speaker guidance for R&R mostly

You have a very Valid point. Thank you, I did a lot of reading and investigating yesterday on the ATC scm-40. The New price used to be around 8K, and your post shows $5999, a nice price drop for new. As I read further, several of the articles really were impressed with the BASS and The Mid-range sound and drivers. However, Every article and reviewer claimed the High Frequency driver was OK, mediocre,  at best and needed an upgrade,  and most alluded to the price drop as the result. I don't know yet if the SCM 50 has a similar issue or has a much better tweeter. Of course it's much more expensive. I'll keep you posted. Just for your info, I'm much more interested in Mid-range and hi-frequency performance as my SVS sealed 4000 sub does a GREAT job on the low end. Thanks again.

I'd give Volti Rival a consideration. You are close (ish). Greg Roberts I'm sure would be happy to have you come for a listen. 

I had a pair of ATC SCM 40s and loved them but I used to be concerned with the tweeter until I had a demonstration of the Townsend Super Tweeters , job solved. People will argue the they make no difference ( that's because they can't hear more than 14Khrz themselves. I found also that the bass got more detailed because of the extra harmonics added to the music. Yes I cannot recommend the ATC's enough !!!

Be mindful that ATC did a serious upgrade of the tweeter several years ago that, from the reviews I read, was a significant improvement. If you’re reading reviews of models with the old tweeter you’re not getting an accurate assessment of how the speaker sounds now. This will obviously also be highly dependent on the electronics preceding the speakers, especially with very neutral speakers like the SCM40s, and with the refinement of your amp I’d tend to doubt you’d have an issue with the tweeter. That said, I’d also mention that both Music Direct and Sound Approach offer free shipping and a return policy where if you just don’t like the sound of something you can return it. You’ll be responsible for return shipping, but it’s still nice to have the option. Last, I highly doubt a tweeter results in a $2k price drop and think there’s gotta be something else at work there, but what do I know? FWIW
