Very interesting to see a CD player using the TDA1543. As the partnering 7W integrated amp has a 'current mode' input, what's its current sensitivity (or transresistance if you prefer)?

model S502i ― for current-mode signaling
Input: RCA jack (unbalanced), current-mode (0Ω) ×2, voltage-mode (680Ω) ×1

Thanks for that - do I take it that 'zero ohms' means the input's the -ve input pin on an I/V opamp?

Incidentally 'voltage mode' looks a lot too low impedance at 680ohm.

No indication then how much current input is needed to drive the amp to full power?
