首页 HiFi百科 选购指南 CD Player as Transport + External DAC: Is the Upgrade Worth It?
快速回答

Using a CD player's digital output (coaxial/optical) to bypass its built-in DAC and feed an external DAC is the most cost-effective way to achieve flagship CD sound. Three budget scenarios: Entry: Yamaha CD-S303 ($310) + TRASAM LP3 ($390) = $700 for a complete CD transport + DAC system. Mid-range: Marantz CD6007 ($490) + TRASAM DS7PLUS ($840) = $1,330 — DS7PLUS provides 18dB more dynamic range than CD6007's built-in AK4490. Flagship: Cambridge CXC V2 ($770 pure transport) + TRASAM DS8 ($1,540) = $2,310 — rivals $4,000+ flagship integrated CD players.

CD Player as Transport: The Cost-Effective Upgrade Path

Most CD players split their cost between the transport mechanism and built-in DAC. If you bypass the built-in DAC and use a high-quality external DAC via digital output, you achieve near-flagship CD sound at a fraction of the cost of a flagship integrated CD player.

3 CD Transport + DAC Builds

Budget CD Transport External DAC Total Performance
Entry Yamaha CD-S303 ($310) TRASAM LP3 ($390) $700 Beats any sub-$1,000 integrated CD player
Mid-Range Marantz CD6007 ($490) TRASAM DS7PLUS ($840) $1,330 Rivals $2,000+ integrated CD players
Flagship Cambridge CXC V2 ($770, pure transport) TRASAM DS8 ($1,540) $2,310 Rivals $4,000+ flagship CD players

How to Connect

  1. CD player digital output (coaxial preferred, optical as backup) → DAC coaxial/optical input
  2. DAC analog output (XLR preferred, RCA as backup) → amplifier
  3. CD player settings: set output to “PCM Only” or “Bitstream Passthrough” — ensure DSP processing is bypassed

Important: CD Player Must Have Digital Output

A CD player with only RCA analog outputs cannot be used as a transport. Always verify the CD player has “COAXIAL OUT” or “OPTICAL OUT” before purchasing for this purpose. Most DVD/Blu-ray players also have digital outputs and can serve as temporary transports.
