Extreme series line stage full balanced pre-amplifier | |||||||||||||||||||||
This is a fully balanced input and balanced output state-of-the-art pre-amplifier with our newest new age circuit design which is totally differ from the other pre-amp series. The QA-8001 boasts
ultra heavy current tube rectifiers with use very common power tubes
like 6550, KT88 or even KT100. A very special transformer implimented
in this unit to enhances the dynamic range and naturalness to a new
extreme. This pre-amplifier is built with no compromise in component
quality, and it's superlative sound can readily be heard in the delivery
characteristics: very sweet and realistic rendition, with ultra high
dynamic range, musicality, high definition, and a very detailed, deep
and width sound stage. Every vocal and musical instrument will have
their own position of depth without interfering with each other but
just single harmonically together. This pre-amp is suitable for any
type of music reproduction, we feel it's performance is unsurpassed
by competitor products in any price range. This pre-amp impliment both AC and
DC filament in the same unit, which can have both musical and sweet,
as well as dead quiet with tight bass punch. The output buffer stage can change
with over 10 different types of tubes: (6G6/6L6/6V6/6Y6/6K6/EL34/6550/KT66/KT88/KT90/KT100...etc)
for exact tuning to match the rest of your system.

(Note: The price quoted is a special deal for newly order unit only, modification of existing unit will be around $300 higher than the following prices due to more works for disassemble of the original circuits) Level 1 upgrade : (free of chatge ) Special designed "Super-Drive" circuit, output impedance lowered to 200ohm (can drive any input from 600ohm up to infinity) with better bass control and punch , better definition and improved in overall tonal quality. By adding this upgrade, it sounds like the output with 10 times tubes being used. With this level of upgrade, just add $50 and you can have a headphone output with enough power and current to drive your headphone directly. Level 2 upgrade : (free of charge) Level 1 upgrade + newly designed input circuitry for further lowering of distortion and increase dynamics as well as better air and openness . Enhanced components quality for better sonic reproductions with higher resoltuions.
