Wow, that was fast, Chesseroo. I wasn't expecting a reply for a few days at least. LOL!

I'm not definite on upgrading as I don't know the relative benefits of the V4, nor the technical improvements that have been made over the years. All I know is that my Axiom setup (with an SVS PB-2 sub) blows away friends' HT rigs that cost more than twice what I paid. cool

I guess I may have to call Axiom and see what they say. I'm sure they still have my invoice on file somewhere...heck, my account on these forums was still good and I've not posted in a very long time.
