I'd use the KSA-150 first! Detail and Imaging were excellent when I had it paired up with Snell C-IV's a few years ago. Bottom end control is awesome and very well defined. Snell's can get a little loose down low and the Krell brought it right into focus. Your CJ pre should soften up the upper octaves with the Snell's......Best of all the Resale on a KSA-150 should be better than the Aragon 8008BB if you don't like the match...(In fact let me know if you don't buy the Krell and how much they want for it. That's how much I like mine, I'll add a second one to the mix!)
