I agree with you 100% that the various recordings and masterings issued and manufactured may not be faithful to the original sound of the band. However a system’s degree of fidelity can be quantified in how faithful it is to the actual recording it is presented - no more no less. So there is such a thing as high fidelity and the higher the fidelity the less altered the sound should be!
Do you know of a good recording of Moby Grape - love that band?
Are you an engineer? You talk of L R and C but do you understand the relative impact that these factors play and do you understand how important component design is and component matching is in order to minimize any artefact from bits of wire....
