Maybe think about getting that extended warranty.
Does using the XLR-1/4" adapter add substantial weight at the end of the cable? I'm just thinking about whether the downward pull would be too much if the cable is hanging straight off the table.
I just have to give a shout out to Steve Eddy (owner of Q cable) for an awesome job on his cables! I just received a Q cable today with additional adapters to use my HD800 and of course my LCD-3 and wow I am loving these cables. Looks so beautiful and the build quality is hands down amazing! Love it! I was a skeptic at first but sonically I feel there is an improvement but the quality, lightness, and reduced micro phonics is simply worth the upgrade. I definitely gives it two thumbs up and highly recommend to anyone who want to upgrade there stock cable. These cables are so much lighter than my stock cable and looks a million times nicer! Thank Steve for such great service and product! Listening to my LCD-3 with Q cable and Bryston BHA-1 as we speak.
