SVPER QVATTVOR Utility True Balanced MC Step-Up Transformer with optional MM/MI Step-Up transformer module
Combining the strengths of the all QVATTVOR line and maintaining the transparency of the 4x4 Reference Model
was not easy: presented at High End Munich 2021, the fully balanced QVATTVOR showed the direction in which we began to move in maintaining a balanced form of the MC cartridge signal.
Simultaneously, over the past few years, thanks to many feedbacks, we have come to understand the need to expand nonstandard functionality and implement a number of solutions aimed at reducing vibrations and improving shielding in general.
As a result, the new SVPER QVATTVOR has got a damped robust steel housing, inside which, in addition to the quartet of fully balanced Step-Up transformers from the 4x4 Reference
Model can be installed an additional shielded module with unbalanced MM Step-Up transformer line with 1:2 ratio.
The Demagnetizer button is also brought to the front to easy to use. Heavy aluminum front panel with original solid sphere knobs on black glossy finish gives a clean stylish aesthetics.
