Descripción
Our HD100 and HD120 models stand out with their unique converter stage, enabling you to enjoy digital sources. We’ve meticulously developed these models around the finest headphones, ensuring exceptional versatility and flawless musicality. Notably, both models feature a preamp output that can be seamlessly combined with MA100 or any other ATOLL power amplifier.
- 4 mm brushed aluminium front.
- 3 independent linear transformers (including
- 2 very low noise reserved for analogue audio in dual mono configuration).
- 8 regulated power supplies (including 4 specifics for the audio stages).
- Analogue volume control (ALPS potentiometer).
- Class A biased discrete component audio preamp stages.
- Final stage with bipolar transistors.
- High-end CLARITY CAP MKP Link Capacitors.
- BURR-BROWN PCM5102 converter:
– Dynamic: 112 dB.
– Signal/Noise ratio: 112 dB. - Optional remote control (volume management and selection).

FOR INFORMATION
The HD100 has a single amplifier, but its power can accommodate two headphones in parallel. In addition, its output impedance is low enough to broadly support two headphones without affecting musicality.
Optional remote control (allowing to control all products: Integrated, CD Players, Tuner, DAC).
“(…) In conclusion, the headphone amplifier with USB S/PDIF Atoll HD100 DAC offers excellent sound results where a sense of detail, sound balance and respect for dynamics combine happily. It also features two inputs, analogue outputs and a line output with variable levels. It can also be used as a preamplifier, offering the same excellent performance. our Qobuzissime reward.”
