For a traditional balanced design, you must have both the input and output balanced in order to get the added boost in performance of balanced amplification. With our new state-of-the-art design this limitation no longer exists. This means you can use either the balanced input or output, and still have the sonic improvement of balanced amplification. (About a 70% of improvement which input + output balanced amplification can achieve).

The lowest photo set shows a very special version with a bigger Transformer and big tube rectifier with 3 inputs. As well it includes a solid-oak chassis with metal on top (additional cost applied)

(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 : (+ C$200)

Special designed "Super-Drive" circuit, output impedance lowered to 200ohm (can drive any power amp inputs 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 pieces of power tubes being installed . With this level of upgrade, just add another $50 and you can have a headphone output with enough power and current to drive your headphone directly.

Level 2 upgrade : (+ C$500)

Level 1 upgrade + Enhanced input circuit design with increase of max. input levels , further lowering of distortion and increase dynamics, as well as better air and openness . Enhanced components quality for better sonic reproductions with higher resoltuions.

Level 3 upgrade : (+ C$800)

Level 1&2 upgrade + Upgrade power supply with bigger transformer and stronger filtering circuit as well as enhancement in components for further sonic enhancement with more 3D holographics soundstage.

Level 4 upgrade : (+ C$1000)

Level 1&2&3 upgrade + Enhanced transformer with 5U4G tube rectifier for better air , smoother and sweeter sound quality
