The design of this booster amplifier is Unison Research’s direct response to those who insist that in order to have major power in tube amplifiers, it is necessary to resort to more expensive devices that are far bulkier and heavier. The U Power makes it possible to use a tube amplifier of limited power while obtaining adequate volume levels in larger environments. The U Power is ideal for those listeners who want to keep the sonic strengths of their low-powered tube amplifiers while experimenting with relatively inefficient loudspeakers.
