M2TECH ROCK STAR SERIES :
Marley MkII Headphone Amplifier
The Marley MkII is a High performance Headphone Amplifier with literally all you need
for a first-class Headphone (& Preamp) listening experience.
"1st Review" now available - it's a bit Googly but you'll get the gist :
With its discrete componentry, low-noise design with FET input it delivers crystal-clear power to every kind of Headphone.
The totally silent background, even with the most sensitive Headphones, is granted by an ultra-low noise dual regulator.
Up to 10Vrms max output voltage (20Vrms at the Balanced output) allows every Headphone model to generate optimum sound.
Marley MkII is very versatile - apart from accepting both Single-Ended and Balanced Sources, it is accompanied by a 3-band Tone control - allowing users to tailor frequency response to their ear and taste. The Tone control can of course be disabled.
In addition, older Stereo recordings (affected by the so-called 'ping pong effect' caused by excessive channel separation), can be enhanced by enabling the cross-feed circuit.
A perfect match therefore for all types of Headphones ... as you are also able to select the output impedance between Low-Z, 10 OHms and 47 Ohms to cover various designs.
A Tape output and Preamp output (doubling the Single-Ended output on RCA connectors on the rear panel) also allow you to use the Marley MkII as a true Preamplifier.
The Marley MkII can be operated by both the front panel controls, or the IR Remote and with an app (available for both iOS and Android) via Bluetooth Low Energy.
As with all products within the Rockstar range ... upgrade is possible with the addition of the 'Van der Graaf' PSU.
Price : $3,595 - AU Enthusiasts NZ $3,175 incl. freight.
