How does that relate to what I said, you seem confused.
If your system isn't first capable of High Fidelity (accurate) playback of the source, your lost before you begin.
That's "sound quality" first. If you later want to inject some EQ or whatever to make that old shellac sound
more pleasant, fine.
If you instead chose components and speakers that are distorted in some way but "make" that 1930s recording sound nice, but not whats really in the grooves, you system will distort everything you listen play in that manner.
