Hi all, just picked this up saturday and love it!!! What a beast.....some quick stupid questions however as I'm not upgrading to 6.1 or 7.1 for awhile: a) What's the best sound mode to use for a 5.1 setup? Neo, THX, Dolby ProIIx and the other ones seem best for 6.1 or 7.1...or am i just confused? right now, the modes i'm running are Advanced Movie, Advanced Music, Game, etc. b)should i leave the crossover setting at 80hz? c)also, while i'm on the subject - floorstanding speakers as rears?? anyone do this? disadvantages if any? here's my speaker setup: klipsch kg4.2 up front klipsch kv3 center two cheapy surrounds (might get the klipsch sf-2 from vanns - on sale for $400/pair!!) JBL dual 6" subwoofer thanks all in advance for your info!!
