Graham Slee Revelation M and C phono stages

Both Revelation phono stage preamps are identical to the original Revelation phono stage preamp with the exception that the Revelation M is for moving magnet cartridge sensitivity, and the Revelation C is for moving coil.

Revelation M phono stage preamp: for moving magnet, high output moving iron and high output moving coil cartridges.

Revelation C phono stage preamp: for conventional (low) output moving coil cartridges.
They are switchable-equalisation-curve versions of the Reflex M and Reflex C phono stage preamps.

"...the musical delivery steps up several levels - to the extent that with certain records it starts to challenge the musical virtues (as opposed to the sonic qualities) of the more expensive units here."
[Roy Gregory, Graham Slee Revelation, Hi-Fi +, May 2008]

The Revelation phono stage preamps build on the sonic strengths of the earlier Jazz Club phono stage preamp.

The different equalisation (EQ) curves for non-RIAA records are explained in "From 78rpm through to RIAA equalization" (click link). The different curves are selected on a switch-matrix on the front panel. When switched to RIAA for all modern (post 1954) records, the Revelation shares the same performance of its Reflex stable mate.

Like its Jazz Club predecessor the Revelation also "rides" the clicks, reducing surface noise through higher propagation speeds. Apart from badly worn or damaged records, surface noise is relegated to a position well behind the music...

"The Jazz Club is also accomplished in this respect, but the Revelation moved the performance up a few notches, with records sounding noticeably cleaner."
[Tony Bolton, Graham Slee Revelation, Hi-Fi World, May 2008]

Power Supply

Also available with PSU 1

Today's domestic electricity supply can prove problematic for the committed audiophile; voltage variations and spiking within the AC supply can seriously detract from the listening experience
For those customers who do not intend to rewire their house, or spend small fortunes on miracle block/cables, the Graham Slee Projects PSU1 power supply is now available.

Designed for use with all Graham Slee phono stages, the PSU1 comes as standard with the Era Gold, Jazz Club, Elevator EXP and Solo Headphone amplifier; and can be purchased separately as an upgrade for the Gram Amp 2, Gram Amp 2 SE and the Intro models of the Solo and Era Gold.
