avr receiver help

i placed my speakers about 2 ft out in front of the ht or closer towards the listening position, the speakers look like an eye soar as they stick out further into the room but it is worth the improvement in the soundstage, i also moved the center channel speaker 2 ft out in front of the ht and what an improvement, the speakers are just about 6 ft from the back wall i tried many different positions and they seem to sound their best in those positions, maybe i should be looking for something with better processers like you said and down the road add some decent amplifiers.

i have the infinity ren 90's set up for two channel listening in a different room, but i also wanted to listen to the mts preludes in two channel from time to time and i was also thinking that they would sound better with a more relaxed,warmth sounding av receiver but i don't know much about each receivers sound qualitys
i was thinking to go seperates but do not want to go overboard as i did with the ren 90's system, i really just want to get a good recever that will complement the preludes. all your help is greatly appreciated.
thanks
greg

i forgot to mention that i do have the subs that go with the mts towers and i probably don't need all the latest codec's.
thanks

in response to the last two posts, i saw those adds but i got to make up my mind on what brand receiver is going to work best with my infinity speakers, i do not know about the new onkyos but my brother has about a five year old onkyo 500 something in the mid price range running infinity overture 3's and he told me that it does not pick up fm signals all that well, is that a problem with the newer onkyos.
greg

the only reason that i asked about the fm section on the onkyo is because i listen to fm alot, on my other system with seperates i'm using a sony st-s730es tuner and it is amazing it comes in crystal clear and there is no need for an hd tuner or a squeezbox.

so far i tried a pioneer, h/k and a onkyo in two channel and i think the h/k sounds best so far with the preludes, the reason for my original post was to get an idea of what brands of receivers other prelude owners thought sounded the best with this speaker so that i would have a starting point of wich receivers to listen to, but you are right i'm going to have to go try a few more of them before i find the one that i like, the two channel pre with pass through sounds like a good idea, thanks for all the info.
