Hi Audphile1,
Your experience mirrors mine.
For my ears, I can always hear better sound, because it is less forced even at higher volumes, more engaging - i can listen for long periods without fatigue - and the sound is just, well, more beautiful to listen too. When streaming is bad, my music-lover brain switches off to the music. I listen for perhaps 15 minutes then switch the amp off. Unfortunately, its been my experience of streaming from cloud services such as Tidal Qobuz or Apple, that as of late, the sound is too often unsatisfactory for longer listening.
I believe the reason Tidal sounds sometimes acceptable and sometimes better as a high-quality source than Qobuz is their space algorithms. Apple has implemented this ‘space’ algorithm in their streaming service too.
I am of the opinion that streaming a digital file, unadulterated, over today’s networks that are capable of high bandwidth, can yield results on par, or perhaps even better than CD. However, the problem is the file is not sent and received in ‘native’ pristine fashion. It is compressed then de-compressed - what have you - and the result to my ears is smearing, vague sound that is most obviously compromised in terms of imaging, with homogenization and distortion.
In contrast, I pop in a CD and more often than not the sound is clearly better, more resolved, and precise than the streamed version of that music (George;s point is well taken here). Notably the sound is less smeared with better imaging, more tone color and better texture. The sound presentation is more resolute, more defined and more present.
This isn’t always to be the case. Sometimes it seems to me a switch is flipped and the the cloud stream sound is so much improved. I just wish it was more consistent. For now, I am considering giving up on streaming, as this is frustrating.
