Level 1 upgrade : (C$200)
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 tonal quality
Level 2 upgrade : (+ C$500)
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.
Level 3 upgrade : (+ C$800)
Level 2 upgrade + Stronger filtering circuit as well as enhancement in components for further sonic enhancement with more 3D holographics soundstage.
Level 4 upgrade : (+ C$1200)
Level 3 upgrade + Enhanced transformer with 5U4G tube rectifier for better air , smoother and sweeter sound quality as well as improvement in sound stage
Level 5 upgrade : (+ C$2000)
Extreme newly designed circuit upgrade with super low S/N down to -95db, output impedance lowered to 100ohm, maximum input level increased to 10Vrms , further boosting of dynamics , no need for tube matching can also get most balanced L/R channel gain and sonic performance. Gain = x5 / x10 selectable. Enhanced components to improve resolution and details with even better tonal quality and air. With this level of upgrade, both specificiaton and sonic performance can easily surpass others pre-amp with almost any price range in market.
Additonal up-grade options:
solid-oak chassis add $150
0/180deg phase switch add $150
(Note: The price quoted is a special deal for newly order unit only, modification of existing unit price will be higher)
