Looking for input on Legacy Audio speakers purchase.

I was thinking that the McIntosh MC611's would be overkill for the Aeris with built in amplification.

@wgapel,

I wasn’t aware they had powered and non powered versions.  I do know the Wavlet was used as the preamp and the speakers had speaker wires attached to them. The sound was so effortless.   I did notice the monoblocks meters would swing up to 600 watts at times. I have a MC302 amp it it is very powerful.  If you think you need less power, perhaps the new MC462 @ 450 watts per channel would be enough for them.  Although, I am a firm believer that you can never have too much power. 

The Aeris have built in amplification for the 12 inch subwoofers. If your room and your budget support it, that is the way to go. If you already have the amps, I wouldn't sweat it about having too much power. The Wavelet is a really nice piece that will allow you to really dial in the Aeris.

Never too much clean power. I'm not joking. I do not care to work with less than 2-300wpc now. I prefer more, as everything changes for the better with increased pure power.  YMMV 

I had an old pair of original Focus speakers and enjoyed them for over 25 years driving them with PS Audio 250 Delta monoblocks. My biggest issues with them were trying to tame the bass (the newer Focus have 2 driven woofers compared to three in the old) and contouring the mid-range as they could be a little harsh at times. Overall though, I thought they were great.Finally upgraded and got the Aeris in December. Tried driving them with a PL EVO 400 amp. You would think with the speakers rated about 92db at 1 w that the PL at 70 wpc would drive the upper end just fine. That was not the case. Although the mids sounded great the upper end sounded rolled off with muted detail. At louder listening levels it was quite apparent that the amp wasn't up to the task.
I purchased a set of Pass Labs x260.8 monoblocks since their A class output was 50 watts and the difference was just amazing. These amps may be overkill but I wouldn't change a thing. I would agree with Douglas and others that having "too much power" is a non-issue as opposed to not enough. 
I would also add that the Wavelet is a capable preamp and DAC. The room correction is the real deal and tamed my difficult room immensely.
One has the capability with the Wavelet to contour the sound to your liking. I found this feature to be a very useful tool especially with some older recordings and also that I like a little more bass presence than the un-adjusted room correction provides. I had considered going with the newer Focus but have no regrets buying the Aeris and am more than happy and satisfied with them. Only thing is though....... I wonder how the V's sound... hmmmm....

Happy listening and good luck on your journey!
