GRAHAM SLEE - REVELATION PHONO PREAMP

The Graham Slee Revelation – Breathe New Life into Your Record Collection!

The Graham Slee Revelation phono stage preamp is based on the highly successful Era Gold Reflex phono stage preamp, positively reviewed by Michael Fremer in September 2007's Stereophile magazine and was awarded recommended system component in the October edition, listed as a "Class A" recommended component along with the much coveted triple dollar value-for-money sign.

The Revelation is supremely versatile and sounds incredibly good!
The Revelation 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 experimentation. 

Design Features:
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 impedances. 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 impedances 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.

The Revelation's cartridge sensitivity and gain is fixed for Moving Magnet or High Output Moving Coil pick-up cartridges and the input impedance is 47k Ohms. For use with low output Moving Coil pick-ups, the Elevator EXP head amplifier should be used ahead of the Revelation. These stages are designed to work together to give an unsurpassed moving coil performance for their price-bands and far beyond.

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.
