normally are counted for a 6-stage power amplifier
but the timing of the feedback requires a lower number of steps
this amplifier is a modification of M LEVINSON NO 20.5

the input is the inverting and requires a buffer

Stee, I don't know how you count, but almost all power amps have three gain stages.
The input stage, often balanced/long tail pair; the voltage amplifier often called Vas or TIS (transimpeance stage) and the output stage.
In your circuit I also see 3 stages unless you count the driver emitter folower as a stage, but normally we only count gain stages.
BTW the 'run time' of the feedback signal through the stages is irrelevant. People often confuse it with phase shift.
