First of all, this is a great site. I am really a beginner in all of this. I need a receiver for this setup. I am looking at $400-$500. Speakers I just got.. Infinity Aplha 40's for R/L Infinity c25 center Ininity ps8 sub Infinity ers210 in-wall for surrounds. Looking at Yamaha v640 Denon 1804 Onkyo 601 Marantz 5400 HK 230 HK 325 refurb. Any info would be great. I am only able to listen to the denon and yamaha. I am not looking for the perfect receiver, just do not want to make a muistake, if I have to order on-line. thanks in advance.
