speaker guidance for R&R mostly

Hey, Thank you. Had an old pair of maggies YEARS ago and really liked them. Didn't even have a sub then. I believe the model was MG 2A or something similar. Listening to pink Floyd (money) was so accurate and impressive. Hadn't really thought about them. Thanks, may open that door again.

I forgot to mention, relative to above, would like to stay around 10k to 12k used if it would buy me more speaker. Flexible somewhat. 

to  mofojo and soix: Thank you both for your posts: I really do like my tektons a lot, my wife thinks I'm nuts! She's probably right. To Soix: Thank you, I have viewed these from time to time. I have seen-used for this price on Audiogon or music room, but, just looked as I still owe on the Pass Amp. I am very tempted,especially due to the Price.  My only concern, probably stupid, is with the Tektons being as efficient as they are,  I always run, no matter how loud in Class A power. As the ATC is much less efficient, just wondering if i'll remain in Class A or go into AB and which is better? Tektons in A or ATC in A or possibly AB? Thanks to both of you. Much appreciated.

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.

Thanks all for the updates. I would have to go back and look at the review dates for the ATC's, to see if maybe the older tweeter for review or the newer was used? Thanks, didn't even think about that. Also read and reviewed several articles on the super tweeter, Townsend model. Didn't even know about them, learn something everyday. Have always liked the look of the SCM -40's now more reasonable;e than before. TOO many choices! Thanks

Yesterday listened in my main area  for 2 hours ,which contains the electronics I mentioned in my earlier post.    I will never sell my upgraded Tekton DI's, Listening to Led Zeppelin, RUSH, Def Leopard,etc, Just WOW   Everything was just PERFECT.  However, I am still very Interested in the ATC 40, especcially at the now lower price. May be my XMAS present to myself.  

     Thanks to all with your thoughts, especially about the ATC and the Super tweeter, very interesting.  Again thanks!!!
