Hi Vaughan,
I would suspect that the Goldenjacks and the Rothwells (and any other similar attenuators) all differ somewhat in terms of the resistor values that the designers chose, and possibly also in their internal circuit configurations. Those differences, and how they match up with the component impedances, would likely overshadow any differences in resistor quality.
And neither manufacturer seems to have internal design details presented on their website, which makes it all hard to predict.
If the 10db attenuators seemed to have minimal sonic impact, though, and if 10db attenuation was insufficient, why not try having 10db attenuation at the preamp input and another 10db at the power amp input?
Best regards,
-- Al
