@mijostyn @dover : Do you know why Jico can't use MR word? because is a Namiki trade mark.
Now, what I remeber of Jico SAS samples is tha's it quality is not really top ( that's why only 500 hours as Jico specs. ).
His site does not said everything because in the contact surface numbers by Shibata stylus Jico choosed the old Shibata one even that exist 3 Shibata dimensions and one of them is 72um surface contact.
The ruby/sapphire price is a trick because Jico knows that boron is way better but knowledge level in audiophiles looks Ruby word and its ignorance makes they think is a jewel and must be better. Jico takes advantage of our ihnorance levels.
mijos, you can try at thde end you need it. In good shape go a head.
