The chassis is made of all-aluminum alloy CNC precision processing. Miaosi has its own
hardware factory department, high-end processing centers and more than a dozen CNC
machines, and an independent wire drawing and sandblasting workshop, just to make
good products, so the quality of our products is guaranteed.
The transformer is imported from Japan, which is incomparable to domestic DIY. The
quality is guaranteed. Iron cowling is used as shielding and epoxy sealing is used to
effectively prevent magnetic leakage. Details determine success or failure.
The whole machine uses 6 original Japanese "ELNA" audio dedicated AUDIO filter
capacitors, and the whole machine filter capacitor reaches 60,000 microfarads, which
is an important guarantee for the output strength of the pre-stage.
●We believe that the power supply is the most important part of the audio system. If the power
supply is not good, nothing can be discussed. If you want to produce good sound, start with the
power supply. We use EI type high-quality power transformers imported from Japan. One machine
uses 2. Miaosi adopts unique process design and new line connection method. The transformer
does not vibrate or make noise. You will not hear the noise even if you put your ear 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 Yinna AUDIO are used for filtering. 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
Golden Voice 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 Golden Voice. It is already a benchmark. How can you surpass it by
imitating and replicating it exactly the same? 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
supply for 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 Golden Voice 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 should be considered in the stability of the whole
machine. We guarantee the original imported tubes, and will not use domestic or fake ones.
This is guaranteed by Miaosi personality. 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.
