@Stover, @TOBYJUG - this was what I had believed as well and was under the impression that the Sopra 2s would be considered a much better speaker and honestly thought would hear that the ATC SCM50s would make a better comparison rather than the SCM 40s.
As I mentioned, I have heard the Focal Kanta 2s and really liked them and from what I’ve gathered the Sopra 2s are all that the Kantas are and more (perhaps not too dissimilar to how an ATC SCM50 is better than an SCM40?). To me the comparison was of a much more expensive (and hence possibly better) speaker that was only under consideration because of the much lower used price available. I was a bit surprised to find so little love for the Sopra 2s here.
However, I do get the point on how critical it is to audition before buying and have pretty much decided against the Sopra now unless I can manage to listen to them somewhere before buying. Also, my poor Atom seems to have become collateral damage in this speaker comparison with almost unilateral advice that it’s the weakest link I know I need to move up on the source but was really looking to buy a pair of speakers first.
Thank you all again for your inputs, I really appreciate you’ll taking the trouble to assist. This is really a great forum
