Ok, I haven't bought yet but I'm planning to have 2 front Polk Audio RTi8 towers, CSi3 centre speaker, and 2 polk fxi3 surround(rear) speakers. im planning to upgrade to 6.1 in future so the receiver has to support 6.1 and have enough power,etc(other factors) that will make it play well. and i havent picked a sub yet but just pretend there is a 10" sub. so what receiver around 250-350USD price is good for this system? Would the Harman Kardon AVR235 Dolby Digital Receiver be sufficient for this system? How about the Yamaha HTR5750S Dolby Digital Receiver Yamaha HTR5750S Dolby Digital Receiver? I know Denon's and Harman Kardon's are good, but they are just too expensive new, for me at least. Yamaha looks good but I heard they exaggerate on specs, ie wattage per speaker, but you can take that into account. If you have any other good receiver's that are worth pointing out for a good price, let me know. And if you want to sell one personally, you can let me know as well I'm from Canada.
