Chris,
I owned Spendor SP100s for over 6 years, and I now own Spendor 9/1 (same drivers, different cabinet). I urge you to find a place where you can audition Harbeth Monitor 40s. I wish that I had never heard them, because they are so good, they spoiled me for other speakers including my own. I look forward to the day when I can afford a pair- new or used. I have read great things about the new version, the 40.1, but the old version is so amazingly good, that it is hard for me to imagine what there was to improve. Another advantage is that the size and shape of them will be familiar to you, and they will work in your room if the SP100S did.
