Hmm is the Onkyo HT-S7400 5.1 really going to outperform the Onkyo-HT-S5400-7-1-Channel-Theater-System? They are about the same price... *and just noticed the S7400 you linked is refurbished...
And it doesnt sound like you guys are too impressed with that Polk-Audio-RM705-Theater-System? Compared to those onkyos at least?
What did you have in mind?
Yes the 7400 is better, it is actually a 509 receiver that is 7.1 you just dont get the extra 2 $20 speakers, I am not a fan of 7.1, it is hardley supported, confuses the surround sound situation, doesnt work in many rooms {you need a few feet behind your seating which most rooms dont have since couches go against walls. and 5.1 sounds better to me...
The real steal is the 7409 refurbed for $400 that comes with a 609 receiver... If you can stretch your budget thats the way to go for htib...
Also the 7400 and 7409 come with a better sub, my son has that sub in his room on his ps3 and its decent for what it is...
And dont be scared of refurbed, you still get warranty, and I havent heard of any problems, my sons refurbed system was brand new never opened overstock, which is usually the case...
If you want to wait and start a nice system start by buying a nice receiver with preouts so you can add amps later if you wanted, and a set of bookshelf speakers that you can use as rear later when you get better fronts... I know a few people that built sytems that way, start with a $200 set of speakers and a $400 receiver, then add a nice front stage {the FR, C, FL} for $6 to 700, then a nice sub for $3 to 500, then an amp for your front stage for $3 to 700 before you know it you have a decent entry audiophile system that will smoke any HTIB on the market...
