I am setting up a stereo + receiver system at home. With $4k budget, i might be getting the stereo part up first. Currently looking at Sonus Faber Concertino Domus or ProAc Reference 8 speakers to match with Rotel 06 Series player and amp (RCD06 cdp, RC06 pre, RB power amp).

The problem is, I can listen to ProAc and Rotel in the same shop but not the SF with Rotel. Anyone has any experience in matching Rotel with SF?

I also heard the SF are slow and warm speaker and are intended more for movies. Is this true?

What are the things to look out for when matching amp with speaker? Is it amp output power? speaker input impedance? crossover? etc?
