yes, I not sure yet either.
I just need get my speakers bought over the next two years of what I want.
I have M80's now in Ver.3 and was going to go with Ver. 4 but now that Axiom has priced itself with the competition I am curious to see what maybe better at the same price.
Use to be there was a difference I could get a $1500 set of Axioms that performed as well as a $3000 pair of speakers. Now it's $2800 M80 HP which is just as equivalent as Paradigms Studio's 100 or Song Bird's or Totems. Just wondering if for a 7.2 system and you had $12K you want to spend what would you buy. could even consider +- $1000 if needed to get that good second sub.
I currently have a Anthem MCA50 and a MCA20. I have a Anthem AVM309 Which probably be upgraded to a AVM60 or D2v( or whatever the newer version will be in a few years.
