It is the compliance of the cartridge not the weight that dictates the use of a higher or lower mass arm. The objective is to place the low frequency resonance of the assembly above typical record warp and eccentricity of 7 - 8 Hz, therefore about 10 - 12 Hz. Resonance is a function of cartridge compliance and arm mass. This relationship has been charted for audiophile convenience but I can't find mine (several cleanings and moves) so I can't quote example numbers at the moment. General rule is high compliance / lower mass arm, low compliance / higher mass arm. I like the Dynavector high output moving coils - have a 20A and have used 10X4 (both older versions). I see DV now has a newer 20 model in both high and low output versions which may be worthy of your consideration. Both (older) are very detailed but the 20 is less "hard" in your terms. I am not familiar with the DV arm. Good luck with your choices.
Advice on cartridges!
Hi, everybody! I´m new in this hobby, and I´d appreciate very much some advice regarding phono cartridges. I´m using a Sumiko Blue Point Special MC, with Dynavector 507V tonearm, Oracle turntable, Aragon 24k preamplifier, Aragon 4004 amp and BW Matrix 803 Series 2 speakers. I´ve been using this cartridge for 6 months and I find the top bright and a little hard. I´d like to purchase a cartridge that could match in a more musical manner with my system. Advice is welcome. Thanks for your interest!
