Just built my new HCPC from scratch with all the bits I wanted and no expenses spared. I can tell the difference. The MAudio sound card really separates the channels so much bettter. The TheatreTek player pans Toy Story 2 Wood's Roundup smoothly. So me and t' girlfriend sat down and watched Memento. Afterwards I asked her if the system was any better. 'No. Seems exactly like it was before.' hum. So no more upgrading my HCPC, now. It ain't broke - I'm not going to keep on fixing it.
