The d1-CD is a CD transport from TotalDAC, a French manufacturer, built specifically to feed an external DAC rather than convert digital signal to analogue itself. Positioned by TotalDAC as the ultimate solution for high-end disc-based systems, the d1-CD inherits every piece of research the brand developed for its DACs, reclockers and streamers, applied here purely to the mechanical and clocking side of disc playback.
Key specs that matter
Two digital outputs are provided - coaxial RCA S/PDIF and XLR AES-EBU, though the manufacturer specifically advises against using both simultaneously. The transport outputs a 100% original Red Book signal at pure 44.1kHz/16-bit without any modification whatsoever, and can also read the CD layer of a hybrid SACD disc. The top-loading mechanism uses the modern Austrian CD-PRO8 drive from SUOS-Hifi, founded in 2006 by former Philips CD engineers. The oscillator achieves an exceptionally low 40 femtosecond RMS jitter figure, an unusual specification that TotalDAC credits directly for the transport's impression of instant dynamics. A separate live-power external power supply offers considerably better galvanic isolation than conventional mains supplies, emitting no mechanical vibration or electromagnetic interference near the transport mechanics, digital signals or oscillator. The drive mechanism sits on a solid copper plate serving as mechanical ground reference - identical to the approach used in TotalDAC's own DACs - decoupled from the playback mechanics by four conical springs and four silicone rubber dampers, itself isolated from the equipment rack by three anti-vibration feet with integrated ball bearings, with a carbon intermediate plate and cover further damped by ferrite rubber. CD-text functionality is supported. Power consumption is 10W while playing a CD. At 135 x 360 x 290mm and 8kg, the aluminium and PMMA enclosure is available with an optional silver massive aluminium front panel, 110V/120V 60Hz power option, or BNC coaxial output in place of RCA.
Sound and use context
Expect an immediate enhancement in the quantity of information conveyed compared with conventional CD transports, with an engaging, lifelike character linked to the exceptionally low jitter figure.
Pairing
The d1-CD is specifically designed to feed a TotalDAC DAC or any other external converter, and pairing it with TotalDAC's own d1-streamer-live and matching DAC creates a coherently engineered, fully TotalDAC digital front end.
Alternatives
TotalDAC's d1-streamer-live sits alongside this transport as the brand's network-streaming counterpart, sharing the same reclocking philosophy for buyers wanting network playback rather than physical disc spinning, worth pairing together or choosing between depending on a specific listener's source material preferences.
