First, there is a thriving DIYer population that would have/does have no problem re-wiring vintage pivoted tonearms to suit whatever is one's preference for type, quality, and length of wire. There are even a few businesses that do it for the timid.
Second, if one is purchasing a new pivoted tonearm, there are several manufacturers, including, to name only three, Reed, Triplanar, and I am fairly sure Durand, who will supply said tonearm with just about any internal wiring one's heart could desire (copper, silver, cryo, elfin, etc) and said wire can be ordered up to go all the way from the headshell to the phono stage input jacks. Both my Reed 2A and my Triplanar are thus configured, based on my philosophy that the best connector is no connector.
Actually, Herb Papier, the original designer and builder of the Triplanar, is to be credited for being a very early adaptor of the "straight shot" wiring scheme, 15-20 years ago. I grant you that all the named brands of tonearm are expensive and may be beyond the reach of many in terms of cost, but then there is in fact the DIY route or buying "second hand" on Audiogon, etc.
This is no criticism of your ET tonearm, and I think you made a good choice to avoid connectors in the signal path when possible. If I were going to a tangential tonearm, I would also strongly consider the Trans-Fi. But I don't like air pumps.
