:help: I'm considering buying the kef 2005.3 speaker package at a very good deal from hifix for £530 (best deal I've seen anywhere), will it be compatible with my Pioneer VSX921 Amp and will it sound good. I've read online there seems to be issues with the kube 2 subwoofer switching off automatically on a lot of other amps but can't find any forum posts for the VSX921 problems. Also I noticed that there are 2 audio connections from the subwoofer that output to the amp, I only use 1 on my current setup, do I have to use 2?
