Vintage Cable from ISODA Electric e. g. HA-20, HY-2036A, HZ-20-D and HB-55 (all Single Wire) - best Way to Connect ?

[tiefbassuebertr]

I have heard from most sellers at those days, that solder connection wasn't a good idea due additional wires consisting of aluminum.

Therefore the question: what is the best way to connect this cable to a plug or terminal ?

Concerning the HA-20 are to read the same question, but without helpful replies:

here a solder connection was created with a 4mm plug

Additional I want to know, what has been tried to achieve with the internal structure of the cable (go to attached images) ?
If I see this correctly, one strand is a relatively thick copper cable, which is wrapped with another cable, which in turn has the same basic structure (i.e. also a copper cable, but a thinner one, which is also wrapped with a very thin wire)

Maybe there are descriptions and datasheet published (maybe also a patent).
Thank you very much for upload such papers and an advice for a solution for connect terminals.

P.S.: Images of HB-55:

Unfortunately not. Send Mr. JCarr a PM with the both links from #2 - go to

Maybe he can find a current phone number of ISODA and call there.

Okay. Thanks for your reply. What caought my interest was the info about a new cable in preparation. My story short. In the fays were Jean Hiraga publiced info about the Isoda brothers and there cables I worked for a company CBC Audio / Denmark. This company started to import the product line and it was used (among other brands) as a reference in the show room but also while developing the first Primare System amps. The speaker cable really stood out and made a positive difference. But the sales was not as expected. Later on I left the company. Isoda followed me. I moved some years later into the recording industry and lost the contact with Y. Isoda. Later on, 2014 I returned to the hifi trade and I was looking for a cable brand. While habing researched the options and comcluded that nothing musg has happend I started to look up Isoda. First thing was to source some second hand cables and here I concluded that with the gear I like the cables was superior. Later I found the website but as you I got no reply. So I took the chance and wrote to Mr. Jean Hiraga and also the late Mr. Tim De Paravichini who was a close friend to Isoda. This resulted in more info and a note that they will try to connect me with Isoda. They successed and Isoda wrote back to me. I was lucky to get some samples send and also a custom build set to install in my prototype speaker. Suddently one day and after many nice mails Isoda disappeared. Before that he told me that the cables I received was his “The last swan song”. Again a bit later I was told by friends in my japanese network that Mr. Isoda has withdrawn from the trade and will as before only make small batches for the local market and sold via his network only. While knowing that he stated that the 2036 among others is the last cable from his hand then I was surprised to read that there is new in the making…………I don’t know if you know the story behind Isoda and his late brother?
