Graham Slee Revelation Phono Preamp
Breathe New Life into Your Record Collection
The phono-stage preamp provides the correct EQ for
virtually every phonograph record ever made, with 7 equalization
networks which combine using three 3-way front panel switches to equalize up to 15 different recording curves
- 12 of these settings will equalize known record label recording
curves including the modern-day RIAA - the other 3 are for
The Revelation uses many similarly selected components from branded specialist high-quality audio component manufacturers as the Jazz Club. These components are selected on real technical merit, and the difference they make, on listening, is obvious.
The Revelation differs from the Jazz Club phono stage in its internal grounding method as well as its equalization network impedance. The grounding method used in the Revelation has been further optimized to lower the noise floor even more, allowing the Revelation to
extract even more subtle detail and background cues, taking the
listening experience another step closer to reality, whatever the
music's genre. The Revelation's EQ network impedance have been
raised a bit to further exploit the ultra-high slew rate of its
amplifier stage. This combination of improvements make the Revelation phono stage, and the Reflex on which it is based, the ultimate in "live sounding" phono stages.
Like all Graham Slee wideband designs, best performance is
obtained by the unit being powered continuously, and a period of
"burn-in" (approximately 3 weeks) should be observed for its components
to fully form and stabilize. To ensure proper continuous correct
operation, the Revelation phono stage is supplied with the IEC approved PSU1 in-line power supply unit.
A mono switch is included on the rear panel to conveniently
use a stereo pick-up for mono work. For exacting mono work a mono
pick-up should be used in stereo mode and the unused input shorted. It
is not advisable to convert stereo recordings to mono using a mono
switch as the summing function puts emphasis on center channel signals.
