Your dealer is terribly mistaken. PCs are terrible streamers.
I have for over fifteen years tried all forms of streamers… PCs (with all sorts of modifications), MacBooks, iPads, inexpensive combined units. Finally dedicated streamers from $3K to $22K. Dedicated streamers are the only way to get great sound.which, dependson the rest of your system. If your average component is $200 then a MacBook is fine. But if you have more than midfi components and an interest in good sound quality you want a dedicated streamer. If you have a very modest system a blue sound streamer will do. If you have a better system the carefully choosing a streamer at the same investment level as your DAC, preamp, and amp is appropriate. My streamer and amp are the most expensive components in my system (see my user ID for my virtual systems).
Get a dedicated streamer. It will have access directly to Qobuz. So you just use your iPad to access the streamer… log on to your Qobux once the first time and you navigate with your iPad from then on. I recommend Aurender streamers. They make some of the best… their flagship is typically used in most demos at shows. Mine sounds the same as my really good analog system.
