Detail of the Current Conveyor Technology
Precision 3 is a discrete design
applying the latest ACSS technology which improves the RCA
connection to be able to sound as good as the ACSS connection.
It seems complex, but in fact it is most straightforward design
in the world. There are a lot components in the power supply
providing rich and clean sound. The Precision 3 power amp has a
single ”§voltage" gain stage to process signals, but works fully
in ACSS mode; which in fact is a current gain stage instead of
the standard voltage gain stage. The voltage gain state applied
by almost all manufacturers requires at least two or three
voltage gain stages. We implemented most elementary and shortest
signal journey resulting most neutral and cleanest sound.
Precision 3 applies
ultra-low distortion single stage ACSS amplifier soldered
directly on the motherboard to reduce noise floor even more. The
gain stages and pre-buffer stages are all designed to work in
pure class A .
The diamond cross output stage
design avoid "switch distortion" as good as the best class A
The ACSS is a non-feedback
technology is designed with discrete amplifiers. Most people
think the feedback design offer better specs in test
measurements, and non-feedback isn”¦t as good. Putting the
measurements aside, non-feedback offers more pleasant sound for
the human's ears. This is a pyridoxal conflict of classic
circuits. Our developed ACSS named technology opens a new field:
It can offer a neutralsound with very low distortion and high
linearity. Retain the dynamics, detail and neutral sound without
sounding bright or harsh.
All signal gain are in current mode,
achieved by the unique, superb open-loop multiple output current
mirror. 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.
Massive use of high power parts and
robust power supply guarantees vigorous current output that
drives almost every loudspeaker.
Precision 3 applies two channel
diamond non-feedback output stages composed of 4 transistors,
every transistors can handle 150W / 15A . The power supply
capacitance is over 40,000uF.
The Precision 3 have very wide
frequency band with excellent phase distortion, and boost the
amp to have excellent detail and dynamic reproduction.
Precision 3 has RCA single ended inputs and
top grade proprietary ACSS current signal inputs. No matter what
kind of signal it is input .
Solely audiophile grade components
being used, e.g. 0.1% KOA resistors, WIMA caps, and custom
ordered NOVER (UK brand) caps.
