Finally found some resolution.
STAX USA never replied to several calls and emails over 3 weeks. What a fuckhead, as I had bought a SR-007 Mk2 from Yamas earlier.
ElectroMod did not reply to one email sent. A forum member here wrote to me that Mark there might be on vacation, so I continued to look elsewhere..
ECT out of Hong Kong replied and after much back and forth, Audrey there told me that they could not sell the cable separately. They are still out on the long CNY/Spring Festival holiday there, so nothing more to report.
So I contacted the Canadian STAX dealer, Plurison in Monteal. Great response and communication. After supplying them some requested info (where bought and serial number) and also supplying a video showing where the cable was shorting with a DVM, they contacted STAX in Japan, received a quote back and arranged A&M Enterprise LTD (handles all STAX export shipments to dealers) to drop ship me a replacement cable from STAX Japan.
FOB cost of the cable was JPY28700 (~$254), EMS shipping was JPY2900 (~$26).
I forgot how archaic doing business was with Japanese companies..... requiring a bank transfer. $40 added to send and another $40 to receive on their end. Argh! Luckily I did not have to FAX them the info.
As of today, A&M has received the money, will ship and forward the tracking number as soon they get the cable from the factory. So probably have the cable in hand in a week or so.
I can highly recommend Douglas Ip at Plurison. Had a first rate experience in dealing with him. Straight forward and no bullshit.
