Tannoy vs. ATC

I'm looking at ATC SCM40 vs. Tannoy Kensington. Two very different speakers, I know. No.1, I need a speaker that can be placed close to the wall (less than 3 feet). I think both apply there (I didn't say it was ideal). Among other things, I like the Tannoy because I have a 40 w/ch tube amp, and the Tannoy is more "child friendly" (as far as tipping over and access to delicate drivers). The amps also have sentimental value and I would like to use them. If I buy the ATC I have to get other amplification, which I am willing to do because I love what they do (leave the child friendly part to me on this one...!). So, with the 40w/ch tube amp and the Tannoy (which may still require more power), or the ATC with 'competent' SS amplification (TBD), any recommendations on the two? Amps are vintage (and fully functional/restored) McIntosh, currently running Klipsch Chorus speakers (my temporary compromise to allow for Children...hard to push over or destroy!..which actually sound pretty good by the way, just not much in the way of imaging or accurate bass). I have NEVER heard Tannoy Prestige series, but I am going out on a limb based on all the web and print-based anecdotal evidence. Third choice - hold out for Canterbury? Also a factor in the decision, eventually I will be able to use more of the room for placement. My room is 20 x 13 feet. As far as preferences, I like heavy classical music, as well as softer music - classical guitar, choral, etc. (and listenability at low volume is important too). I have found that I do prefer accurate loudspeakers in general, and accurate bass is very important to me (organ music is a staple). I am willing to use a subwoofer. I'm hoping someone might have experience with a lot of this gear. Thanks.
