years....tube amplification won't cut it...you need a ss high current amp with at least 200 watts at four ohms and 400 at 2 ohms...these are power hungry designs.

SL3 no questions about this!! I own a pair of SL3 for almost 9 years and I still don't have an upgrade itch yet without paying big bucks for replacement such as B&W 801D, Wilson Watt, Sound Labs M1 and etc. I use AR VT100 MK3 to drive them and am very satisfied with the sound. Go with SL3 and you won't regret it. The only problem is that the panel will sag and you need to install a stopper to keep the panels up (check out the ML user web site and there are solutions to address this problem).
