UNUSUAL DESIGN TO MATCH THE UNUSUALLY HIGH SOUND QUALITY

Following traditional audio principles and maintaining a low centre of gravity, two transformers are mounted on the main frame and represented in the unique external design, invoking an impression of fine modern architecture. Furthermore, thanks to a vertical three-dimensional structure, the transformer is located immediately above the power supply board, minimizing the power supply path, and contributing to a design that delivers both high sound quality and external elegance.

ELEGANT ROTARY DIAL

The robust weighty chassis is comprised of thick aluminium, and in addition to that exquisite main frame, aluminium is also used for the master volume and mode selector dials. Moreover, an abrasive sandblasting process has produced a high-grade textural feel, contributing to the elegance of high-end audio right down to the smallest detail—delivering a supremely tactile experience when using the HA-L7A.

OLED DISPLAY WITH BRILLIANT VIEWABILITY

The top panel of the unit features a gorgeous OLED display that provides a variety of important information, including the input source, its sampling frequency, volume, and the name of the SOUND FIELD mode used—all in an exceptionally easy-to-read manner. The display automatically turns off after being operated, eliminating any distractions or slight undesirable effects on the sound.
