HEADPHONE AMPLIFIER / PREAMPLIFIER / DAC
Our headphone amplifiers HD100-HD120 are equipped with a converter stage to allow you to play digital sources. All our development has been carried out around a selection of the best headphones on the market to guarantee you great versatility and flawless musicality. The HD100 and HD120 models are equipped with a preamp output so that they can be combined with MA100 or any other ATOLL power amplifier.

“(…) 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. Also featuring two inputs analogue outputs and a line output with variable level, it can also be used as a preamplifier, offering the same very good performance. our Qobuzissime reward.”
