@soix I respect your contributions to other threads but frankly in this one you have not brought much to the table other than relying on cost and other peoples opinions to support your view. I was already aware of those items before I started the thread. You said you used an iphone and did not like it, did you try some of the things mentioned in this thread to optimize it before you wrote it off?
You are right noise is an issue but if you shut down un-needed services on the phone you are left with a capable battery powered streamer. You can't get a more quiet power supply than a battery. I'm not saying it is the ultimate streamer but I suspect it may be better than many. You made an earlier comment
the iPhone is not a great streamer — in fact it pretty much sucks IME. It’s functional but so is a Toyota Corolla — doesn’t make it a great car.
That's a pretty good analogy because I think the Corolla is a great car if you are looking for reliable, economical transportation. It does everything a Lexus does for a lot less and allows you to put your remaining money to use on something you consider more worthwhile. You do know that frequently more than half of the materials cost of a piece of hifi gear is in the case, right? For some that is worth it ,for others there are better uses of the dough.
