To add to that, "high quality" electrical componants come with 2 main benefits. Better tolerances for values like capacitance for capacitors, resistance for resistors, etc, and in the case of mosfet and semiconductors lower internal resistance /lower switching times.
Higher efficiency amps literally gain their efficiency by using parts with closely matched values and lower resistance. The smaller tolerances reduce signal losses, tighten up voltage differences, and more evenly match evenly component in the chain so that no one part is being worked too close to its limit, and the lower resistance of the mosfet gate while open decreases energy lost as heat, or reduces idle current draw while closed.
Heat, resistance, and current draw are the main values that determine almost any electrical circuit. And all three of those are linked in one way or another. Less heat = better efficiency, end of story.
