I have cognitive dissonance thinking that an elderly Japanese gentleman is the last living repository of such skill and knowledge. What - when he dies, Lyra effectively goes out of business?
You have no idea what you’re talking about. Mr. Jonathan Carr is younger than most of you and contribute on this forum from time to time with valuable information you can’t find anywhere, he’s a cartridge designer. What is really strange is to send Lyra to someone else for rebuild pretending for upgrade in sound.
Different cartridge is always a good idea, we like many cartridges, not just one from any particular brand, except for people who does not have much experience with cartridges.
Refurbished Lyra is not the Lyra anymore, once someone else replaced cantilever or even stylus tip with something with different mass/size etc.
