Raul, on paper your argument makes perfect sense. But in practice things might work out differently. In my system I have the possibility to choose between various SUT’s, voltage gain and current gain devices and some cartridges have a clear preference for the use of an SUT in the signal path. Others definitely do not, it all depends.
I realise this is pretty much a useless answer to the OP, were it not for the fact that in my experience Ortofon MC’s tend to have a liking for SUT’s. My SPU’s, A95, Anna and even the old MC7500 all sound at their best with a good SUT. So I wouldn’t be at all surprised if this also goes for the Cadenza Black, which shares many of the basics with these other models. Just give it a try......
