Thanks people for all your posts. Interesting read. I like the cheap options only because they are cheap but to be honest I wouldnt be happy with them long term. I've been quite drawn to the Bose L1 + B2 sub + Bose Mixer. That setup would set me back around £2500 but it should be close to my computer sound system which is what I was looking for. All I need to do now is figure out how to get £2500 .....and some talent to justify it!
