Only after 5-6 weeks of setting up my first 5.1 system, I am already getting VERY curious about 6.1 and 7.1 surrounds. Heh-heh... So, how much of a difference will the 6.1/7.1 make, if I do NOT have any natively 6.1- or 7.1-encoded materials? Does it worth an additional Axiom or two, for just doing matrix decoding?

(FYI, I do not plan to buy an SACD/DVD-A player just yet, until the dust settles a bit more with regard to bass management and other technical details, until I see that they are definitely going to survive as media standards for long-term, and until truly interesting classical music recordings start to appear on them.)
