This is a fully balanced input and balanced output state-of-the-art pre-amplifier which boasts an ultra high current tube rectified and tube regulated power supply, plus a choke with NOS and oil filter capacitors . A separate filament Tx and high-voltage Tx is included to enhance the dynamics and clarity. A Choke / bypass switch enables users to fine-tune the speed of this pre-amp. This super pre-amplifier is specially designed for those who like both very sweet sound quality , high dynamics, very musical, high definition, and a very detailed and deep sound stage. (Everything good that you are expecting is inside this pre-amp! )
