What you describe is likely an accurate depiction of your experience in your system. 

An average cd player likely outperforms a sub-optimally implemented streaming setup. The cd player is plug and play and the designer made his or her decisions and then sealed the box. You made the technical and qualitative decisions in your streaming system: software, cables, power, ethernet delivery, file/source selection etc, etc.

No offense intended but if your Carver cd player is outperforming your streaming setup, even a modest streaming setup, then you might consider revisiting your decisions on the streaming side of the equation. Many here have enough experience streaming that your original premise is fatally flawed.

CD is better.  My kit: Aurender to MSB DAC.  MSB TRANSPORT to MSB DAC. STREAMING OPTIMIZED WITH UPTONE ETHERREGEN SWITCH , AUDIOQUEST Diamond USB , AUDIOQUEST Jitterbug .  Power cables all exactly the same ;Transparent Audio Reference.  Cd is easier on the brain and holographic. 

I’m curious why would you have an Audioquest jitterbug and an Audioquest diamond usb cable in the chain between your Aurender and your MSB dac? Do you have the pro usb msb interface? Unless you have an Aurender that only outputs USB then why wouldnt you compare a burned music file from the aurender fed through AES/EBU to your MSB dac? The reason I ask is I have done the same experiment and there is little discernable difference between the sound quality with the Aurender sounding slightly better, which I assumed was its caching advantage over a transport only. The usb output of even the most basic Aurender when fed into even the base usb input of a MSB discrete dac would not be positively influenced by the Audioquest Jitterbug.
