this series of our products, the power supply is separate from the
amplification unit. This architecture has an advantage of minimizing
the background noise and hum which is induced by the transformer coupling.
Up-grading this unit is made easier for you as the same power supply
unit can be used and one more amplification module can be purchased.
Or you can use the same amplification unit and buy an enhanced power
supply unit to boost the overall performance.
The 12AX7 Transformer
amplification module uses an oil capacitor as a power filter and employs
high grade NOS output transformers, so the most natural sonic performance
can be preserved. The tubes used are the most common 12AX7/ECC83/5751,
you can also put in 12AU7/5814A/12AT7/ECC81/ECC82 for fine tuning
of the tonal quality.
uses a no-negative-feedback design, so a superlative open sound stage
and airy feeling can be achieved. At the same time a very special
circuit design and fine-tuning technique is imbued in this unit to
make those small tubes sound like a big tube (big tubes sound more
natural and real in some instances) but still retain the advantage
of small tubes (which is pin-point focusing and tighter bass control)
. So with this pre-amp you can obtain a RICH, SWEET, OPEN, AIRY, GOOD
FOCUS and TIGHT BASS PUNCH in one single unit.
The circuit design
is our very special copyright design, which offers a significant improvement
in focusing, dynamics, depth, and width of sound stage. It is our
belief that the sonic performance will better those products asking
over US$6,000-10,000 in the market. Experience this awesome product
for yourself and you will know we are not just talking .
This unit is all
hand-wired. No transistors and no printed circuit board ensures the
best open and natural sound quality. Satisfaction as always is guaranteed.
This model of pre-amp
is mostly suitable for classical (chamber or orchestral), opera, vocal,
country, slow pop, easy listening, jazz, and slow rock.
