I've had the 2.1 since 2010. Ready to upgrade now. Seems like nothing else is better though even for little higher price range... The speakers retain their value... they're going used/refurbed for the same price I paid for them new 3.5 years ago. I'm on my third sub and second right...

A few months ago my left speaker stopped working on the MTH50's. I'm debating sending to AudioTechnica for repair. Any one have any experience with their Service Center? I wanted to get an estimate but seems like I have to send it there and pay $30 if I decline the repair.   So before...
