Should I add a DAC ?

Hi,

I have a Shanling CD-S100 cdp which is exactly the same as the Music Hall 25, these are the specs:

1. HDCD decoding chip
2. Burr-Brown 1732 24-bit/96kHz DAC
3. Philips CDM-12.1 transport controlled by a CD-7mkII servo
4. Thick brushed-aluminum front plate and solid chassis
5. Two digital outputs; 1 x coaxial and 1 x optical
6. Standard analog output
7. The OPA 2134 op amps are used for the output stage and low pass filtering
8. Full remote-control operation
9. High quality remote control
10. Easily readable and dimmable florescent display
11. Detachable power cord

Would adding a cheap DAC like the Channel Island Audio VDA-1 24/96 make an improvement ?

Thks,
