I own the original Legacy Focus speakers. I have heard that the Focus HD is inferior sounding despite the higher quality drivers. The SE version is very similar other than the placement of the ribbon tweeter. The Focus has 3 woofers as does the Focus 20/20. The Focus 20/20 has a slightly more difficult impedance than the original Focus. Besides sounding better, the original Focus sells for about $2500/pair. It can be driven for rock and heavy metal with a 35 watt Yamaha CR-600 ($150) and sound great.
I mention this speaker not because it’s the best but because it provides me with a balanced sound with great detail like a planar or electrostat, wide soundstage, good imaging (with Shakti Hallographs), plenty of bass, beautiful tonality, quick transients (not as quick as a Magico) and dynamic (not as dynamic as a big horn system). It is revealing of your equipment and tweaks, so there is always an upgrade path to owning them. I used to own electrostats, big ones, for 20 years. Then I found out about the Focuses from my friend Robert Pincus. Steve Hoffman, Tom Port and several other friends own(ed) Focus speakers (the originals). There is a good reason for this and it wasn’t because we couldn’t afford a better speaker. My wife of 20 years thoroughly disliked my electrostats because they lacked dynamics, bass and required center only seating to enjoy them. She likes rock and heavy metal. The Focus and Signature IIIs were a perfect replacement for both her music and my music (opera, jazz, orchestral and earlier pop).
Also, Magico’s are more difficult to drive and you can buy 4 used pairs of Focus speakers for the cost of one Magico pair. I hope this helps.
P.S. Be sure that the Focus mid-range drivers have plenty of dacron or other dampening material behind the drivers; otherwise, they are brash and especially bad on brass instruments. My pair needed a pillowsworth of dacron for the 4 drivers because the prior owner left the chambers bare when he rewired them.
