So after reading this review, i am to believe that power is generated from the Bruce Nuc. plant then sent many many km's (miles) to my house, through my electrical panal in my garage, then trough my house using 14/2 coper wire to my wall socket. And then they would have me believe a cable from my wall socket to my component is supposed to make all the difference in the world. And now, the (directional) fuse inside the unit will is supposed to make me see the new light. Ya right!!! What is the old saying "you can fool some of the people some of the time..." you know the rest. Aren't there laws against this stuff in this country?
Nothing suprises me anymore.
Buyer be aware!

Rick, some of the previous replies probably covered this, but it's more than just semantics as to what causes the increased current load on the bridged amplifier.Speaker impedance is set by its internal wiring and can't be changed by the amplifier. If in I=E/R it actually happened that R was halved, besides E being doubled, then current(I)would theoretically be increased four times and power(IxE)eight times. Despite the use of the "sees lower impedance" type of terminology(including in the Rotel reply)this isn't what's causing the increased current. The amplifier is supplying double the voltage(which the speaker can be said to "see")into obviously an unchanged speaker impedance. An article which discusses this in somewhat more detail is found in secs. 3.5-3.5.4 here .
