Red book CDs sound exactly the same as streamed equivalents on my system and Qobuz typically sounds better because of the higher resolution. So, it is simply a matter of equipment.
I have used iPods, iPhones, iPads, PCs, MacBooks as streamers. If you want really good sound you need to move beyond those. You need to use a dedicated streamer to get excellent streaming sound quality. The level of streamer you need depends on the level of the rest of your components. If you have a $10K system, maybe a $1.5K streamer might do it. I have a $17K CD player and a my $22K streamer sounds exactly the same with red book CDs… but is usually bested because of Qobuz’s greater resolution on many recordings. What ever your level, it depends on your equipment.
I recommend you look at Aurender streamers… I have owned Auralic as well and settled on Aurender, and own two, one for my headphone system (N100) and a W20SE for my main system.
