This is the highly acclaimed amplifier from the M2Tech Rockstars series.

The Crosby is a versatile high efficiency class-D stereo power amplifier which does for a perfect pair with the Young MkIV, both in size and sound.

Its clean power is enough for most speakers, while its drive capability can be improved by setting it in bridge mode. In this case, the Crosby becomes a powerful mono amplifier; two Crosby in bridge mode can drive virtually every speaker, be it an array of dynamic drivers or an electrostatic panel.

Of course, the Crosby can be attached to every preamplifier, not only to the Young MkIV. It is provided with both single-ended and balanced inputs, plus trigger input/pass-through.

Thanks to its class-D design, it is virtually impossible to destroy, all overload situations are reported on the front panel.
