REFERENCE PRE

Tube Preamplifier * Dual Mono * 3 Integral Chassy
Many Unison Research customers have expressed the wish for an all-tube pure class-A power amplifier with a power output significantly higher than any previous Unison product. In order to satisfy this request, the Unison Research design team has created a single-ended monoblock amplifier able to deliver 80 watts in pure Class-A. This product has become the first in a new line which embodies all our experience in valve amplifier design acquired over the years–the Reference Series.

Having completed the power amplifier project, a preamplifier of similar quality and performance was added, and it is fully worthy of inclusion in the Reference Series. We have named it, of course, the Reference PRE.
