Thanks. I had received my T1 over a month ago but sent it back to have them reterminate them for balanced so I could use them with the HDVD800 that I was waiting for. I just received them both a week ago. Been letting them run during the day so that they could break in. I'm guess that I'm around the 100 hour mark right now.
By the way, the T1 I order 1 1/2 months ago and received (initially) about a month ago have a serial number in the 13xxx range.
