Forget about purchase date in California - since 2023, consumer warranties there can no longer start before delivery date.
Your story to the effect that - if I read correctly - this manufacturer starts all their warranty periods at the date of manufacture is nonsense. In addition, it would probably be unlawful for a warranty period to run even before transfer of ownership to a consumer has taken place.
But it’s all good, no worries. You posted a post, you got replies, that gave you the gumption to go back to that manufacturer who shall remain shrouded in secrecy and ask for what you should have asked for in the first place. Glad you found a way to resolve your issue that worked for you! Audiogon works in mysterious ways! Besides, it’s a lot cheaper than therapy.
