I'm not sure it matters to most of us ... I'm a fan of Clear Audio. I don't own their stuff due to price point and lack of availability in the used market here. But, that does not mean I don't appreciate what they do.
Sourcing parts from one, or more, companies is good business. It leverages economies of scale and reduces tooling costs. AT has patented technologies and they are making a return on that R&D. Who's getting hurt here? No one as far as I can see.
Just like Dr Benz when he left Empire. He had to source his stuff somewhere.
There are more than three bulk cartridge makers in Japan. Nagaoka, AT, and another I can't put my finger on. There are also three of four stylus houses. Most will sell you a stylus to fit your AT (or whatever). Do you think they only remarket?
I suspect they all collaborate and mount individual components like their own diamond design, or cut in parts from the other guys - at least some parts. Who'd want to tool up to set dual V magnets when AT will sell you a stub with the magnets set. You could then insert you own bonded tube extension and diamond, or have one of the other houses do it for you. Contract work. Done all the time, all over the world.
It's the sum of the parts and the design tuning that gets the final result.
And I'd take the speaker challenge. Say an MCS vs a Sony. That would be about as far apart as you could get in my modest SS collection. Warm and tuby, vs flat and analytic. If they all have to be current production gear, yeah sure they might all sound similar (integrated transistor packs and all that). But, if they allowed classic gear, I'm sure most of us could rise to that challenge. But who is going to pay to get both pieces benched and in perfect spec so that there is no weasel room on the outcome? That's about $500 where I come from. Then shipping and air fare, meals, lodging?
I'm guessing Harbeth won't cover the cost? So how's this supposed to work? Same for AT vs Clear Audio - who's going to pay for the costs of the tests under lab conditions? Me, I don't think so - I already know the answer. In my house with my speakers and my LPs, things are different - amp or cartridge or whatever. Jeez, I swapped enough gear in the last 5 years to know that easily. It's why I have a cartridge library. And one day I'll add a CA to the list (I already have enough AT's, thank you)
