Yes. I have Revelation Audio going from power supply to preamp section and diy/cryo'd Acrolink 7N P-4020 II from power supply to the amp sections of my Musical Fidelity TriVista. Both made noticeable improvements in smoothness and detail.
Will upgrading Umbilical cord power supply to preamp improve sonics
H, Is there any advantage to an higher quality umbilical cord. Cables everywhere else make improvements for me through out my system. I've never put much thought into this and don't even know where to buy or if they are even available and if so where? If anyone has done this upgrade was it a large improvement and not just subtle and what was cost per cable? Thanks
