Hi everyone,
please excuse my poor english, I just registered here to answer the last questions: The Bionors were real, the seller was intimidated, due to very bad experiences he made selling an EMT 927 years ago. He inherited rare audio gear from his father and asked his son to advertise the Bionors.
The Bionors are complete and original except for some bolts and nuts that are newer. They were sitting unused in a studio for the last three decades. The KL L-302 compression drivers are a very good matching pair with original diaphragms, the bass speakers are also in very good original condition, so is all the woodwork.
I own an original JBL Paragon from around 1970, JBL Everest DD-66000, JBL 4350, first series from 1973 with aquaplas coating on the bass drivers, early JBL Olympus with S7 load, Altec 604D "Super Duplex" in custom made cabinets etc. and so I can do comparisions with a certain background regarding older, respectively vintage horn speakers.
Im deeply impressed by the sound of the Bionors, they have a special quality that I didn't expect and that touches me deeply.
So don't blame the sellers, they were real and had made very bad experiences with people, mostly dealers who tried to get vintage audio gear for unfair prices. They even supported and organized the transport, I spent a day with them, impeccable and gentle people.
10 years ago I had a similiar experience, a student in Berlin offered an early EMT 927 / R80 he was given for free from an older friend and former studio employee via a german HiFi forum. People blamed him, no one took the offer for serious but the EMT was real and very affordable, so I bought him.
There are also buyers with bad and sometimes criminal intentions.
Best regards
Michael
