I have an interest in cartridges that have a legendary reputation and lots of aftermarket improvements. I already own and love a Denon 103R, modified by Zu Audio. Next, I'm thinking of getting the legendary Shure V15. But, a) - there are too many to consider, and I don't know which one to get, and, b) - the NOS ones are quite expensive, easily in the $500 range. here's one: NOS Shure V-15 Type III Super-Track "Plus" Phono Cartridge & Shure VN35E Stylus | eBay here's another: SHURE V15IIIHE NOS CARTRIDGE AND NOS GENUINE SHURE VN35HE HYPERELLIPTICAL STYLUS | eBay So, the actual questions are: Are Type III better than Type IV or vice versa? Are hyper-elliptical styli better than elliptical? Are these prices justified by the merits of the carts, or is it just hype/vintage markup? If the advise is NOS - which one? OR Is the combination of current production Shure M97xE with an upgraded stylus (LP Gear N97xVL ViVid Line or JICO SAS/sapphire cantilever) better, or at least as good as those NOS carts? - It seems this route is cheaper than original NOS cart, even with JICO, but is it a better choice? The turntable the cart is likely to be installed on would be a Denon DP-1800 direct drive, with original arm. Separate thread on the merits of the Denon will be posted shortly.
