SUQIYA-Reference Accuphase C-2860 Plus Fully Balanced Preamplifier HiFi Audiophile Preamplifier with Remote Control

The C-2860/C-2860 Plus preamplifier is created after careful
consideration and consideration of various market demands,
combined with 30 years of design experience,
referring to the same model of the original Japanese Accuphase machine,
using imported components, optimizing circuit parameters, and making its sound surp
ass the original Golden Voice. It is an ultra-high-quality HI-END preamplifier.

The chassis is made of all-aluminum alloy CNC precision processing.
We have our own hardware factory department, high-end processing centers and more than
a dozen CNC machines, and independent wire drawing and sandblasting workshops,
just to make good products, so the quality of our products is guaranteed.

Note: Power cord not included

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.
Miaosi uses unique process design and new line connection method.
The cow does not shake or cry, and you will not hear the cow cry
even if your ear is close to the transformer. This is what a good cow 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 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 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? 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 must 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.
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 Jinshengzi.
