line stage single-ended 12AX7(ECC83) transformer output super hi-end tubes pre-amplifier

In 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.

This pre-amplifier 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.
