Hi Joe,
My situation was clearly a case of not knowing a good. I have since been set straight, and lately by you.
I contacted Scott many moons ago, right after my purchase. He verified that it was of the ‘B’ iteration. I may write to him as you suggest.
I found a good guy helping with Lumi repairs. It has been trouble free so far. He has restored the ‘bypass’ switch, and I finally found the proper loading for the ZYX. Everything is good.
He did mentioned that a direct comparison between a Lumi phono stage and a Vendetta was done in his shop years back. Vendetta won hands down. I am not looking to change, mind you. But...........In any case, Vendettas are near impossible to find.
