The lower the source impedance the less the non-linearities of the load modulate the source to decrease distortion. You can do better than that. At LF, tranformer distortion is purely 3rd harm and goes away if you have zero resistance in the windings. If yours aren't wound with the tresses of Swedi...

So more reliable, smaller, more accurate for the purpose, cheaper ... behave like capacitors should .... only thing missing is the "hand carved by virgins from Unobtainium" label.

I rather liked the polystyrene dielectric, while the parts weren't very compatible with modern manufacturing processes. Was your preference for NPO/COG related to size and value accuracy, or something else? JR Calrec desks were all made to order for broadcast orgs. at the time, so no flow soldering...
