avr receiver help

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

"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..."

Harmon Kardon AVR354 will fit that description, sonically, for new. Plus you'll have the newest codec's (don't know why you'd settle for inferior resolution, otherwise). Used, most any Denon - the better ones obviously more expensive on used market. So shop around. Also, yes, the Arcam used is superb sounding, but no new codes, HDMI, and no EQ (I think).

"i was thinking to go seperates but do not want to go overboard".

You do have $8k speakers, why would you have $8k speakers and drive em with cheaper electronics?
Overboard? You can easily put together a budget separates system for maximum sound in that budget. You could do a moded HK AVR354, and have money left over for a good outboard amp from Rotel,Parasound,Adcom, etc, that will improve sound, no doubt!
good luck

The Onkyo 805 was $599 yesterday at Amazon. That's a seriously good deal. The 805 is a powerhouse and has great features and connectivity.

Arcam AVR 350
a few listed here on audiogon

no hdmi, but the analog outs sound clearly superior
