The Best customer service I've experienced in the last year is with a small company BMI Virtue Power Cords. The owner designer, Brian Introcaso worked with all the custom situations for upgrading my power cords. He spent ample time in answering all my questions and designing my Eel power cords to work in my system. Very happy and pleased.
Best and Worst customer service?
My vote goes for Sonic Frontiers, as Best! I was contacted within an hours, after e-mailing a question. Wery friendly and helpfull!(they can count me-in on the next purchase) Thw Worst? Linn audio! It's been over a month since i submited a Q! I am stll e-mailing the question...i am sort of amused by now!
