Ich verstehe es auch nicht, es ist nicht besser als auf Englisch.

Was genau ist deine Frage?
1. TPA3118 + SE-Input (asymm) = higher THD
2. TPA3118 + DIFF-Input (symm) = lower THD
3. TPA3118 + Diff-Input (symm) + 2xOPA AFE (Diff/SE-Input) = higher THD, but lower than 1.
4. TPA3118 + Diff-Input (symm) + 4xOPA AFE (Diff/SE-Input) = lowest THD, similar to 2. but with increased Gain due to AFE
Totally unrelated to AD/BD/1SPW Modulation.
