Norma Audio Electronics Revo IPA-140

A shortcoming in the previous iterations of the Revo IPA-140 still holds, but not to the same extent. Although the amplifier features a balanced input, the Norma integrated is best used in single-ended operation. The balanced input should no longer be considered ‘vestigial’ or something to be avoided at all costs, and the Revo IPA-140 now deals with XLR as a reasonable analogue audio pathway, but if you can go single-ended, do so. XLR offers no advantages over single-ended with the Revo IPA-140.

The audio industry is broadly divided into two main camps; ‘change for change’s sake’ companies that revise every product in their line-ups on a regular basis, and ‘if it ain’t broke, don’t fix it’ brands who keep their products developmentally frozen for years. Norma is one of the rare exceptions, that keeps making ever better products, but doesn’t shout about it. Looking back on our review from 90 issues ago, Norma didn’t reinvent the wheel here and the sound of the Revo IPA-140 is tonally unchanged, but it builds on its strengths and strips back on its few vices still further. In other words, it’s every bit as damn good as it ever was; “if it ain’t broke, make it better!” This integrated amplifier is one of the audio world’s best-kept secrets.
