Typically one of the goals in audiophilea is accurate reproduction of the original material. Using a preamp with the various equalization used (RIAA, Columbia, Decca) , helps get you there and adapt to cross produced albums such as Beatles rereleased in the USA. Gold Note varieties with external power supply PH-10 is amazing and versatile. I’ll never get a phono preamp without these equalizations
