Genesis APM-1 or Thiel CS-7 speakers

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.

I owned the Thiel CS 7's but sold them as my listening room was to small ( low ceilings). I listened to the Genesis Amp 1 at Soundex and they sounded more like H/T. I was disappointed as I own a Genesis 900 subwoofer and thought the rest of there line would sound as good. i am not saying that there other speakers are not good but IMHO the Thiel 7's are alot better. Plus you can always upgrade to the 7.2's later. But it's all in your ear. Good Luck!

Thank You for all the info from everyone that replied and I will try to listen to both speakers with my amp then make a judgment.

neither speaker will exhibit its full potential with the mit's in your system. IMO, you're gonna need more neutral wires.
