Only to a point but not a whole lot IMHO only. You may want to read up on this site and probably the NAD site to see what some of the experts say about dynamic power instead of fixated on the often useless continous ACD power in real world applicaions. Also, be careful with the hearsay things about the 'high current' deal. HK, NAD, Denon, Yamaha, Onkyo all claim high current but it is meaningless by itself without more detailed information to support such claims and more importantly defining it first.
If you understand (NOT saying you don't) the basic electrical theories, current, voltage, power, impedance are all inter related so don't think for a moment that you can have a 200WPC into 8 ohm amp with very low distortion would not deliver the current that an expensive 50 amp would deliver and this is just an example.
