Looking for input on Legacy Audio speakers purchase.

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!

Thanks All!

If you have the budget, go with the Aeris with Wavelet. Aeris is an open baffle design vs Focus closed box. A very different beast. I would go with the Aeris any day.

I have the Signature SE now as the Aeris is just too big for my room (not the sound, but the size) and wife has issues with it. I have heard Legacy speakers in many different occasions, in shows, in private homes and in their Hollywood showroom. Tremendous value for your money. The Whispers are the most natural sounding speakers I have ever heard, regardless of price (some well into 6 figures).
