xDuoo

xDuoo occupies an unusual niche: portable and desktop amplification with a taste for tube hybrids. If you want a little warmth and texture in the signal path rather than the last decimal of measured accuracy, this is the catalogue to browse.

The portable DAC/amps carry serious power for their size, and the desktop line includes hybrid designs that let you roll tubes — an inexpensive way to tune the character of an entire system.
