NAD C546BEE CD player titanium

This product is no longer available for sale!

Overview

Many enthusiasts enjoy creating compilations on CD-R/RW discs. The C 546BEE can read CD-R/RW discs and decode MP3 and WMA files, offering the ability to store up to 10 hours of music on a single disc, or even more via the front-panel USB Host port.

Not all digital outputs are of the same quality. Particular attention has been paid to those of the C 546BEE, due to the increasingly frequent use of a digital connection with other devices. The coaxial output benefits from a buffer stage and a transformer to isolate it from the converter, and the output impedance has been carefully adjusted to represent exactly 75 Ω. This attention to small details reduces clock errors (jitter) that disrupt the digital stream.

The analog and digital sections are carefully isolated to avoid any interference, using specific regulators for the power supply and a highly studied circuit design. The 24-bit Wolfson converter was chosen for its excellent linearity at low levels. Polypropylene capacitors and metal film resistors have been selected to ensure an accurate frequency response. Burr Brown OPA5532 op-amps and a low impedance output to reduce the influence of cables complete this choice of excellence.

User reviews

Jean Claude

Overall, it's a good player but curiously, it gives a strange impression on certain CDs. It is not moving in musical expression. Its quality remains the precision of instrument rendering and a coherent placement. On the other hand, the mechanics used for this player are a bit "cheap", the electronics are decent but nothing more.

Pros: good reading precision with substance.
Cons: restricted stereo image and gives a boring impression on certain CDs.

C'est un bon lecteur dans l'ensemble mais curieusement, donne une impression étrange sur certain cd. Il n'est pas émouvant dans l'expression musicale. Sa qualité reste la précision du rendu des instruments et un placement cohérent. Par contre, la mécanique utilisée pour ce lecteur est un peu "cheap", l'electronique est digne mais sans plus.

Les plus : bonne précision de lecture avec de la matière.
Les moins : image stéréo restreinte et donne une impression ennuyeuse sur certain cd.

This CD player offers a clear and precise sound that is very pleasant to listen to with good dynamics. The convenient USB port on the front, which provides the same musical quality as the CD, allows for organizing music by folder. The finish is very neat and understated with simple and intuitive functionality.

Pros: very good product and value for money.
