Legacy Focus SE or Magico A3

Neither. Get the new Revel F228Be. Same price ~ $10K

+Joseph Audio, go listen to your music run thru a dac, spend some coin on room treatment (if you haven't) and cable it up right.  
Enjoy!

@jafant It is an very well designed & immaculately built amp with plenty of power on tap. Though personally I think the Audio Analogue Maestro Anniversary is the better looker and equally nicely put together.

I haven't listened to the FLS-10 in my system, though I got to hear it recently in my friend's system. I've also heard the flagship Strumento amps in a familiar room which sound great at their respective price points. The FLS-10 gives you a taste of the Strumento's sound at a fraction of the price, and is has enough power to drive all but the most demanding load (eg: Magico Q5, Apogee Scintilla 1 ohm). The FLS-10 sounds a bit like the Classe CA-2200 (ie: clean, smooth, detailed), but also has a bit of the warmth, richness and flow of the Strumento amps. If you need a lot of power, it is an easy recommendation.

I'll add one more vote for Legacy Audio, particularly since you're so close to Springfield. I was there a couple of months ago and Bill had several extremely nice sets of Focus' available, and seems to regularly have a good selection from trade-ins. Most importantly he makes sure they are working "like new" and stands behind used ones like they're new. SO much better than other used options, even from good dealers.
