edit: This post was written having only read up to post #71 - it looks like discussions moved on since then.
I've just been reading the comments of some NASA engineer who has apparently designed the most precise speakers ever made, and he doesn't sound keen on audiophile cables:

I don't know much about electronics, but I can't really visualise how bi-wiring helps. It's meant to help by preventing signals and resistance from treble and bass interfering with each other, but if both the cables are connected at the amp end, surely any interference will still occur? One explanation I read is that bi-wiring could make the bass and highs slightly out of phases and easier to distinguish, perhaps creating an effect some prefer.
The SHB site mentions 'Noise Suppressor Valves' which remove the hum from valve amps... but how? Do we really want little things put into speaker cable to interfere with the signal somehow?
What's going on here! I've read in a few places that bi-wiring really helps the Dalis too. My science isn't up to this.
I'm also considering going for the Leema Pulse amp, and leaving the CD player for now. I think the amp is a pretty good match for my speakers, and not a bad deal. I've been checking e-bay for local second hand stuff, but not much has come up so far.
PS: I'm not called Dean. Have people been calling me Dean? That would explain why I was so confused for a few pages. Sorry if I ignored anyone's comments, but when it was addressed to Dean, I assumed it was meant for someone else!
Thanks for all the help so far.
