you do not list any other restrictions, whether size, color, usage, # of speakers. Assuming strict budget, my vote is:
6x PSB B25 $900 total
Onkyo 805 refurbished $600
Save $500-600 for another day for a sub, either SVS 12" or AV123 MFW-15.
That Integra could be a good deal, but I needed to shave off $200 to get some nice 6.0 speakers.
I personally don't think my combo can be beat for the money for HT usage. If you had 2k, then add sub. I could have gone eD for sub, but I spared you the ugliness.
the center channel would be an upright bookshelf. gives you superior performance while costing less than a "center channel speaker" due to its inferior compromised horizontal mtm design.
If you have more money, you might try Denon for the receiver if you worry about Onkyo QC. But a similar model seems to cost about 3x as much.
I've been looking at a couple different options:
Best Buy's Mirage Nanosat 5.1 system and a Denon 1508 receiver for about $1000.
Paradigm Cinema 90 CT system with an Integra 5.8 receiver for about $1300.
Is there anywhere else I should be looking? Other brands to check out? What's the best bang for the buck?
