I did name the PrimaLuna amplifier in the review text and even provided
a footnote to the original review by Robert Deutsch.

If you read my review more carefully, you will note that the basic
character of the YG loudspeaker remained constant throughout all the
amplifier changes. Each amplifier brought about a slightly different
emphasis in one or more aspects of that character, with the PrimaLuna
giving the best balance of those aspects.

The item that caught my eye in your review was the identification of a large series capacitor in the network. That's very rarely seen in speaker systems and one wonders why since this is a sealed-box system. I see no good reason for it.

It's not often done because big capacitors with tight tolerances are hard to come by and expensive, and it also messes with group delay of the response.

Yes, good point. I've seen that usage on the occasional speaker.
In this case however, the nearfield response measured by JA doesn't exhibit any boost in low end. The flat response corners at 50Hz and heads immediately south from there. It seems to increase the normal roll-off rate from 2nd-order to 3rd-order for no good reason.
Oh well.
Cheers,
Dave.
