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

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

Of course, the Crosby can be connected to any preamplifier, not just the Tosh: for example, it is perfectly at home connected to the Young MkIV if the latter is used in the dual function of D/A converter and preamplifier.

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

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