Opinions on ACI Sapphire XL

In my quest for quality bookshelf speakers, I came across the ACI Sapphire XL monitors. I've read many reviews, both professional, and consumer, and have rarely found any knocks on them at all. So, I thought I'd throw the question out here to see what people think.

I have a small listening area 13'x13', and am running solid state gear, an integrated, and Onix XCD-88. I seem to like accuracte reproduction, especially in the midrange, and like to have a decent amount of bass (if possible). My musical tastes run from rock to pop to vocals to jazz to country, in other words, quite varied. If what all the reviews say is true, I sure wouldnt mind picking up a pair used, but they dont seem to come up very often do they?
