I can chime in, in support of TMR Audio. I live in Florida, and have no affiliation with them, but I have purchased half a dozen different components from them. I probably kept two or three, and returned three or four within the 14 day window for returns on their certified pre-owned program. They have always been top notch, accepting my returns for a refund (since I take very good care of any equipment, and return it to them in mint condition that it arrived in if it doesn't fit well in my system.
I did purchase an Esoteric K-01X SACD player from them, and it arrived where the tray wouldn't open properly. The offered me to send it back to them for evaluation, but in the meantime, I figured out that there was just a couple of buttons needed to be pressed to reset the system, and I still am enjoying that SACD player without a problem.
Thanks Josh and TMR Audio, for allowing people like me, who don't live near any dealers to try equipment in my system, and return it if it doesn't work well in my system!
