What I can tell you is that I replaced the stock umbilical in my ModWright Sony HAPZ1-ES and it made a stunning improvement. More than any other PC or IC replacement I ever tried. It was like a component upgrade. I had one made for me by Audio Magic. It was one of their Liquid Air designs, which I believe are no longer available. Like anything else, this is always going to be a hit or miss deal. The only way to know is to try it.
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
