Using a good DAC and CD transport will make a difference.
The accuracy of the data stream to the DAC is very important. The comments suggesting otherwise may not be the best advice. However, if you can not hear the difference why bother.
If you can hear the difference then spending your money wisely is a good plan. I would suggest using a belt drive CD transport is worth the money. The performance will beat the direct drive.
I am not a fan of the Chinese knockoff's.
I would also like to point out that I am the CEC distributor in the Americas. Follow the link for more information.
