Let me tell my factory story. I obtained a M3A with Gold phono board from a gentleman who was connected with the music industry. He obtained it new from AI and paid industry pricing for it (cost). I sent it to AI for a checkout and update. I specifically paid to have them swap out the black face plate for a silver face plate and paid for the return of the black knobs so I could use them when I wanted to swap out the silver knobs. So I essentially paid for a new silver face plate and silver knob set, as well as return of the original black knobs with the understanding that AI would keep the black faceplate only.
When AI received my unit, Art Ferris called me about this unit. He told me that he was livid that the original owner sold it to me and asked how much I paid for the unit. He then told me that updating the unit would be done as an out-of-warranty situation. He said their preliminary finding was that over $800 of work was needed to bring the unit up to spec, plus the up-charge for the faceplate/knob set exchange. That was in like October of 2005. I waited about 4 months before calling AI to inquire about my unit. Another guy named Jerry told me that my unit was next up for repair and updating. After waiting another 3 months, I called AI to inquire about my unit. This time Art answered and told me they were testing the unit and that it would ship soon. After another 3 months, I left several nasty voice messages with Art, complaining about the fact my unit was in the AI factory for over 10 months. About one month later, I got my unit back. They charged me for new tubes, which I didn’t ask for. I never got my original black knobs back either. Art said he didn’t recall that agreement.
