Although it's spec's may be on the low side, does one really need more for a 2 channel set-up? Even running 300+ W amps, I've never tripped my 15A dedicated breaker. I suppose some concern would be aimed at choking the headroom, but with the really low voltage at the outlets here lately, it's got me wondering. Compared to most units at 3-5 times it's price, it may be worth a try. I guess I'll have to check out the return policy.
