@arnold_h Given that you cannot distinguish performance differences between the Node and CD playback, I am curious as to what you’re using throughout your system. I see that you haven’t posted a virtual system in your profile. Could you list it out for us here?
Even if you have a semi–decent CD player, you should be able to tell the difference in fidelity between the two. if not, it is likely not prudent for you to pursue a more sophisticated streamer at this time and instead look at either how your system is configured and positioned or into the components in the system that may be causing a bottleneck in performance. Once you have that sorted, and your system is more highly resolving and distinguishable between sources, then it makes more sense to invest in a higher quality, streamer.
