It looks like ALO is introducing a new, very powerful amp and as with most of their stuff, it's expensive. Some will say for what you get in terms of power it's not bad but it's still A LOT (you can't spell "a lot" without ALO) of money. Also, who wants or needs an amp that can drive 4 headphones simultaneously? I only have 2 ears and I think that's pretty much the standard for us humanoids.

True. 
But, think of the headphone shops that need to connect multiple headphones at once.

Goodness that's A LOT OF MONEY! 

 
It would also be pretty helpful to compare headphones for reviews though if you can run all 4 of them at the same time and just take one off and put another on.
