Point of higher priced streamer?

No. It’s not confirmation bias.

Not everything matters unless there are reasons.

Most of them matters - basically subjectively.

I get it. But some facts should not matter.

Dac matters, but remote control for that DAC should not matter

as long as remote control works properly.

Have you heard about audiophile grade router?

I do not find a reason for streamer yet.

Then don't buy a "higher priced streamer". Simple. What are you trying to accomplish here? To me, it is more than clear that you have made up your mind on this already.

My point is if there is any technological aspect that I’m not aware of. It’s not just about pricing. I’m very open minded. 

If someone can tell me the technical reason, I’m more than glad to listen and learn.
Again, I totally understand spending more money for brand name and pure aesthetic. I do that too.

But when one claims there is “technically better something”, I want to know technical reasons.

If you're serious and open minded, why not visit a dealer and listen for yourself?

Why do you think I’ve not tried that?

I compare some but don’t hear the noticeable difference.
Still there is more price gap than I can understand.
I thought that I’m the one who doesn’t hear the difference or there might be more things to consider than I know.

As I explain above, in case of DAC, manufacturers are clearly aware of neutrality. They even states something like for instance, their filter 1 provides most neutral signal, but filter 2 gets the highest point from subjective tests so they recommend filter 2. - when something is out of neutrality it’s becoming custom subjective matter, and pricing is really up to consumer’s level of desire to pay.

But in case of streaming, there is no coloring (custom) factor, as far as I understand. Thus, there is no difference in sound unless some other factors kick in. I want to know this possible other factors.

I repeat that if one simply claims that streaming has different sound, it’s same as saying different router can make different sound.

Do you hear the difference? If so what would be the possible factor?
It sounds like you hear the difference, then could you explain?
