Requesting recommendations for simple and easy to use music streaming devices

An unusual question please:

I’m setting up my first and probably last audio system. I’ve used headphones before, but never speakers. I bought the Graham LS 6 speakers which I bought for their rich mid range. I was thinking of purchasing a streaming integrated amplifier because I thought an all in one would be simplest to use, and I was considering an Arcam SA 30 as it has both enough power and I’m told it would nicely preserve the rich mid range of the speakers. However, as I started to read about it I got scared off because as a senior I am, sorry to say, completely helpless when it comes to technology and the SA 30 has so many features there’s no way I could really use it. I would very much appreciate any recommendations for a streaming set-up, all in one or separates (integrated  amplifier plus streamer?), that would be easy enough to use. I don’t need a lot of features because I will only be using it to stream directly from streaming services (Amazon HD, TIDAL and perhaps others in the future; I will have none of my own files; no CDs; no phono). Any suggestions for a system, integrated or otherwise, that would be able to properly drive the LS6 speakers (8 ohms; 87 dB’s; recommended amplifier power 50–150 watts) and preserve their rich midrange, but also as simple and easy to use as possible? Budget could be $2000-$3000, but, again, simplicity is critical. I know it’s a difficult question because I am asking for two probably inconsistent goals: good sound and simple to use. Thanks very much.
