Stereo power amplifier

Highest quality power in a small size

The Crosby is a versatile high-efficiency Class D stereo power amplifier that constitutes
the perfect complement to the Tosh preamp, both in format and sound.

Its power is sufficient to effectively and cleanly drive most loudspeakers, while its power delivery capability can be greatly increased by configuring it in Bridge mode.
In this case, the Crosby becomes a powerful mono amplifier; two bridge-configured Crosbys can drive virtually
any loudspeaker, be it a dynamic driver array or an electrostatic panel.

Naturally, the Crosby can be connected to any preamplifier, not just the Tosh: for example, it is perfectly at ease connected to the Young MkIV, when using the latter in the dual function of D/A converter and preamplifier.

It features both single-ended and balanced inputs, plus it features a trigger input to allow it to be turned on automatically by the preamplifier.

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


The Crosby expresses from the outset the high efficiency and relaxed power typical of class D, which allows it to drive most loudspeakers with ease and without apparent failures....
Crosby, Young, Gifted and, er, not Black…John Scott hangs out with M2Tech’s Rockstar separates and finds himself helpless to resist their charms....
The first impression you get from this set is the modesty, simplicity and good taste of its design....

The Crosby offers the best together with…
