Spondoolies wasn't competative with Bitmain because they build their miners to be configurable, NOT because their chips were too expensive or not comparable.
If they had been SMART, they would have settled for fewer sales and NOT tried to compete on price - the same route Caanan is taking with the Avalon - except that the SP20 when set for the same hashrate as the S5 was almost identical efficiency level and ran a hair cooler.
The SP20 compared to the S5 was a night and day difference in many respects - the SP20 could get down semi-close to the high end of S7 efficiency range (at a cost in hashrate), or it could be tuned to do 50% or so more hashrate than the S5 (at a cost in efficiency), and that tuning also allowed it to handle high temps a LOT better than the S5 could.
You could also STACK SP20s, they were a lot more compact design in actual usage (longer, but lower in height and no cables/lack of a top made the EFFECTIVE height quite a bit lower, and almost identical width).
The SP20 was also overall a much more PROFESSIONAL design - it's STILL a more professional design than the S7 or S9 or even the Avalon 741.
Configurability and professional design came at a cost though.

RIP Spondoolies... I loved them! Great support and product too.
