John, since my experience with the Pioneer vs Denon, I wonder if your bass problem isnt related to your electronics.
SRP, reading your posts and understanding more about you and your layout, I highly recommend staying far away from any Axiom v4. I lived with v2 for 11 years and since I've switched, I can't pull away from it. I've become consumed by it. You will find yourself listening more and more until you just lay there like a lump, wasting away in audio nirvana until your loved ones place you in an asylum.
You will kick yourself for not upgrading earlier. And you will love them so much, you'll want to feed them the best signal possible.
