I'm a Sonata fan, I have the 2's and would like to move up to the 3's when I can swing it. I know what the 2's do well (am very happy w/ mine) and Jimman sounds spot on in his description of the 3's. I can't say I've ever heard the Legacy's but I was under the impression based only on hear-say, that they were a bit less refined speaker, more in the gene pool of the original rock and roll breed, perhaps akin to the old Altec Lansing flavor... play loud, play hard sort of thing? ("not that there's anything wrong with that" as I'll always have a soft spot in my heart for speakers that can really rock). The Silverlines will probably be a better match to your electronics though... I owned a Counterpoint SA-100 back in the days of Corey Greenberg at Stereophile... it was a really nice amp, not only in its day, but I recommended it to a friend of mine who's been very happy with his for the past 15 years. But what I'm really jealous of is that SA-11 of yours... wow, how cool is that. I think the tubes in the 11 and the hybrid 100 will gel with the Sonata sound. I've owned the SA-1000, moved up to the 3000, and finally owned the SA-5000 for many years (always dreaming of the 11) and I'm sure Michael Elliot's magic touch on your upgraded 100 will be well expressed through the Sonatas.(IMHO). BTW, I still use an upgraded Counterpoint DA-11/DA-10 transport/processor combo for my digital source.Good luck and I hope this helps, Happy Lissn'n
