CD/SACD-проигрыватели и транспорты — Yamaha CD-C603

The Yamaha CD-C603 is a five-disc CD changer with a front-panel USB port, aimed at listeners who still keep a physical CD library but also store music files on USB memory. In the United States it carries a list price of USD 699.95 and comes with a two-year manufacturer warranty. The black finish is designated CD-C603BL, and a remote handset ships with it. The same unit is sold as the CD-C603RK in the Asia and Oceania region.

Key specs that matter

Measured on CD, the player achieves 105 dB signal to noise, a dynamic range of 96 dB and harmonic distortion of 0.003 percent. Frequency response on CD runs from 2 Hz to 20 kHz. For data discs and USB files, response is 2 Hz to 22 kHz at a 48 kHz sampling rate and 2 Hz to 44 kHz (-3 dB) at 96 kHz. Compatible disc types are pressed CDs, CD-R blanks and CD-RW, and file formats are MP3, WMA, AAC, WAV and FLAC up to 96 kHz and 24 bit. On the back panel there is a single stereo pair of unbalanced RCA analogue sockets next to one optical digital socket, and a 3.5 mm remote input and output pair allows wired control links. Its chassis measures 435 x 116 x 405 mm, with a weight of about 5.6 kg.

Engineering and use context

The tray opens fully, so all five discs can be loaded or exchanged in one step. PlayXChange takes this further by letting the owner swap four discs while the fifth continues to play, which keeps playback running during a library change. Yamaha describes the signal path as short, with refined circuitry, an intelligent digital servo and a floating mechanism for the laser pickup that isolates it from external vibration. Pure Direct mode, the same function found on Yamaha amplifiers and receivers, is available from a front-panel button or from the remote and is intended to keep noise interference to the minimum. Among the file types, MP3, WMA and AAC are compressed formats, while WAV and FLAC are lossless, and the high-resolution ceiling covers many high-resolution downloads. The USB socket sits on the fascia, so a stick with FLAC or WAV files can be plugged in without reaching behind the rack.

Pairing

Any line-level input on a stereo amplifier or receiver accepts the RCA analogue signal, while the optical jack lets an external DAC or a receiver with its own converter take over digital decoding.

Alternatives

The Yamaha CD-S303 is a single-disc player from the same brand with a front USB input and a 192 kHz/24-bit DAC.
