Did you notice....

I have the Naim Uniti Atom streaming from Apple Music and on what’s in my iPad. Driving a Benchmark AHB2 or an Anthem MCA 225 GEN 2 or a Carver Black Magic 20 alternately. Great.

Guy must have a crappy streamer!    He already said he has a cheap CD player?   What’s he comparing it to ?

In some cases people have their systems tuned to deal with all the issues associated with analog so when pure clean accurate digital comes into the picture it is a problem that requires more changes.

In other cases the reverse is true.

In others, nothing is really all that good so there is no source for reference

Still yet in others the stars are aligned and everything sounds similarly excellent. But this usually happens by design, not by chance.

Just do it well no matter what and it will all work out.  Otherwise probably not. 

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 read responses to the question.  What is "Outperform" is What? I hear advantages in both depending on the music and age of CD. Type of mixing and EQ. With streaming you might find the same song mixed. EQ better than what the CD had. Strictly RedBook? I have never heard one so have no idea.
