Genesis APM-1 or Thiel CS-7 speakers

Don, while I can not attest for the Genesis speakers, I have a set of the Theils and enjoy them thoroughly. They are very neutral and have a superb sound stage. I am sure that the Genesis APM-1's are fine speakers also. Let your ears make the decision. All I can do is assure you, if you choose the Theils, you will be purchasing a fine speaker (In my humble opinion) manufactured by a reputable company that will provide you with alot of listening enjoyment. Good luck in your pursuit.

I own Thiel 3.6s, not even in the same leage as the big 7s but I'd caution you about using a McCormack amp with Thiels. They are current limiting and might make the Thiels sould very bright. Compare the impedence curves of the two speakers. Thiels generally dip to about 3.6 ohms and unless your amp can deliver exactly twice the power at 4 ohms rating as it does at 8 ohms you are likely to be unhappy. If you are looking for a tie breaker between speakers this might be it. I love my Thiels but these $4600 (new) speakers and being driven by a Krell KSA200s ($8500 new) amp.

I own the Thiel CS7.2s, but I am not familiar with the Genesis APM-1. No speaker is pefect, but the big Thiels do many things RIGHT IMHO. It is an accurate and neutral speaker, has great purity of tone, and is superbly integrated. I'm sure the McCormack DNA-2 can drive the CS7.2s (it should at least double its power into 4ohms), but the Thiel CS7 is even a more difficult impedance load. You should listen to both the Thiel and Genesis speakers with your amp if possible. I drive my CS7.2s with Bryston 7BST monos in parallel mode, but have shut down lesser amps that are not high current designs.
