INTRODUCTION, FEATURES AND TECHNOLOGY
Thank you for purchasing the Brio-
R
the latest version of Rega’s best
selling amplifier.
Housed in a brand new case the Brio-
R
draws on the pedigree of the
previous three incarnations of this model. The sonic recipe for the Brio
embodies the best in traditional audio circuits with excellent engineering
practice.
A newly designed output amplifier in the Brio-
R
was born after extensive
research by our engineers to develop a low source impedance emitter follower
Class A driver stage. This is based around a complementary pair of 150w
Sanken Darlington output transistors. The technical and sonic improvement
gained by the use of low impedance drivers is well known, however it can
feature high standing currents in the driver stage when using standard
transistor configurations. By combining the low impedance driver with the
Sanken Darlington transistors (with their imbedded thermal bias network
running at a lower standing current) this combination forms a complementary
emitter follower emulating Class A conditions with good thermal stability with
lower standing currents in the driver stage.
