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?
NAD uses small power supplies, that is their “virtue”. Show me an amp with high dynamic range and I’ll show you an amp with an undersized power supply.
NAD Hybrid Digital amps, whether Hypex nCore, uCD, or Purifi, all use PWM power supplies that are highly efficient, unlike conventional supplies, and all their power ratings are conservative. It’s a big point for them. The era of soft clipping and +3dB headroom was the 80s, long before Class D was in vogue.
