Marley is a very high performance headphones amplifier conceived to give best sound
quality with every kind of headphones, from small in-ear models to expensive and
challenging planar transducers devices. Its pure Class-A, discrete components amplifiers
deliver crystal-clear sound at any level up to 8Vrms in single-ended mode (that is,
driving headphones provided with standard 6.35mm jack) or 16Vrms in balanced mode (that is, driving
headphones provided with 4-pin XLR jack).
Two stereo amplifiers are fitted into the Marley, each one with its volume control. This
way, two headphones can be driven in single-ended mode to allow two listeners to enjoy
their music at their favourite listening level.
On the other hand, purist audiophiles using headphones with balanced drive capability
can set the Marley in balanced mode, obtaining 6dB more SPL and improved sound
Marley is provided with a 15V-30VA wall adaptor. An input for an external high-current,
low-noise power supply is also present on the rear panel.
