Ok i have done quite a bit of searching and I need help on deciding which reciever to choose in my quest to start a home theater. I have narrowed down the options to many actually ,and I need your advice on what to choose. So far I have picked out H/K AVR230, Onkyo SR-502, Onkyo SR-601, Yamaha Rx-v450, (possibly) Yamaha Rx-v650, Denon 1804, and Denon 1604. I know some of these seem redundant but I am still deciding on how much I would like to spend. Also I have just found that Pioneer makes a 7.1 and 6.1 recievers with preamp outputs to each channel recievers for around $300 I think the model numebrs are vsx-ds11s & d912k. This seems like a really good deal too considering the options and the price. Some things of concern or that I want to point out are the "Problems" which some people say H/K has. I would be buying it online and I am kind of weary about buying a product that alot of people have said is problematic. How much of a problem are they? Also the Yamaha rx-vr650, H/K AVR230, and both pioneers are pre/pro( I think thats right?).
