It depends on what you want to spend and what your personal preferences to sound are, everyone's ears and music are different!!! You have a good cartridge but wear on the stylus is hard to judge if you don't know how much it has been used. Chances are that the stylus is worn tho. Audio Technica AT95E can usually be found for under $50.00, Shure M97XE can be found for about $70.00 On the low end there's the Ortofon Omega under $35.00, might not be the best fit for your Dual tho, ultra light cartridge! If you have some nice new vinyl you will want a stylus gauge. There are protractors downloadable in the library here. Do a little searching around to see what may be best for you, sometimes it's kinda a crap shoot now that you have to order online. If there is a shop in your area that sells TTs or cartridges you may pay a lil more but he might set it up for you and get it right for you. If your V15 was set up right to begin with you can just pull out the old stylus and pop in a new one, should check your balance and anti skate tho. I'll betcha this made it easier for you to figure out!!!! Glenn.
