The ACSS is a non-feedback technology made with fully
discrete amplifiers. Most people know the global feedback design can
offer better specs in test measurements, and non-feedback can't do well
in test measurements but can offer better sound for the human's ears.
Here is a conflict of the classic circuits. But the ACSS opens a new
field, it can offer a least coloration sound which is more neutral with
very low distortion and high linearity. So it can retain the dynamics,
detail and neutral sound but not sound bright or harsh.
Massive use of high
power parts and robust regulated power supply guarantee vigorous current
output that drives most existing loudspeakers. The new ACSS module
adopted in current signal handling of C-10 sustains the musical signal
intact, bringing dynamic response and acoustic fidelity to an
The C-10 provides ACSS input and XRL input.
When C-10 works with ACSS preamps C-3 or C-8 or C39, it shares the
isolated control circuit of the preamp causing even better signal
matching and controlling. The fruitful result is: far higher s/n ratio
and lower distortion than ever expected.
Balanced signal throughout, an entire class A current gain circuit.
The music signal is transferred in this ACSS form till it reaches the
output stage. ACSS musical signal would be directly transferred to ACSS
signal amplification module in the amplifier for signal gain processing.
Balanced bridging circuit structure doubles not only the scale of the
circuit but also the cost.
All signal gain is under current form, achieved by the unique,
superb open loop multiple output current mirror. Current mirror that
deals with the last stage of current gain utilizes 36 pairs of high
speed and high linearity transistors. Incomparably precise and ultra-low
distortion in the gain signal is the result. The signal path is balanced
throughout and all transistors work in class A mode.
Relying exclusively on the feature of ultra-low distortion of the
very linear ACSS amplifier, the music is unbounded, euphonious and
distinct even without negative feedback.
The ultra-low distortion, independent, yet intra-complementary
front driving stage and the 0DB output stage provides the back output
stage with hyper-speed, hyper-linearity regardless of low impedance or
For purity of output signal, high performance regulated power
circuits are employed in the power supplied to the low voltage and gain
stage. Influence from AC fluctuation is minimized.
All regulators work in current convert mode which excels in high
bandwidth, low output impedance and great immunity against interference.
