MA 600

High-end hybrid integrated amplifier with tube preamplifier and semiconductor output stage

Power & Performance! While the low-noise tube preamplifier used by the high-end hybrid integrated amplifier ensures an audiophile and natural sound, the discrete semiconductor output stage delivers maximum power and performance. Powerful, flexible & authentic – the MA 600.

High-end hybrid integrated amplifier with tube preamplifier and semiconductor output stage

The high-end hybrid integrated amplifier combines a maximum output capacity with an audiophile acoustic performance. The discrete semiconductor output stage lets its full potential unfold with up to 70 watts of power per channel. The elaborate power supply unit with its stabilised voltage for individual circuits and the generously-dimensioned toroidal transformer ensure a clean and stable power supply. The low-noise tube preamplifier is largely responsible for the audiophile, harmonious and natural sound. The preselected ECC 88 tube has been burned-in for 60 hours to ensure maximum signal stability in the high quality tube socket. Flexible and high quality audio enjoyment is ensured thanks to the analogue & digital inputs, which include a USB port with 192 kHz / 24 bit support, as well as Bluetooth and aptX compatibility. The stringently selected components used for the MA 600 are accommodated in an exquisitely processed housing that features a 5 mm thick front panel and solid aluminium controls.
