I'm taking my first steps into the home cinema market and will be geting the Onkyo TX-SR608 along with the Jamo style speaker package. I was also looking at whether it is worth purchasing something like the Ecosse Big Orange power cable to upgrade my TV's 'out of the box' cable. Is it worth taking this step and also, should a mains cable like that be plugged directly into the wall to maximise it's benefit or does it matter if it goes through a 'multi-plug' adapter as i currently have a bank of 8 hooked up?
