At the moment I have Proac D15 as front left and right, and the Cyrus centre speaker. I'm considering my next step, which I think will be to buy the Proac sub ER1. I can also buy a new pair of Tablette Reference speakers for a bargain £450 at the moment if I'm quick to be the two rears. Any thoughts? I thought - Keep it Proac to go with the D15's. I have however heard good things about the B&W sub. can I get away with a non-Proac sub? Does anyone know anything about the Tablette Reference speakers?
