Fair. The price increase on the S9 definitely impacts calculations:

S9 14000 GH/s @ 1372 Watts @ $2725 => .098 Watts/GH and $.195 price/GH
821 11000 GH/s @ 1200 Watts @ $2150 => .109 Watts/GH and $.195 price/GH

Basically, at $2150 for the Avalon 821, you're paying approx the same cost per GH, and it's only slightly less energy efficient. Anything less than that would be a win over the latest batch of S9s.

Mikez_nj, where did you find the Avalon 821 price to be $2,150? On their web page, they are only selling in bulk for 60 units, but without price disclosure.

I don't have a price. My point was that $2150 is approximately the inflection point where the value is the same as the S9 (solely based on the numbers) - so anything below that is a win over the S9.

The announcement this morning makes this much better.
