You could hook a Klipsch Gate ($79 on Amazon) to your existing receiver or use a Klipsch PowerGate ($149 on Amazon) in place of your receiver. With the DTS PlayFi app on your phone, you can stream any service you like. If you want really good sound, you'll want to subscribe to the higher resolution tier of whatever streaming service you prefer.

I’m like the Arcam Link too. I’m currently using an older Apple TV Generation 3. These were discontinued for the 4’s but I like the 3 better because the back has an optical out, which I plug an optical directly into the back of my receiver and plug the HDMI into my tv. It’s very clear, not lossless. You can use either to stream music from your phone or laptop as long as there is wi-if/Bluetooth available.

...before any recommendations can be made.

What's your budget?

What are your use cases?

What's the make and model of the receiver you currently have?

Are you planning on an upgrade?
