Ewha,
You are looking in the right direction with the Triangle and Totem lines. Great stuff. The Sonus Faber has great midrange, but I found them to wimp out on a bass foundation and I'm not a bass freak, I just would like some.
I've fallen in love with these Coincident Mini Triumphs in a secondary system and can only imagine what the Triumphs sound like. They would fit into your price range used. Check out their website and reviews at

The Spendors are great too, but I would look at ATC, another British manufacturer first as they are a bit livelier than the Spendor.
