jon, there isn't much knowledge or experience yet with the EP500. However, let's think about Axiom making this claim. They are the experts and would be in a position to know how the SVS compares. They also do a pretty good job with audio, as we know. Here is the biggie - I have NEVER seen or heard any criticism of their advice or it's veracity and they never oversell or overcommit. Finally, they have a 30 day return policy. If I was in the market and was going to spend the dollars at this level, I'd certainly give the EP500 a try based on their recommendation. Just my $.02.
