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

Node-2 arrived today and integrated immediately with the Hegel H160, I think the DAC sounds equal and the issue of managing volume is resolved. Thanks to all who voiced opinions, I appreciate that others with  experience are willing to share.Ben
There is however one thing I don't like with node2, streaming under Hegel H160 network interface I need about 47 on volume for max gain with my speakers (SF Concerto).
To match that volume on node2 you have to go up to about 76 on the volume. Same results under Coax, RCA and Toslink. 
Don't like having to set the Hegel at 76 volume to use the Node2.Ugh ....

That's with the node2 at max output.Apparently the gain on the Hegel network interface (AirPlay) is way higher than the other digital and analog inputs.So now I have the opposite problem, yes iTunes users will not be able to crank the volume to 100% and blow out a speaker, but if any source other  than node2i connects the volume will be set to 75% (it changes the volume on all inputs if you change any 1 input).This machine is full of surprises....I'm going to mess with it a while and see if I justify the $500...After more testing I believe the Hegel DAC is better then Node2i.

That is not a surprise as I owned both the H300 and the H160 and found the DAC to be a lot better than my Vault.

Even though the 2i versions are supposed to be better DAC than previous it would have to be a major increase to best the Hegel DAC which are actually very good for an integrated amp.
