I purchased a pair of new Mission 770 loudspeakers from TMR a few weeks ago. I'll be trading in my previous loudspeakers as part of the deal. They have been great to work with so far. I'll get my old speakers packed up this weekend, following their very through packing guidelines. TMR is paying for shipping both ways and will give me trade-in value plus sales tax difference upon receiving and verifying my speakers.
I had the option of sending my speakers in first, but I wanted the opportunity to compare old vs new within the context of my room and system before settling on a decision. Ryan at TMR has been very accommodating and helpful throughout the process. I'd be happy to deal with them again if the need arose.
