C-2860 Plus Fully Balanced Preamplifier HiFi with aluminium remote control
Product details:
The team's efforts to create the C-2860/C-2860 Plus preamplifier were carefully considered and took into account various market demands, combined with their own 30 years of design experience, referring to the original model of Japan's Accuphase, using imported components, optimizing circuit parameters, and striving to create a super quality HI-END preamplifier that produces sound superior to the original Accuphase.
The chassis is made of all aluminum alloy CNC precision machining. Musmys has its own hardware factory department, high-end machining centers, and more than ten CNC machines. The wire drawing and sandblasting workshop is independently matched for ourselves, just to make good products, so our product quality is guaranteed.

We believe that the power supply is the most important part of the audio system.If the power supply is not good, everything is out of the question.If you want to get good sound, start with the power supply.We use EI type high-quality power transformers imported from Japan, and one machine uses 2.Musmys uses unique process design and new line connection method.The cow does not shake or cry, and you will not hear the cow cryeven if your ear is close to the transformer. This is what a good transformer should be like.
In order to make the sound purer, we start with rectification and use fast recovery diode series rectification. This method can be seen in high-end Marantz amplifiers and also in American Mark Levinson amplifiers. Then,6 10000UF/50V Japanese ELNA AUDIOs are used for filtering, and the total capacity reaches 60,000 microfarads, which is more than enough for making an amplifier. We do this at no cost just to give audiophiles a good sound,without fooling or deceiving.
As a preamplifier, it must amplify small signals. Small signals are very weak,so the power supply must be stable and cannot fluctuate. It is necessary to add a stabilized power supply.The original Accuphase machine does not add it,
and similar products on the market do not have it either.Therefore, if you want to surpass it, you must have your own understanding,otherwise you will always live in the shadow of Accuphase.It is already a benchmark. How can you surpass it by imitatingand replicating it exactly? This is not advisable. After all,technology is progressing.
There are also good and bad stabilized power supplies.You can't just take it and use it. The sound is very different.
We experimented with more than 10 stabilized power supplies and selected a high-precision stabilized power supply with
balanced sound, atmosphere and charm as the power supplyfor C-2860 Plus. After several months of adjustment and
comparison, it was finally determined that this was a very long and tiring experiment, but what we got was that the
sound of our C-2860 Pius is far beyond the original Accuphase C-245. It is not an exaggeration to say that C-2860 is an upgraded version of C-245.
The left and right channel modules are exactly the same,but the selection of parts and the pairing of tubes are very
important, which must be considered in the stability of the preamplifier. We guarantee the original imported tubes and
will not use domestic or fake ones. This is guaranteed by Musmys.The midpoint output of the amplifier board we debugged is 0,and the static current of each section is carefully debugged to make the left and right channels the same. In this way,
the sound positioning is accurate, the sound field is huge,the background is profound, clean, and pleasant to listen to.
This is the style of Accuphase.
