I love the 4 M80ti speakers in my 5.1 system. I use it mostly for listening to music. I have a small selection of SACDs and DVD-Audio disks. The 4 M80ti's and the VP150 are perfectly matched. The Denon 3805 does a very good job of converting regular 2-channel stereo CDs into 5.1 channel audio. So again, the five speakers form a beautiful sound machine! The EP600 is icing on the cake! :-)
For movies with Dolby Digital 5.1 or DTS 5.1 sound tracks, the rear M80ti's are overkill. But I compared the cost of two QS8's ($500) plus FMS QS stands ($270), and decided to fork over a small additional amount and get two M80ti's ($1240) instead. I don't have the space right now, but eventually I might get the two QS8's and convert my 5.1 system into a complete 7.1 system. The Denon 3805 I have is a 7.1 channel amplifier. I am going to bi-amp the front two M80ti's. Then I will be using all seven channels on the Denon 3805.
The instructions for bi-amping speakers with the Denon 3805 can be found on this page:
The front two M80ti's will get 240 wpc. But since they are 4-ohm speakers, I guess it will effectively be 480 wpc! The M80ti's are rated for 400 watts, but Jean-Claude (?) at Axiom told me they can easily handle 1000 watts.
I have had the speakers for only two days now. But I am very happy with the sound quality (and the price!). Before I bought the Axioms, I listened to a variety of speakers made by Polk, Martin Logan, B&W, Monitor and Paradigm. I almost bought the Martin Logan Aeon i speakers. I am glad I ended up with the Axiom speakers. I still find it hard to believe that comparable speakers cost 2 to 3 times more than the AXIOMS!
