I am looking at setting up some 5.1 speakers, any views on this short-list for a Pioneer 434 plasma: 1. Kef 2005's in black to match but they are around £800-ish 2. KEF 1005's in black(?) as they are cheaper but still good quality 3. All-in-one Pioneer NSV1000 system to save money on the whole set-up but it means no future upgrde capabilities 4. go with KEFs with a Yamaha AV amp any thoughts - I was planning to sort out above setup for around a £1000+?
