Spendors are ridiculously good speakers I am told.
Thanks for touching on the Corner Tunes - I've been dying to know what you think about them. When you test out the Corner Tunes go ahead and set everything else up and get used to the sound for a few days (or a week) and THEN install them. You should hear the timing of the music change drastically - and of course a reduction in harshness (midrange echoes.)
Happy Holidays to you and yours'!
