Naim 555DR PS-2020

Naim 555 DR PS power supply, this one shipped to us from Naim in July 2020.  It’s had one owner from new. This has the reference (brushed black anodised aluminium sleeves that matches other 500 series components)

We’ve carefully listened to this against a 2024 ‘white logo’ 555 DR PS and can say with confidence that this is in very fine sonic fettle. Happy to demonstrate.

Serial number 473956

Naim 555DR PS-2020 is supplied in the original packaging with ‘Powerline’ Naim mains lead, manual and, well, that’s it! The relevant burndy leads come with the source component. Free UK Mainland delivery.

Our 12 month warranty applies.

555DR is a requirement for ND 555 and CD555 and a fantastic upgrade for NDX2, NAC-N 272 as well as NDS, CDX2, CDS3 etc. For these non-555 units, you need to factor in an XPS burndy too.

New price was £8499

It provides a smooth, stable, and low-noise foundation, which significantly enhances your listening experience when paired with any Naim Audio product. You’ll be amazed at how your favorite songs and artists come to life with greater clarity, naturalness, and precision. This power supply will change your listening experience by delivering a higher dynamic range and immersing you in the music like never before.

TECHNOLOGY & CRAFT

The 555 PS complements the CD555 CD player but can also be used with other devices like ND 555, NDS, NDX, NDX 2 network players, HDX hard disk player/server, DAC digital-to-analog converter, and CDX2 CD player.

The 555 PS delivers superior sound quality. It has a powerful transformer with five separate windings that output to seven regulated supply voltages, including one for our CD555’s clock circuitry. Improvements have been made to the wire routing, mechanical decoupling, and internal layout of the new Naim Audio DR. These enhancements have significantly improved performance and make music even more enjoyable.
