Adding a new "room" to my multi room setup (and other suggestion)

Hi, I’m very happy with my 3 rooms system (NAD C368 in the main room, Powernode 2i and Pulse Flex in other 2 rooms). I’m using it with Roon and with BluOS.

Now I’d like to buy a couple of speakers (finally tower, the others are bookshelf) for my bedroom (the only place in my home where two floor speakers fit, and I’d like to integrate the system with a small (and not to expensive) amp and streamer.

What are the options, in order to integrate the system in my Roon/Bluesound app? A good piece of hw, for the price, could be the Wiim Amp, but it would not fit with BluOS. Would it be ok with Roon?
In this case I would be able to group NAD and Bluesound with Wiim… or am I missing something?

The other option, more expensive, could be a Powernode Edge.

While I’m here… do you have any suggestion for a new couple of speakers to pair with the Powernode 2i? Now I’m using a pair of old Klipsch RB-15, but I want to improve the sound.

Thanks.

We finally bought a NAD M10 V3 and DALI Menuet. Thanks for the support.
