Model no:   QA-1001 (designer series) 

This is our starting Designer series model of pre-amplifier, in this series of products there is no compromise in either sound quality or external appearance. We attempt to make this aesthetically pleasing without loss of sound quality. That is the purpose of this special series of products. Of course the cost is slightly higher due to a more complicated chassis design, but you will find out that it offers tremendous value.

The photos shows two different versions of chassis for this model, you might find it hard to believe they are an all MDF wood chassis. The use of wood in tube gear is sometimes preferable as every tube exhibits microphonics, they will pick up their surrounding's vibration pattern. Wood construction is the best way to alleviate vibration pick-up, so we use MDF as the chosen material. At the same time some people prefer the look of metal, so we try very hard to make a wood chassis which looks like metal. This state-of-the-art manufacturing process is reflected in this series of products.

This pre-amplifier uses a no-negative-feedback design, so an open sound stage and airy feeling can be achieved. At the same time a very special circuit design and fine-tuning technique is imbued to this unit to make the 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 have a RICH, SWEET, OPEN, AIRY, GOOD FOCUS and TIGHT BASS PUNCH in one unit.

This unit features both XLR balanced or RCA single-ended input and output capability, the circuit is our very special copyright design, which can show a significant improvement in focusing, dynamics, depth, and width of sound stage by employing the input or output XLR balanced connections. For most other products in the market you must use both input and output XLR balance connections to get the balanced amplification’s sonic improvements. Of course you can just use RCA input and output for this pre-amp , and the performance will still be better than those products asking over US$10,000 in the market we believe. Experience this wonderful product for yourself and you will know we are not just talking.

This unit is all hand-wired, has no transistor regulators or printed circuit board, so the best open and natural sound quality is ensured. Satisfaction as always is guaranteed.
