Of course, that would be spamming this thread. I post these traces to support my points, support others that cannot do these traces or disprove assertions.
For those looking for differences between hardware setups:
I have 2 analog systems:
System 1 consists of Project RPM9 —> 9c Tonearm —> Benz Micro Ref3 Silver cartridge (Iron Cross, micro-line, boron cartridge) —> Whest Ref PS30 Phono stage
System 2 consists of JVC L-FX4B (this was my first TT and is over 40 yrs old, recently died) —> Stock tone arm —> Audio-Technica AT85EP (MM, elliptical) —> Parasound Zphono
My ADC = Tascam DA-3000
A few years ago, I ripped Fleetwood Mac’s Monday morning on both systems.
Here is what the spectrum for each looks like (system 1 first for all traces):

Not remarkably different. But if we start looking at other aspects, differences start to appear.

In this test scenario, it's challenging to pinpoint where the differences in the analog chain arise, as each chain is completely different. The key takeaway is that focusing solely on frequency response (FR) doesn't provide a complete picture. As shown in the spectrum plots above, the two systems appear quite similar from that perspective.
