Dear Thuchan: IMHO the KOndo IO makes it better trhough an active high gain phono stage, I know this cartridge that I runned with the own AN SUT and with out SUT. Obviously that this is only an additional opinion.
On the other side affirm that " a well adjusted IO in the right chain " never be reached by a MM/MI cartridge is IMHO only a misunderstood ( for say the least. ) by your part.
In the " right chain " the right MM/MI cartridge IMHO competes and in some ways surpass the IO quality performance, but remember that I'm talking of levels of Excellence: nothing less. The humble and " ridiculous " looking B&O MMC2/1 are examples of those MM/MI cartridges I was refering.
Thuchan why if you always refute " absolutes " on the IO/MM_MI subject you speak on " absolutes " terms ?.
Anyway, as I said only an additional opinion.
Regards and enjoy the music,
Raul.
