I believe every piece of audio equipment has its own sonic signature. E.g. CD transports, cartridges, tone arms, turntables, preamps, amps, cross overs, speakers, interconnects, basically every component, part, and wire in (and around, e.g. power supplies) the audio signal path will have its own sonic signature, whether designed or not. Technically, a sonic signature is called a transfer function, but we will get to that shortly. I also believe there is a direct correlation between what we hear

Recommended reading first The reason is that I am not going to reiterate the baseline components and measurements of my test gear already covered in that post.
Here is a high level block diagram of my test setup:
On the left side is my HTPC with both JRiver MC 17 and JPLAY mini installed. The test FLAC file is the same Tom Petty and The Heartbreakers, Refugee at 24/96

In part 1, I used a null test technique to show that both FLAC and WAV (lossless) file formats are identical. In this post, I have expanded the null test to cover off playing the same FLAC and WAV files dynamically from JRiver and capturing the audio waveform after the Digital to Analog conversion and analog line output stage. Here is a high level block diagram of my test setup:
