Just a quick post, hooked up the 8033 last night and gave it a listen today at normal volume. Liked what I heard. Will need to experiment more on the weekend. Watching The Dark Knight Rises, the bass is reined in, yet solid and forceful. The subsonic filters are engaged, which is good, because my budget subs don't go that low (and I dont what the Anti-Mode to try). Much better result than using SMS-1. With SMS-1, the bass seemed dead. (Again, no doubt due to my inexperience with EQs). One thing I will say, I won't listen to system without sub EQ anymore.
