To make the sound purer, we focus on the rectification process first, using fast recovery diodes in a series rectification setup. This approach can be seen in high-end Marantz amplifiers and also has traces in American Mark Levinson amplifiers. Then we use six 10,000µF/50V Japanese Elna AUDIO capacitors for filtering, with a total capacitance of 60,000µF, which is more than sufficient even for a single amplifier. Our cost-no-object approach is solely to provide audiophiles with excellent sound without any shortcuts or gimmicks.

As a preamplifier, it is designed to amplify very weak signals, so the power supply must be stable without fluctuations. Adding a regulated power supply is essential. The original JinSangZi units do not include it, and similar products on the market also do not, so to surpass them, you must have your own understanding. Otherwise, you will always live under the shadow of JinSangZi, which is already a benchmark. Simply imitating or replicating it will not achieve superiority, as technology is always
progressing.

Regulated power supplies also vary in quality; you can't just use any random one, as the difference in sound is enormous. We experimented with over ten types of regulated power supplies and selected one that provides balanced, atmospheric, and
high-precision sound for the C-2860 Plus. After months of adjustments and comparisons, we finalized our choice. It was a very long and tiring experiment, but the result is that the C-2860 Plus now delivers sound far superior to the original JinSangZi C-245.
It's not an exaggeration to call the C-2860 an upgraded version of the C-245.
