I currently have a set of kef kht 1005 speakers with sub, powered by a pio ax3. I would like to upgrade my speakers and was thinking of replacing the front l & r with kef q3's. Would my current surrounds, centre and sub sound o.k with these? Or should i replace the centre as well? Budget is an issue here and although i would like to replace my centre at some point, hopefully with a kef q series speaker,but i would prefer not to have to do it right now. Any help most welcome.
