Thanks for the tips. If I buy the UERM, I will definitely try out the copper cable. I already ordered a Roxanne universal model. It will arrive this early December. Well, since UE is offering a 20% promo, I barely see this, maybe the 1st time. I never try any UE customs, so I want to give it a try. I'm also considering the Noble K10 since Noble offer 20% promo too.
