Hi randy,were always nice

I Think pengs advice was spot on,from the gear you listed i think you'd notice a more dramatic improvement by upgrading your main speakers,dont think im bashing your klipsch gear because im not,its good stuff & i own some klipsch gear but pumping cash into electronics with the speakers you have is a lateral move.
If you decide to go with seperates buying new gear from a dealer/manufacturer offers very little value(huge mark up's)weather you buy from a web dealer,manufacturer direct or a brick & mortar dealer you will be paying a premium,you'd be much better off going to dealers stores & auditioning everything you can to get a feel for what brands & models you like then searching the site in the link for that model or a like model that will meet your needs.
If you dont like shipping used gear you can use the zip code feature on the search function to buy gear in your area.

Im a firm believer in running seperates in all cases but i also believe in running seperates that will stand the test of time & hold resale value,buying cheap seperates will get you the latest & greatest connections but offers very little in resale value,last years models can be bought used from audio & videophiles who take great care of their gear at huge discounts,do some research over at audiogon on used seperates from krell & mcintosh,these brands offer a greater resale value than any other brands & for the features you want are within your budget if you buy used.
