Hello Guido,
Is Rowald 312 class D amp?
If so that would be first true balanced class D amp on the market. THE question is why????
Having TRUE balanced inout as Spectron does means that you take both halfs of the signal from both phases and then sum them and in the process you reject some noise and hum. Its great. Today, I learned, form user "Molly" that combo REX preamp by BAT with Spectron dramatically improves quality of the sound when he used balanced output of RX, balanced interconnect and balanced inout of Spectron.
OK, after you summated your signal you process it as FM radio does - pulse width modulation and I do not see any (well almost) advantage to continue it in both phases. There is large number of potential pitfalls in such process. You can do it for marketing purposes but regarding the noise or signal you have no advantage and you can pay price (almost ceratin in group delay consistency). You never heard of balanced FM tuners, aren't you? The same reason.
On the contrary, in linear amplifiers, the balanced signal path continues to benefit sound - IF (IF!) some conditions are met and we will not go there.
Hope it helps.
Simon
