I went for the WHF special offer on the Klipsch Image X10 - ordered yesterday and arrived this morning.
At first my iPod Touch was giving an unbalanced output (left headphone was quieter) which made me think it was the Klipsch, but no, I took my iPod back to Currys as it also had a cracked screen, and I've got some vouchers heading my way which are going on a 32GB iPod Touch.
At the moment I am listening through my Mac and CA amplifier. Thanks for your information, I'm not sure how much they can improve to be honest, considering their size and weight. But overall, yeah as I said before, I'm chuffed!
