NN Ultra X SE Mains Purifier

The NEW Fidelity Audio NN Ultra X SE is designed as a All-in-One filter and sits half way between the NNUX MK2 and the NNUX HF (when used together).

The Fidelty Audio NNUX SE Mains Purifier has 3X more noise filtering than the NNU SE + the benefit of a large HF filter with 16 filter points housed in a custom case.

The NN Ultra X SE Mains Purifier gives great mains noise reduction, allowing you hear an impressively natural sound, with much greater dynamics and bass extension. On top of this there is much less harsh sibilance.
