Streamer recommendations for dummies.


I’m new at this.
I need an e-net streaming device for AirPlay that can be set to a specific gain to prevent iTunes users from overwhelming my amp with the preset volume on their device. Anything above 60% is too much.
It would be nice to be able to EQ at the streamer as well, but the big problem is volume; when an iOS or OSX device sends a song to my amp at high volume (ear bud volume) it basically blows my bookshelf speakers off the stand.
Equipment:
amp: Hegel H160 -150 W RMS X2,   32-bit AKM DAC @ 24/192 except USB at 24/96 on 1 GB e-net.
speakers: SF Concerto on stands.Ben

The Node2i has four gain levels, disabled, track, album and smart, treble and bass tone controls and volume limits. It is also Airplay 2  though I have never used it.
Thanks, I was looking at Node2i, very nice... so I guess the volume limit control would allow me to set a max gain into the Hegel?
Wonder how much better it would sound over the built in DAC...
