Using the 1000 hours of Cartridge use, that is commonly suggested as a period that is the Stylus Life.
The Inspection and Follow Up Refurbishment Service from a Third Party Service will be near $450 from and back to the home.
Looking at like for like Cart's in relation to the Cart's original value, will be hovering close to $3K.
The owner of the Akiva Cart' can experience this for the next 1000 hours at approx $00.45c per hour. Alternatively, have the experience of being the owner of a New Cart' at $3.00 per hour, if extending to such a purchase value.
I assume the Akiva owner is informed of the Cart' being strongly suspected of being a Scan-Tech / Lyra Pedigree. Cart's from this Pedigree have loyal followers as does Koetsu's and other Japanese Brands, the era of the Cart' being produced is part of the unique flavour being desired to be maintained.
