First shown and demonstrated at The Hi-fi and Home Entertainment Show at Heathrow in September 2005, Naim's reference CD player, the CD555 with 555 PS delivers the ultimate musical performance from a CD.

The CD555 makes no attempt to play DVDs, DVD-As or SACDs. It does not have a digital output. Nor does it have a variable output. The CD555 simply plays CDs and at that it excels. We are confident that it is the best CD player ever.

Does not include 555PS Power Supply


The CD555 is our reference CD player, the finest we have ever made. It’s a statement of our engineering excellence, a showcase for our core beliefs. Of course, it’s a fast, detailed and dynamic-sounding performer: anything less would be fundamentally at odds with who we are and what we do. But more than any one particular aspect of its presentation, the CD555’s genius is the way it brings each disparate strand of your music together into one fluid, natural and involving performance. This, we believe, is how hi-fi should sound.

Technology & Craft

Zero-compromise quality demands single-minded engineering. The CD555 ignores those disc formats you don’t need. It avoids features that don’t contribute to its performance. It represents not a radical step into the unknown, but the ultimate expression of everything we’ve learned. So it uses a top-loading transport mechanism and a heavyweight brass sub-chassis which suspends critical electronics away from microphonic interference. A carefully designed, low-resonance CD clamp avoids the vibration-induced errors that afflict conventional CD mechanisms while its digital-to-analogue converter circuitry is shielded by a dedicated enclosure, ensuring superior isolation from electric and magnetic fields.

Wiring alone takes six hours of dedicated craftsmanship, while many of the CD555’s components are hand-selected to ensure that only the very best of each type make their way into each player. And as with many Naim products, its power supply components are housed in an entirely separate unit, the 555 PS, for ultimate performance.


    Massive aluminium chassis to minimise resonance and vibration
    Critical electronics suspended on a brass sub chassis via coil springs
    Low-resonance CD clamping system using rare-earth magnetic puck
    Non-reflective coatings used around the CD mechanism to reduce interference and noise
    Shielded enclosure to isolate DACs, plus separate low-jitter clock circuit with its own power supply
    Separate high-performance power supply (555 PS) to isolate sensitive electronics from electromagnetic interference
    Hand-built from carefully selected components
