Product Overview

Supplied with the PSU1 Power Supply

Graham Slee top line phono pre amp the Revelation, features for the first time both balanced and single ended outputs. As with the Jazz Club/Era Gold phono stages the Revelation shares a circuit with its simpler brethren, the Reflex. The other all new phono stage that is setting a new standard in vinyl replay. The only difference being its multi EQ functionality.

With a selection of 15 different equalization characteristics, the Revelation will reproduce the sound from virtually any historical or contemporary recording, with skin tingling nostalgia. People may ask why do you need these, well a quick look at Grahams web site at the multitude of EQ curves, used by recording engineers to cut the blanks when starting the vinyl chain, makes you realise not all records are recorded the same. In fact pre RIAA and for many years after its inception, recording sound completely different to that intended unless the correct equalisation is applied on playback.

    Astonishing Value

    Posted by Bob Parsons on 25th Mar 2015

    I will start by saying that I didn't buy this item from British Audio Products as it was part of a package from another supplier, but I have bought from BAP and will again. The Revelation M (in my case) driven by Len Gregory's Musicmaster cartridge punches way above its price. It is valve-like (in a good way): it has wide bandwidth: it has quite startling dynamics and it is the nearest thing to real music I have ever heard inan audio system. It is that great rarity, a very musical detail hound, and it represents astonishing value for money. Those very expensive Zanden 'stages had better be VERY good if they are going to show a marked improvement over this little guy. I love it!
