My favorite mc cartridge for years was the GAS Sleeping Beauty Super Elliptical ($200 in 1977!). Great sound for years until the suspension failed! I recently purchased a Coral 777 (used) to replace it (same cartridge as the SB). Still one of the best overlooked bargains!
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?
