New DAC or Upgrade exisiting CD Player

Roxbury,
Suggest you go to www.interlog.com~cfraser/dio.htm. This is a website dedicated to information about the Art DI/O. Good luck and enjoy.

If your CEC is one of the belt drive models, keep it. I have tried a stock original MSB dac and I think that an unmodified ART DI/O which can be had for $130 plus another $25 for an upgraded power supply is much better. Let the DI/O burn in for awhile and leave the tube in it if you don't get it modified, before making any judgements.
