We can have preferences, that are beyond discussion, but we also have objective facts.
Streaming is just the way the bits are delivered to our systems - the same we have with CDs, files on hard disk drives, SDDs or memory sticks . Unfortunately due to copyright and legal issues we are not able to capture the streaming content and rip it, something that limits our personnel experimental field, something audiophiles love. But the point is that, as long as the formats are bit exact, it is a technological question to make them sound alike, not a religious matter. It can take time, but we will arrive there.
The high-end is essentially an activity that manipulates the stereo signal to deliver an enjoyable experience, sometimes in a microscopic way bellow what is typically measured. Noise coming from digital activities entering our systems can affect its performance in unexpected ways - still a lot to be learned in this subject.
However, IMHO in adequate systems, top streaming can deliver an excellent performance, at the level of top analog - surely depending on user preference, as we are always comparing apples with oranges. Remember that the best of digital is a digital recording, not an analog sourced digital recording. And unfortunately (or maybe fortunately
) for audiophiles, musical performance will always bias our comparisons and we can't travel back in time.
