Qobuz is the best sounding service and has over 500,000 high resolution albums.
Streaming has a very low network demand. My system works without hitch when my iPad will not refresh a page. I operate my two systems with dedicated streamers using a wall wart wifi extender… so the dedicated streamers do not need internal wifi. I know of many +$150K systems working this way.
Streamers are critical components, just like preamp, amp, TT, or DAC. Streamers can provide better sound quality than a CD (those high res albums), or at least as good as CD when the same red book format is streamed. I had 2,000 CDs…. I gave them away.
‘I have been streaming and used everything from iPods, PC, MAC, iPads and dedicated streamers. In general, a dedicated streamer will be vastly better than other option. You can see my current systems under my UserID.
If you choose wisely you get what you pay for. I have owned dedicated streamers from $3K, $5K, $10K and $22K. In each case the sound quality tracked with the cost. While I owned a Aurlic Aries G2, the remainder have been Aurender. Aurender only makes streamers. Their flagship is the most used in audio shows because of its sound quality. I highly recommend Aurender. It does not support Roon. I have used a number of PC and Mac based control software. I am very happy to leave that connection in the past.
I prefer to have a box… like every other audio component. Slap it down and start playing. They have a software app (Conductor) to access streaming, any stored files, connect to your NAS and thousands of internet stations. It is highly regarded, however is not a Roon. I like to listen to music, and with the streaming output on my system equaling the sound quality of my vinyl rig, I find Conductor very good for finding, and consolidating my library… of files and streaming albums/songs.
There are a contingent of folks that have implemented elaborate high end audio network routers and auxiliary boxes and cables and believe they are getting outstanding sound. My feeling is you can do all sorts of contortions or get a high quality streamer. I was in IT for well over thirty years. I got the fiddling out of my system. I want to sit down and hear reliable audiophile level sound quality and not fiddle. A high quality streamer gives you this.
