In general:Class A:
- Heavy due to robust power supply required for continuous high power draw.
- Case or heatsinks very warm to hot just sitting idle after an hour.
- If you measure it's power consumption at the AC outlet a Class A amp will be drawing a significant amount of power (Watts) even if it's just sitting there idle not playing music. Could be as high as 100 Watts or upwards of several hundred Watts at the AC outlet depending on the power output rating of the amp.Class D:
- Most Class D amps are relatively lightweight with the exception of those that use a linear power supply and/or unnecessarily massive casework. Most Class D amps use switching power supplies.
- Case should be cool to barely warm to the touch whether sitting idle or playing music for an hour.
- If you measure it's power consumption at the AC outlet a Class D amp will be drawing a very small amount of power (Watts) sitting idle and not playing music, probably under 10 - 20 WattsOne easy way to tell is to use a AC Watt meter:
