Good question! During development, we found that design decisions always involved making tradeoffs between size, flexibility, power, and cost. Increasing the output power increased cost, and so did keeping things compact and keeping the input voltage flexible.
For power supplies of this class (output power, number of outputs, etc.) the Hydra is actually competitively priced.
We have some exciting plans for future designs that will cost a little less, but (of course) the tradeoff is in flexibility and output power.
