Even though the Jazz Club 78/RIAA Equalizer has been superseded by our Revelation M 78/RIAA Equalizer, the original Jazz Club has all the properties of the miraculous Era Gold V MM phono stage and offers a lower cost way of enjoying nearly 100 years of discs.

Its generous selection of preset equalisation curves make it possible to play old 78s, 1940's LPs and EPs the way they were intended to sound. A modern phono preamp only equalises RIAA standard records — those recorded since the mid-fifties. The Jazz Club does RIAA and a whole host of pre-standardization EQs too — click the review tabs to discover how well your old records can sound. There's also a graphical guide here (click to view) of many of the equalisation curves and the record labels and years to which they apply.

Media Reviews

"Even my earliest LP, a 1949 American Decca pressing of Oklahoma leapt to life in an energising manner that defied its years... Louis Armstrong's 1933 St. Louis Blues [78] had an in-the-room vividness that was at times startling.

[Tony Bolton, Graham Slee Jazz Club, Hi-Fi News, June 2006]

"Here I was able to compare another of those classic D'Oyly Carte recordings - the 1950 set of The Gondoliers (LK 4015-6) - with the recent Naxos Historical CD reissue of the same sessions, and the results were certainly illuminating.

[Caroline Osborn, Graham Slee Projects Jazz Club, Gramophone, March 2003]

"I couldn't believe the presence of Ella's voice, or the lack of noise from the old shellac.
