You can get better only if you spend a lot more. Soundlabs A1,M1 etc are great speakers as are innersound electrostats and apogee duetta signatures. A few changes in amp/preamp, and crossover components might be worth more than "upgrading" to a different speaker. Try using a high current SS amp with a tube pre amp. Then consider upgrading the on board crossover.
Anything better than Magnepan 1.6?
So, its been out for something like 9 years, but it still seems to be absolute top of the line. I also see the Dali Ikon 6 which seems to have amazing pinpoint staging accuracy. The same recording of a female Jazz singer has a mouht the size of a woman on the Ikon 6 and maybe 5 feet wide, maybe 4, on the Magnepan. Which is a positive thing for much music, that 'wall of sound' thing they do. And it has a much, much better sense of 'air' with the combo ribbon tweeter and dome than most box speakers.
Anything else I should consider? Even up to 3k? In that range, after having Maggies since 1988, speakers like the appropriate B&W and similar don't seem to compare in my opinion at all - I guess its a planar thing. The sound is so obviously coming from a little box! Just can't do it. I love Thiel in general, but in this price range I don't get enough volume.
What about Innersound Isis? I might be able to get a used pair? Tight sweetspot annoying to me, I often have people over to listen to music with me.
Oh - and I don't care about Bass below 80 Hz and possibly a bit higher, but 120, absolute top of 160 might be okay if everything else is outstanding. I already have a VTF-3 HO Hsu subwoofer with turbo.
I listen to almost everything, so that is of no help. If I had to chosoe one to focus on, I'd choose classical, but I listen to a lot of Shostakovitch for example, which is basically heavy metal in classical, so an accurate speaker that doesn't punch you a little won't work.
