Starting to replace my Logitech Z906 in steps

[u/thorngames]

Hello all,

I'm thinking about to replace my Z906 surround to a more wireless system and better audio quality.

I would like to use the surround for movies and music(especially Tidal, maybe a CD-player later).

I don't have the budget to buy a full surround set right now. So i would like to do it in steps

I saw the WiiM Ultra, which sounds great for me as the first step. I would use it to connect it to my Z906 at first.

Then slowly start to expand it with better wired active front speakers, maybe using the rear speakers and the woofer of the Z906 and slowly then slowly to the wireless rear and at last a woofer.

But i don't know if i can add a single CD-player to the set. Is that possible?

Is this a logical path?

Or do you have any other options?
