Title.
Some amplifiers are marketed with “Current of XX Ampere in each channel”. I googled it and the only thing I managed to find was some forum expert saying “Current is more important than wattage rating”. But I still don’t understand why. Ohms law is still ohms law. Doesn’t matter if you advertise one or two of the factoring numbers from the equation.
Parasound advertise their amplifiers with current rating. Does is matter and why don’t other brands do it as well?
As many note, when the speaker impedance is low, more current is needed to maintain the same power (watts) level. Generally, the lowest impedance is in the bass range, where you want to have maximum power available.
I notice that when I use a high current capable amp, such as a NAD or my Adcom, the bass sounds deeper and more full on my 4 ohm speakers than when I am using a receiver that does not have the same current capacity. For Class AB amps, weight is a good indicator of current capacity (heavy transformer).
