Tvad,
That's a good question, and one we discussed internally at length after it became clear that there was a recurring problem when including an inexpensive PC with a Hydra 8. We initially included the Diamondback standard with Hydra 8's in '03, though it was a real stretch for us at the H8's retail price.
The problem was that many who bought the H8 had high current amps, multiple components, and were using heavy gauge AC cords to components. Some customers were buying a high-current capable power distribution package that included a smallish 12 gauge AC cord (DiamondBack) to the wall--often with 10 or heavier gauge AC cords to components.
Initially, the Hydras failed in some applications only because the cord to the wall from the H8 was the smallest gauge cord in the system, yet was responsible for 5-6-7-8 components worth of current.
We made the decision in late '03, when we started to introduce the less expensive models, to have the dealer offer stock, but encourage system matching based on the electronics, existing power cords and system make up.
In our opinion, putting stock PC's with the Hydra gives a Halcro/PASS/ Bryston/Classe'/Atmasphere/Lamm(example) owner the idea that a simple stock PC is adequate to drive a Hydra that powres an entire system, when in our opinion, it's not. A 12 gauge cord (20A) is technically capable, but not in terms of performance. Especially if there are heavier gauge, specialty cords going to components.
Bottom line? The PC that is chosen for a Hydra, or most any other power distributor (in our opinion) should be _AT LEAST_ the equal of the highest performing PC powering a component/s.
In some cases, a dealer that knows someone is using high-quality PC's to electronics may encourage a high-quality PC for the Hydra, whether ours or another. They should however, always make it understood that a 12 gauge Belden type cord is an option.
