I am looking to upgrade my centre speaker (Paradigm CC350). My front speakers are KEF Q35.2 and my rears are recently purchased Kef Q2ds. My amp is a Sony 1080 STRDB. I was thinking of a KEF 100c (second hand) or a KEF Q9c. If i was to go for the 100c would my amp drive it, as it has a load of 6ohms? Would either centre be much better than the Paradigm, great bass but a bit muffled sounding to my ears.
