I recently got a yamaha reciever from Crutchfield on a 30 day try out. When I went to try pro logic 2 i was disappointed to see that it only worked on Dolby surround sources only and not on mono movies (I have several mono only movies on various formats DVD,LD,Vhs). Anyway I was looking on around and found there is a sound mode called Circle Surround 2 that has a mono mode. I know of only 2 receivers that have it Kenwood and Marantz. I have heard both have had quality problems in the past. Marantz I can only get from accessories4less which sells refurbished units which I am a bit leery of. I was looking at the 5300, but I read on another forum that bass management only goes down to 100kHz as opposed to the yamaha's 90kHz. I would have to get the 7300 for it to go lower which is out of my price range. The Kenwood seems iffy to me. i kinda regret upgrading right now. I did have a 4 year old denon (which bass management went down to 80kHz, i sorta miss that low end bass.) anyway I have a couple more weeks of my 30 day try out and at a loss of what to do. The Yamaha's built like a tank and packs a great punch, I just wish it had CS and better bass management. Any advice?
