Ok, I'm new to this and am trying to start expanding my home theater. I currently run a Sony HTIB that I got from Circuit City for $300 with a receiver, 5.1 speakers, and a dvd player. But I only use the front channel speakers, cause I don't have room for surround anymore. Also, the speakers suck, so I'm upgrading now that I have the cash. I like the Klipsch sound and am probably going the Forte/Quartet route.
Anyhow, I get confused as to what kind of electronics I will need to upgrade to complete this system. I read all this stuff about amps and preamps, which I thought was all included in a receiver, but I'm not sure. So basically... if you wanted to run a 2 channel home theater with some vintage Klipsch, what electronics would you get? I will need HDMI and digital audio inputs, and am thinking I might want to futureproof and get a 5.1 receiver. Do 2 channel receivers outperform 5.1 receivers set to 2 channel? Mostly I care about musical performance, but I don't have the space/cash for a 2 channel audio system and a home theater, so it needs to all go together. Advice?
