Summary of key elements of upgrade

Upgraded model of Lundahl input transformer for improved speed and dynamics.

Circuit design revisions to input circuits that lower distortion and improve dyanmics and resolution.

Cryo-treated, solid core ultra-pure input wiring and 12GA stranded audio-grade output signal wire to binding posts.

Revised capacitor bank (current storage design) that increases total storage (capacitance) and also lowers power supply impedance, which translates to faster current delivery to the output stage.

This all translates to the following in terms of sonics:

A more open and resolving overall presentation.

Tighter and faster bass and transients.

Improved speed and dynamics, whilst still retaining tube-like midrange qualities.

Improved soundstage and low-level cues due to an even LOWER noise floor.
