Luxury Precision AD1955 audio board

E7 AD1955 DAC Board
Classic Hi-End sound, reimagined for portable audio.

Featuring dual ADI AD1955 chips, this is the first time the legendary DAC has been applied to a portable player. Known for its refined tonality, smooth textures, and rich musicality, the AD1955 brings a uniquely elegant character to the E7—clear yet emotional, detailed yet natural.

This new board doesn’t just sound different—it’s built different:

• Fully powered single-ended output matches balanced performance, offering uncompromised dynamics through any headphone port.
• EA4-optimized Line Out delivers exceptional synergy for stack setups.
• A discrete bias compensation circuit ensures tonal consistency, adapting intelligently to different playback settings while preserving the signature AD1955 sound.

Designed with audiophiles in mind, this upgrade card transforms the E7 into a portable expression of classic Hi-End spirit—sophisticated, musical, and unmistakably distinctive.
