I forgot. In terms of record wear there are other variables than stylus profile like compliance and tracking force. Styli with larger contact patches are a benefit given the same VTF. SRA and azimuth have an influence but not as much as you would think as long as they are within reason. I think they are more important for separation and high frequency performance. Today’s cartridges are significantly superior to the ones we had in the 60s and 70s particularly when it comes to build quality. It is hard to find one that is objectionable. We really are talking about nuances.
Is elliptical the best stylus profile
In my experiences, it seems that elliptical shaped stylus track better and pretty much have the same amount of detail that a line contact has, maybe a little less. The difference, again in my experience is that the line contact needs to be set up perfectly for good performance. How many of us are experts at setup. Cartridge manufacturers, Why not just use elliptical shape and give everybody a break?

Surely the best stylus profile is the stylus profile you like best. Hard to see any reason to make it more complicated than that. Sure, tracking *might* be a slight factor, but like mijostyn says above it's hard to find a modern cartridge which doesn't track quite well or better. I suppose if you play the Telarc 1812 every other day it could conceivably be a significant issue, but I'd happily put a good few quid on 95%+ of all tracking problems being down to bad set-up or a mismatched tonearm/cartridge combination. |
agrippa Sure, tracking *might* be a slight factor, but like mijostyn says above it's hard to find a modern cartridge which doesn't track quite well or better.That depends on what you mean by "doesn't track quite well." If you're stating that most modern cartridges will stay in the LP groove, I'd agree with you. If you mean most modern cartridges can sail through things like all six tracking bands on the Shure V15 Type V Audio Obstacle Course LP, I'd disagree, based on my own experience. In fact, Shure pressed those LPs specifically to show the tracking limitations of its competition, and some have not improved much - or at all - since. |
cleeds it takes more force to move the stylus of a less compliant (stiffer) cartridge than a more compliant (softer) cartridge. That force is supplied by the turntable spinning through the vinyl of the record groove. In other words the vinyl has to transfer more force to the stylus of a less compliant cartridge than the stylus of a more compliant cartridge. More force means more wear. The approach to cartridge design has changed quite drastically since the 70s. We use to have crazy compliant cartridges like the V15, Pickerings, Stantons, Empires tracking at 3/4 gram with elliptical styluses in crazy light tonearms. Remember the Infinity arm? Now we have stiffer cartridges with line contact styli in larger arms tracking at 2 grams. The other big cause of record wear that I forgot to mention is mistracking. You can always tell when a record has been mistracked. The heavy passages get crackly for lack of a better term. The stylus starts jumping up and down in the groove digging in a little each time it lands. Sort of like the difference between walking on thin ice and jumping on it. A cartridge mistracking at 3/4 gram VTF will cause a lot more damage than a smooth tracker at 2 grams. |
