I've heard the Aerials, N805 and both SF speakers (I own the SF Concerto). I don't like Aerials in general though many others love them. I like the 805s. Paired with a Krell amp I thought the sound was terrific, very full from top to bottom. I bought the Concerto over the Grand Piano with the intent of adding a Rel sub, which I believe is needed since the Concerto only goes down to 45hz (last years model) or 40hz (this years model). To me the, the Concerto sounded a bit more musical and open compared to the Grand Piano. Adding a good sub will cost between 1K and 2K so the overall cost will be slightly more than the GPs. I should add that I have not heard the new model of the GPs.
If you buy the speakers used, you should be able to get the Concertos for approx. $1,100-1,300 and a good sub for 1K.
Good Luck.
