It includes original accessories such as a remote control, power cord, original box, and extensive documentation including the original owner's manual and instructions for tube bias adjustment. The unit is praised for its beautiful sound and reliability, with NOS tubes installed and low hours of use. The design philosophy emphasizes refinement over redesign, maintaining the core Mu follower circuit topology while evolving around it for improved performance and harmonic integrity. The preamp has four knobs and a push-button switch for straightforward operation and includes custom jumpers for gain adjustment. It is highly regarded in the audiophile community for its musicality and 3D soundstage rendering.
