Sound is subjective to each individual's ear's abilities and each individual's 
mental state.  Testing or benchmarking is usually limited to such tasks as, 
either one can ear the sound or they cannot hear the sound.

In other words, since most everybody does drugs, CD quality sound or music 
maybe extremely adequate or any anomalies are not noticeable at all.  Those 
sober will likely or may hear a difference.  (eg. Some noises bother some 
people more than others.)

The best method I've found when comparing audio quality, is usually a utilizing 
a side-by-side comparison, using a small 1-2 second clipping and repeatedly 
replaying until your brain memorizes each audio stream's anomalies, if there 
are any anomalies at all.

Not only this, but the two streams you mentioned are using two different base 
formats, not easily replicated over and over as per the previous mentioned 
testing method as you already mentioned.
