This is what you meant ?
If you’re looking for 40 Anniversary Concorde from KAB then Fine Line or Fritz Geiger option is the best.
The price is high and you can’t change the alignment method using Concorde cartridge, there is no adjustment of overhang. This is really not the best cartridge and instead of paying that much you can buy some amazing MM or MI cartridges from the past with much better sound quality than any Concorde with any type of styli. This is MM cartridge and cantilever is very cheap and soft aluminum, again, you can pay the same price for a better cartridge with advanced cantilever, stylus.
KAB offers some upgrades for the most popular (none audiophile) gear and it’s good for those who already have that gear and willing to upgrade a bit.
But the best upgrade is to buy another cartridge from the start. I tried all Concorde models in the past (15-20 years ago), it was $150 cartridges for professional needs, they are low compliance designed for high tracking force. An entry level cartridge for high price (for an entry level) and any simple $100 Grado MI killing it!
If you want an audiophile grade cartridge then Stanton
CS-100 WOS, Pickering
XSV/4000, Pioneer PC-1000 mkII, Grace F9, Victor
X1IIe is the way to go with $500-750 budget max.
