Headphone Distribution Systems - Aviom, Elite Core, others?

I don't have any experience with any of these. I looked into them a while back but decided on something completely different. I bought a used Behringer ADA8000 and a handful of used behringer 8 channel mixers, which I mounted to cheap mic stands. I used the ADAT-to-Analog conversion in the ADA8000 to interface from my DAW and A/D to a snake with 8 channels (4 stereo pairs). This way, I create stems from the drums, vocals, guitars, and bass and can route this out to the mixer "pods"

Now the artist can not only set levels, but can essentially "mix" their own headphone mix to their liking. It's a lot more DIY than you might want, but it's a lot more flexible than just a bunch of outputs.

I've had a ton of experience with both the Hearback and the Furman both as an engineer and a player. Out of those two, I would recommend the Hearback system all day. It depends on what kind of band you're tracking, but there have been very few times where I've not been able to make the 8 channels work. The Elite Core stuff looks awesome, but for double the price not sure if it'd be that much better.

I was wondering if that Behringer system was any good. I think I only have one piece of Behringer gear, a Powerplay HA4700 headphone amp. I've had that thing for probably 8 years and it's still going strong. I think it's been dropped accidentally at least half a dozen times too. :-)

I never really used the Aux feed. My layout would usually look something like this:

Drums - Stereo 1-2
Bass - 3
GTR - 4
Keys - 5
Vocal - 6
Click - 7
TB - 8
