Thanks for any input!
With the 14" 4Point you want to keep in mind its effective mass, which is 19 grams, and match that with the compliance of your cartridge. Both 11" and 14" 4Points like relatively low compliance cartridges. The reason for matching cartridge with arm using these parameters is to avoid cart-arm resonance outside a range of roughly 7-12Hz.

There is a calculator on the Vinyl Engine site that will show you the safe and unsafe frequency ranges for a given compliance, cartridge weight and effective mass. Here

Just look up the specs for the cartridge you want to evaluate.

The compliance number is a bit of an odd duck in that there are two ways to measure it. The calculator is designed for cartridges that use a measurement frequency of 10Hz. Many Japanese made cartridges are measured at 100Hz. There is no conversion. What I do sometimes is take the compliance number of a cart measured at 100Hz and multiply that by 1.5. None of this is a hard and fast rule, but it should give you some idea of compatibility.

The original Lyra Atlas has a compliance of 12 and 9.2g weight. Add in 1-2 grams for mounting screws. It should be fine with the 14" 4Point.

Another low compliance cartridge that works well with the 4Points is the Fuuga.
