My only experience with TMR was buying an inexpensive ($200 range) power cable from them, and was surprised to get a follow up call shortly thereafter to be certain I was 100% satisfied.
Having sold high-end audio in brick and mortar stores for many years, I can say with confidence that this level of customer service and follow-up is uncommon on new gear, let alone used gear.
Admirable restraint on Josh’s part, and that will surely pay off in future sales.
I too hope that the OP takes some time to reflect. Admitting when we are wrong and making amends is good for the soul.
