Quad - $640 = Temporary pricing.  Ends May.
Double - $480 = Standard price
Single - $400 = Standard price

You sure about that?

From OP
Dual version US $640 (discounted  US $480)
Single version US $480 (discounted US $400)

I look the discounted to be pre-order special pricing so $640, $480, $400 is apples to apples right?

Based on their quad thread.

At 640 USD through end of June (not May).  Price to go up 50%.  Some confusion on this thread.  Not sure what's up.

I don't think there is any confusion.

There is pre-order price:
Quad - $640
Double - $480 (50% higher per MH/s)
Single - $400 (150% higher per MH/s)

There is also the post June price
Quad - $960
Double - $640 (33% higher per MH/s)
Single - $480 (100% higher per MH/s)

Either way the question stands who would buy a Double (or even worse a Single)?

When MH/$ determines payback period having 33% to 150% longer repayment kinda makes those products nonviable.
If hypothetically you could break even on a Quad in 12 months it would take 30 months with a Single.  Is there really a market for that?

We don't expect the market for the singles and duals to be anywhere as big as the quads. There are a lot of static costs in building these boards which don't change between the 3 versions and the quad is always going to look better and yes we are going to look at something bigger and more on that later. You will just have to wait in anticipation before we show where we are going.

We have done the singles and duals more as a technology tester for people that are in say the GPU world and don't want to spend a huge amount of money trying out something rather than them being the ultimate solution.

As to shaving voltages we are already testing something along those lines on a different product that uses the same regulator circuit as Cairnsmore1 and it might make it to Issue 1.2. More mundanely we are going to do some performance testing against voltage settings and then set the regulators at where we think is maybe the best point in production. Whilst there is something to gained out of this there are places where we think that much more can be achieved and more on that will come in the coming months.
