The Science of Vinyl/Analog Setups


It seems to me that there is too little scientific, objective evidence for why vinyl/analog setups sound the way they do. When I see discussions on tables, cartridges, tonearms and even phono cables, physical attributes are discussed; things like isolation, material, geometry, etc. and rarely are things discussed like wow, rumble, resonance, compliance, etc. Why is this? Why aren’t vinyl/analog setups discussed in terms of physical measurements very often?

Seems to me like that would increase the customer base. I know several “objectivists” that won’t accept any of your claims unless you have measurements and blind tests. If there were measurements that correlated to what you hear, I think more people would be interested in vinyl/analog setups. 

I know vinyl/analog setups are often system-dependent but there are still many generalizations that can be made.

For you measurement types, based on the following specs, how are each of these cartridges going to sound? Since I have had both, I know if the specs actually tell the difference in sound quality. 

Frequency Response: 10Hz - 60kHz
Channel Separation at 1KHz: 40dB
Input Load: 47K
Output: 5.0mV
Recommended Tracking Force: 1.5Gms
Stylus Type: Elliptical
Inductance: 45mH
Resistance: 475Ω
Compliance CUs: 20
Stylus Replacement: Factory
Mounting: Standard
Weight: 6.5g

Stylus: Selected Contact Line low mass Nude Stylus 
Radius of curvature: 6 x 17 µm
Cantilever: Boron
Recommended Tracking Force: 1.8-2.2 gm
Effective tip mass: 0.32 mg
Compliance: 10 µm/mN
Body material: Corian and Brass
Frequency Response: 15-45,000 Hz (±2.5 dB)
Channel Separation:
  1000 Hz: >28 dB
  50-15,000 >25 dB
Channel Difference: <1.0 dB
Output Voltage: 2.4 mV
Weight: 10.27 Gms
Load: => 47 kohms

i look at a couple of specs to determine if a cart will match up with my arm and my phono preamp. After that, I’ll let my ears determine which piece sounds better.
