Can I use 2 different streamers in different systems through Qobuz?

@kingbr yes, I was going to bring up the lack of USB on the Prisma but since you had mentioned the Cambridge I thought it might not be important to you. Definitely a deal breaker for most people. I personally haven't heard it but would assume the Eversolo is a safe bet. I was just chatting with a fellow that has also tried a good amount of budget-ish streamers and he had good things to say about the DMP-A6. He liked it so much he upgraded to the newer and costlier A8. He went to the higher unit in hopes of using its internal Dac. I think your Pontus is plenty fine for the A6. Good luck and hope to hear your impressions somewhere down the line. 

As others have said, yes you can. I've done this when trying to compare streamers side by side. I've had the MXN10..well I actually still have it but not using it currently. The software on it is very good, I used it hardwired Ethernet. It's a very convenient piece. You can save playlists or Internet radio stations to the 4 buttons up front. You can just press one of the buttons and your saved content will stream.

Unit will go into standby after 20mins of no activity which I liked... though I believe you can adjust that time. The Cambridge has a nice look and solid feel to it. Shortly after trying the MXN10 I tried a Primare Prisma. It's a couple hundred dollars more expensive but I found a used one cheaper. For me it had better sound quality over the Node & Cambridge plus you can upgrade the power supply for more improvements. Extra expense though, plus it doesn't have all the bells and whistles of the MXN10. All in all the Cambridge is a good budget piece.
