I use Ortofon Cart's, I have friends who also use Ortofon Cart's and between us, there is also use SUT's, Head Amp's, as well as the option to use a MC stage biult into a Phon'.
I and others I spend time with do not set limits on how a Signal from a Cart's is being transferred.
I don't focus too much on the Math, I don't get too much stimulus from number crunching. It is the Sound that is being presented and the variants of the sound (different flavours) that can be created that are maintaining an attraction that I find the most stimulating.
On this forum, I believe I once referred to a experience I had, where a demo was taking place with a Ortofon Cart' that was attached to a SME 3009. This set up was was met with posts where the description of the set up was not too well received and it was challenged as a concept.
'Nobody Died', "Get Over It". If a individual likes the idea of experiencing a SUT with a particular Model of Phonostage, then let that itch be scratched.
