Supratek Cortese vs. CAT / Nagra PL-P

Has anyone got experience with the above mentionned equippment ? My current fave is the Nagra PL-P but I´ve no chance to compare it to a Supratek Cortese or a CAT SL-1 Ultimate MK II. Any comments on this ?
can´t comment on the Supratek (its not common in Germany) but I preferred the Nagra in every way. But: Nagra is much more sensitive regarding cables and source components.
I fell in love with the Cortese. So much so that I have purchased a Grange. My Cortese (only 6 monthe old) will be up for sale. Fantastic piece of equipment. I have no experience with the others.
