Retuc01 - charts and graphs mean very little. The cartridge sound is the important consideration. If you like it fine, however, the fact that it is so old is suspicious. Rubber parts deteriorate from ozone in the atmosphere...things harden and soften.... I would have it checked out by Dynavektor..it probably needs a rebuild.
Need help with phono cartridge selection
I have 2 Dynavector phono cartridges. Ultimo 20C and Ultimo 10A. I know that the 20C is a low output MC and that the 10A is a high output cartridge. I have sampled half speed mastered vinyl with both mounted on a Denon DP 30L II turntable and have experienced pluses and minuses with each cartridge. I am using a Hafler DH500 amplifier with a PS Audio 5.6 Preamplifier for electronics and Snell Type A loudspeakers. Simple question...with this setup... which cartridge should I keep ? Ultimately my ears must be the judge and I understand that, just looking for opinions.
