NN Ultra X MK2 Mains Purifier

The Fidelty Audio NN Ultra X MK2 Mains Purifier has 6X more noise filtering than the NNU SE housed in a custom case with EMI / RFI shielding. The NN Ultra X MK2 Mains Purifier gives even greater 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.

Hi Brent,

Thanks for the efficient processing of my upgrade. Going from a No Noise x to Pro fitted with HF filter made me wonder how much more I’d get from this upgrade (NNUX REF). I am now not far off full burn in time, again the journey varies with immediate improvement with clarity which towards the end, once burnt in the bass tightens up nicely with a fantastic soundstage. I think the HF filter adds to the emphasis of transients (leading edges). The pro is used also with balanced mains, which might sound like overkill but the Pro makes a superb difference in it’s own right.

This upgrade is well worth the money. It is probably not too dissimilar to the New Pro reference, but I suspect that with the improved capacitors, Furutech socket and Kimber wiring in the Reference you will squeeze even more out of your system knowing Brent’s engineering skills!! Invest your money wisely, rather than get something less capable from other Mains Product companies.

Thanks Brent

Hi Brent,

Just to let you know, I’ve had great results with the Fidelty Audio NN Ultra X Pro Mains Purifier (now called NNU X). I now have my full soundstage back and don’t have to sit up until 2am to hear my system at its best (though I probably will)! As well as fixing my wonky soundstage, I’ve also noticed how much tighter the bass sounds. All round a great improvement and probably the best value for money hi fi investment I’ve ever made!

Many thanks,

Graham

With this newly upgraded filter there is a noticeable difference in the lack of background interference music is now less mushy and a lot clearer since it has had time to run in. Only after listening to this did I realise the difference that could be made by upgrading

Thanks for all upgrades Brent

Hi Brent, I just thought I would let you know how im getting on with ultra x. I plugged it in the moment it was delivered and instantly I could tell the diffence. After a week of constantly running the systems dynamics have been taken to whole new level. The detail and dynamics are just out of this world, the music has far more emotion and the sound stage just opens up!. If any one is thinking of buying one don’t wait your missing out so much!!!!. The best £375 ive ever spent!
