Digital phase

[Emit]

I have "inherited" 4 digital phase speakers. Qty. 2 acousta- reed bass ap5 81db ,one watt one meter (2.83volt) 60watts 13"h x 9" d x 8 1/2 w.
Qty. 2 ap2 92db, one watt one meter (2.83volt) 150watt. 42"h x 14 1/8 d x 13" w.
They originally used a avr20 harman/kardon receiver any ideas on a worthy replacements?

Replacement of what? Amp? the low efficiency of speakers doesn't tell the whole story

Sorry for lack of info. The amp is mia so I'm trying to find a good replacement for this. The speakers are known to be amazing.
