The diversity is not a bad thing but the problem is the actual status that the cable mount plug is not unified.

As for full-size balanced amp, there was Headroom black-head which was the only balanced amp at that time. So the two XLR plug was the de-facto standard of the balanced amp.
The black-head was compounded with two stereo amp bodies so the plug need two separated plugs. This is a historical reason so rethink of the plug termination to fit the smaller body is not a bad thing too. But anyway the cable plug should be unified or we can not share the headphones. Especially for portable amp fanatics who has many amps like me.

I hope any manufactures that now thinking to make another portable balanced amp to follow any of these existing ones.

An intermediate universal plug with RSA type male/female would be another good solution I think. Now my reference portable amp is Hifiman 801 so I still need single-ended mini plug anyway.
