I don't know about your 70% and 30% ratio. What I can tell you is that a SIT amp which is single ended and uses a single device is pretty much as good as a good tube amp. I know - I've tried a direct comparison in my system which uses a 4P1L PSE amp. We threw in a 300b amp and a conventional transformerless PP solid state amp of good quality. The best performers were the 4P1L and the SIT.
But the SIT used an electrolytic output capacitor. The designer now wants to use an output transformer. The question then becomes how low can you get the output impedance of your output stage, so the OPT only has to do the minimum of step-down. In an "ideal world" you use an OTL tube amp, but that's a kind of circlotron - not single ended, so how important is single ended operation. That's another big design choice.
There are a number of factors here. Goes way beyond capacitors.
