I have the chance to upgrade my speakers. My current set up is simply an Audiolab 8200CD going into a Rotel RA1520 amp and out through KEF Q300's. I like the sound and it fits my room, but feel the speakers are at a lower level than the other parts of the system. I have the chance to acquire some cheap KEF XQ30's which I think would be an even better fit and would improve the overall sound. Any thoughts on this ? Thanks
