Streamer recommendations for dummies.

But you can't EQ with the ARIS mini - "The ARIES MINI, as we have advertised at the product launch, will not support EQ and placement compensation" For the additional money it would be nice to have EQ capability.

My bad. I missed ( brain fart) your desire for eq tweaking capability.

No, all the options are valuable to be reviewed.
The H160 does have direct streaming, like we said though, Hegel  bound the iTunes airplay volume to the amp volume and that turned out to be a really bad idea in practice.Also it's Airplay connection can disappear on some devices, no more software updates available for it, etc.Just needs a good front-end streamer that the vendor will be maintaining with current software updates as Apple will do everything it can to make it's stuff propitiatory. I'd like the the system to still work after the next iOS OSX update ....

I guess my h160 did have the streaming, I just never could get it to work correctly, maybe the h190 is better.
Oh and do not start with Apple and iOS!
With one fell swoop earlier this year they made the vast majority of older Apple devices obsolete with the iOS11 update which the vast majority of older devices CANNOT be updated to!
Say what Apple! Thanks a bunch !
So I had to buy a newer iPad just to update the Lightning DS app for Auralic which now needed iOS11!
GRRRRRRR!!!!!!!

Why would this gentleman need a Dac based streamer sucn a Node when the Hegel has a good dac built in?

The digital volume control applies to the digital outputs of the LUMIN products, and the LUMIN U1 and U1 Mini do not have analog outputs. What I confirmed last night was a LUMIN feeding S/PDIF out to an external DAC, with the digital volume control engaged.

In other words, if OP's guests AirPlay to a LUMIN, it will volume limit playback via digital out to any DAC (i.e. the Hegel H160).

For EQ, the new miniDSP SHD devices also accept AirPlay and have built-in DSP options. I don't recall if there is a preset volume setting you can control though, for when AirPlay would kick in. However the UX is less polished than some other devices which might create some annoyances for you in exchange.

Unfortunately I can't think of any other AirPlay-compatible devices at the moment that will override the source's volume setting.
