Any cable with a 6.3mm or 3.5mm TRS plug going to banana plugs will only work with common ground amps. The Emotiva has common ground, but some amps don't, such as balanced amps or the cheap Topping T-amps. What this means is that the R- and L- terminals on the back of the amp are connected inside the amp. They are both the same ground, and they are joined again inside the TRS jack -- both connect to the sleeve of the jack. So the BTG audio adapter will work with the Emotiva, but not every amp.
A balanced (i.e. 4 pin XLR to banana plugs) adapter cable will work with any amp, because R- and L- are kept separate. TRS on the hand only has 3 pins. I built my own adapter for the Emotiva, and I only have 3 wires. My ground wire is just connected to L-, not R- at all. The HE-500 has 2 pins on each side of the headphone, so you could buy a balanced cable and a balanced adapter, then it works with any amp.
EDIT: You could also get a Hifiman to banana plugs cable without any adapter. This would be balanced and work with anything. I was interested in this as well, and asked Brian at BTG about it. He said this is the cheapest option: http://btg-audio.com/webstore.htm#!/~/product/category=2706350&id=17894638
Of course, there are other companies that can do such a cable, but it has to be custom AFAIK.
