After reading through the glowing reviews of these speakers, I have been considering checking these out even though I have not heard them. The problem is that I just bought 4 Mini Monitors, a CC-370, and I have 2 Monitor 11's waiting to be picked up by me in Canada. But the store I go to has a really cool policy that within a year of your purchase you can exchange the Paradigm speakers you bought and put the money they cost towards another set of Paradigm speakers. So I'm thinking of jumping to the Reference line. I don't even have my Monitor 11's and I'm already thinking about upgrading, you bastards! My questions are these: What would be a comparable set up to what I just bought and how much would it cost? I want tower speakers for the mains, I don't like to use a sub when listening to music. I have heard you need a lot of power to run these speakers, especially the Studio 100s. I have a crap receiver, a Sony STR-DE725 receiver, and when I upgrade my receiver later on, at best it will be an Onkyo 898. Will these speakers be wasted on me because of my cheap receiver? Will even the Onkyo 898 do them justice? What's the difference in the sound? I know that's tough to describe. Would this upgrade be worth it? Do they come in black? Thanks! James ps some prices in Canadaian funds would be nice so I could see how much I would be paying in US funds.
