It's an SRPP. This will be balanced for the one specific load impedance where the source current and the sink current are equal. Otherwise, it goes out of balance and the distortion rises (speeks are anything but a constant impedance). The stated Zo is 800R -- 1000R, and that means a pretty poor damping factor that'll compromise low end sonics. An 8uF coupling capacitor seems to be way too small.
Might be OK for a quick 'n' dirty amp (eg. output stage for a SW xcvr) but definitely not HiFi.

This circuit was specifically designed (as HIfi) for the full-range , high-inpedance speakers designed by Philips.
These speakers are still available on Fleabay

I suppose it depends on one's definition of HiFi...
