CD555 CD Player


CD555 CD Player

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 Audio products, its power supply components are housed in an entirely separate unit, the 555 PS, for ultimate performance.

"We introduce what could be the Porsche Carrera of players"
Hi-Fi World, Dec 2005
"the CD555 doesn't try to play DVDs, DVDs As, or SACDs. It doesn't have a digital output. The CD555 just plays CDs and that it excels".
