What was the first question?
Sounds like a decent setup. Does the system sound good? What did you expect to not "match" with components intended to mix and match, tho? Only thing I can see from a glance at spec is that perhaps the Rotel receiver isn't rated for 4 ohm for your speakers, but is likely adequate (altho perhaps not at high volume levels....). Might not be the best setup for a digital source but for analog looks fine.....and you can always add an outboard DAC for that.
