Revelation - Archival Phono Preamplifiers
Old & New Record EQ—Made Easy!

There's a model for high output cartridges - the Revelation M; and a model for low output moving coil - the Revelation C.
The Revelation M is available with either the basic ("green energy") power supply or the PSU1 power supply for improved sonics. The Revelation C is supplied with the PSU1 power supply only. Both models are fitted as standard with a rear panel mono-switch.

Pre-set Equalisation for Repeatable Results
Our research into the equalisation required for numerous old record labels makes it easy for you to select the most suitable tonal balance time after time.
Being arranged as presets on front panel switches, the guesswork of variable controls is taken away, leading to repeatable results.
The different EQ settings will allow you to obtain a good tonal match to what the the original sound would have been on 78 rpm records, vinyl LPs and EPs
There is also an RIAA setting for modern stereo vinyl records, which makes it a significant stereo RIAA preamplifier.
The Revelations are suitable for professional archiving use as well as private use where you want the option to play and archive records from different eras.
Revelation M
The Revelation M stereo RIAA stage is for high output cartridges of the moving magnet, high output moving coil and high output moving iron varieties.
Based on the Reflex M hi-fi RIAA preamp, it is optimised for these high output cartridges - its input stage having more than adequate dynamic headroom to be able to accept the largest signal peaks.
By "dynamic" we mean it can handle peaks without slew-induced distortion, and transients whether musical or due to surface imperfections, do not get "slew-distorted". This is an important factor which means archival copies will retain more of the original detail with fewer distortion artifacts.
Revelation C
The Revelation C was designed for archivists with a preference for low-output moving coil cartridges, and is based on the Reflex C hi-fi RIAA stage moving coil phono preamp.
Power Supplies
For best results we recommend you choose the PSU1 power supply option for the Revelation M. It is otherwise available with the basic power supply which is low-energy and is suitable where equipment has to comply with low-carbon targets. The Revelation C is only supplied with the PSU1.

Reviews
With the final Depeche Mode track, the Revelation’s abilities make for a superb performance too. The speed and attack coupled with the bass response result in a powerful performance and there is an appealing tonal darkness to the upper registers that complements the nature of the music extremely well. The slight congestion that is present in the upper midrange is handled well and the emotional content to the vocals is delivered very effectively.
WE SAY: A talented and very clever phono stage that delivers excellent sound quality.-
Read the complete Hi-Fi Choice review, May 2018
In short, it’s a phono stage that’s as easy to shell out the ducats for as it is to enjoy. Add the immense improvement in sheer musicality that can come from judiciously using those selectable EQ curves, and it’s a no-brainer. Perhaps that’s the Revelation M’s most defining quality: Its ability to consistently deliver musical joy, record after record, night after night, RIAA LP or otherwise. If getting the most musical and sonic goodness from your cherished LPs (or shellacs!) without breaking the bank is important to you, give a listen to the Revelation M. You just might fall in love with it, as I did. And maybe you’ll buy one -- as I did.
- Oliver Amnuayphol, Soundstage Network, February 2014
Running the [Revelation plus Elevator] as a straight RIAA stage and optimizing the front-end loading, the performance is more than impressive for the price. But as soon as you start using the EQ facilities on the MM stage, 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. The Previn/LSO Rachmaninov 2nd Symphony, a 1972 EMI recording is a good example of this. A wonderfully lyrical reading, this is an early pressing of an otherwise unremarkable record you might easily pick up in a charity shop/thrift store, or at a bottom dollar price from a specialist secondhand dealer. Played via the RIAA only Groove and Herron stages it’s a nice but rather run-of-the-mill outing, a shade stilted and constrained. It sounds much the same via the Rev/El when it’s set to RIAA EQ. But switch it to the preferred setting for EMI recordings and the transformation is astonishing. Suddenly it becomes sumptuously fluid and powerful, graceful and sweeping; suddenly it has you wanting to conduct the orchestra, a sure sign that it has taken on a new level of musical involvement but also that there’s a natural weight and momentum at work.

...I was pleased with the easy-going, not noisy way that the Revelation seemed handle any music....it's true that many of these recordings rise to another level when correctly equalized, weird things disappear and the original tonal balance all of a sudden makes much more sense. It is then when multi-EQ phono stages such as Graham Slee Revelation M become highly valuable.
