Contact Alasdair Patrick (Apatrick@audioquest.com) and he will take care of you. Great guy and Audioquest is a wonderful company to deal with, along with Lyra, of course.
Audioquest will email you a RMA form to fill out you email it back. They will then send you all the info needed to return it to them and they will forward it on to Lyra in Japan.
