Yeah, replace the Red with a Blue and enjoy the improvement until you get a phono amp and cables.
Rogue Audio Sphinx V3 Integrated Amplifier / Separate Phono Preamp
I have a Rogue Audio Sphinx V3 Integrated Amplifier with a built-in phone amp. I'm having an emotional desire to upgrade to a separate phono preamp based on Paul McGowan, of PS Audio, recent post saying it was the most important part of an audio system..What budget do I need to have to improve what I currently have and any suggestions?
