Picture the stylus like a wheel on a car. The stylus has micromotion as it tracks the groove on a record and that motion is absorbed by the suspension. Just like the wheel on a car moves over small bumps in the road but the car remains fixed. In both cases in regards to the micromotion and inertia of the stylus and the wheel, they are very small compared to the mass of the tonearm or mass of the vehicle. So that micromotion causes little or no motion in their relatively massive counterparts. But when the stylus moves over a warp in the record, for example, now the entire tonearm must move in response to that warp. Consider that a macro-motion. In this case, if the tonearm has too much interia, the tonearm raises up to ride over the warp but takes too long to come back down resulting in a skip. Similar sitation in a car- a dip in the road or bump in the road causes the car to move up/down, but if the car has too much inertia, then it leaves the road surface. In both cases, a car or a tonearm, the spring rate and the effective mass affect how they respond to those macro-motions.
Cartridge Loading and Compliance Laws
After reading into various threads concerning cartridge/arm compatibility, then gathering information from various cartridge manufacturers I am left feeling confused with head spinning a bit.... Ok, cart compliance I get, arm and total mass I get, arm/cart compatibility and the whole 8-12 Hz ideal res. freq. range I get. But why on earth then do some phono cartridge mfgs claim their carts are ok to use with med. mass common modern arms when they are in the highish 20-35cu compliance range? Am I missing something??
Ie. Soundsmith, VanDenHul, Ortofon and who knows, maybe more??
From what I gather, below 8Hz is bad and above 12Hz is bad. If one is less ideal than the other, which is worse I wonder, too low res. freq. or too high?
