I'm looking for a new receiver and see that Circuit City has the Onkyo on sale online for $720; Best Buy has the 5590 on sale for $664. Seems like Onkyo has generally received better reviews here and elsewhere recently, but I'm wondering how members here feel about how these two particular models stack up against each other. Which should I get? Please keep in mind that I'm limited to either Best Buy or Circuit City per the wife's orders (store credit cards with room to charge). Thanks for any input!
