One cannot conclude that from the graph microstrip showed imo , but its never a bad idea to do a calibration check , that goes for both machines , but you need a GOOD tech
The studer has the expensive tubed out put stage , Ballfinger had to built a whole tapemachine within a certain price perspective, a ss outputstage gives a less warmer sound in general and different bass ( I m certainly not saying less or worse depends on the design )
It would be the best to get a ballfinger with a direct heads heads out included for comparisons .
What i would state is that the turntable sounds very ¨ sparkling .¨ compared to the tape
But this is of you tube off course so its not the whole picture
