Yeah, I think the 4pairs should do just fine for most use.

I was only thinking about those extreme cases with hugely reactive loads, to make it as bullet proof as possible. But for now the 4pairs looks really good and robust enough.

The limiter should prevent the abuse that goes beyond what it can really do, and since that would only be in the rarest situations, it'll work.

I ran noise sims yesterday, after taking the reading on the damping factor, and found a SNR at a little over 123db. Not too shabby is it?

The 2n3055 and its complementary MJ2955 was an "all terrain" output transistor

The most sold amplifier in the 80s, the famous NAD 3020 used the same.

I am the owner of this amplifier, I just had to change the capacitors of the power supply and it still works like the first day.
