This is a great time in digital to be getting into high end audio..
First an overview. A streamer and a DAC are components like a preamp and amp. They both deserve the same consideration and investment levels. A Mac book or PC is a very inferior streamer. The best services are Qobuz (1), and Tidal (2)… most the rest are notably of lessor quality. These costs around $12/ month. Qobuz gives you access to well over a half a million high resolution albums and millions of CD quality albums. You need never purchase music again.
It is best for high end equipment to have a separate streamer box and DAC. Both strongly determine the sound quality. My rule of thumb is the reseach and buy the very best you can in both categories and it is likely a well balance system will end up with the cost of each component around the same, so streamer = DAC = preamp = amp.
Streamers (take a look at the Aurrender N200… for instance is an outstanding streamer). You plop it down and it will connect directly with Qobuz and you control it through an iPad. I highly recommend Aurender. They supply outstanding low end audiophile to the very best streamer on the market. I own one at each end.
The sound quality is primarily based on your equipment more so than the specific format (resolution). Recording variability will cause more difference than will the play back resolution in general. While there are exceptions. Over the last couple years I have listened to my streamers about 2,000 hours. I will frequently be surprised how good something sounds… I will think, “now that must be a high resolution recording”. I will look and it is only a red book CD quality… but a really good recording. The opposite occurs as well. So, the important thing is to work at getting a top quality streamer and DAC. They both matter.
A high quality streamer can be connected to the internet using a wall wart wifi extender. So you run an Ethernet cable to a nearby outlet where the extender is. Some folks go through elaborate exercises to “clean up” their whole internet signal… through fancy routers, power supplies, filtering devices. It is much easier just to buy a good quality streamer. It isolates the signal and output and provides a well timed signal for your DAC to use.
