Question about Denon Heos 7 Hs2

One Heos 7 is definitely enough. The advantage of having two Heos 5 is that you can take one speaker to another room. But in terms of sound, the Heos 7 is superior to the Heos 5 thanks to the built-in subwoofer, and for small to very large rooms, the speaker is simply enormous. And you only need to pay for standby power once🙂

The Heos 7 sounds clearer and is suitable for any room size, I would start with one (cheaper than two 5s) and only if stereo is still needed later a second one (I think even a 5 could be paired, clarify, would then only be 200 more expensive). (I have two 5's and one 7, all without stereo, each room, there is always one:-)
