SPL Phonitor One d
The SPL Phonitor One d is an audiophile headphone amplifier with an innovative Phonitor Matrix, 32-bit DA converter and outstanding sound quality. The technically sophisticated headphone amplifier manages the balancing act between increased power and high level without losing its detailed sound quality. In contrast to the Phonitor One, digital sources can also be connected to the Phonitor One d. Thanks to the 32-bit DA converter, the Phonitor One d qualifies for the currently highest-resolution audio Playback.
