The A50s is an older model than the L50. I think i'm correct in saying that the A50s was the first device with Topping's NFCA amplifier design.
Mmm that would be the L30, A90. Afterwards the A50 got refreshed in A50s.

since a50s only have unbalanced inputs, how can it have a real balanced output? I'm just very confused about this

The meaning of 'Balanced' applied differently between headphones and amplifiers/source io. This is a good explanation:

It gives a voltage doubled "real" balanced output but it is impedance balanced not dual mono. Some people would call it "fake" balanced but the end result is the same.
