The DA30 typically uses four EL34 or KT88 power tubes (depending on the revision) and three 12AX7/ECC83 small-signal tubes. It features a moving magnet phono stage on early models, four line-level inputs, and a stunning gold-anodized front panel with large VU meters.

The Jadis DA30 is a high-end, pure Class A stereo tube amplifier utilizing a push-pull configuration. Known for its "golden grille" aesthetic and lush harmonic texture, the manual emphasizes critical safety protocols for high-voltage operation, specific biasing procedures for the output tubes (EL34), and a mandatory loudspeaker impedance matching process.
