The rule of thumb with cables is 10% of your budget, but this is just a
guideline. It's worth putting a decent interconnect between your CD
player and amp (if you're using the analogue out on your CD player). If
you're using digital, any decent well screened 75ohm cable will do the
job (as long as it's properly made).

For speaker cables, generally the thicker the better (thicker cable ==
lower resistance), although if you're using silver cables you can get
away with a thinner cable.

Who's hijacked the thread now?

You claim vast differences between interconnects yet refuse to do any
controlled tests or claim your thousand pounds from Stewart.

The rule of thumb is that for most speakers, 2.5mm^2 cable is ok for 10 metres.
Silver, OFC and biwiring is a waste of money.
You can't hear the difference between interconnects if you don't know their price.
