I was in a rather unique position to evaluate them some years ago when I bought a newly repadded 10M. The resonators were basically enlarged rivets, sort of similar to the old reso pads. I had them swapped out with Noyeks within a month or two of getting the horn, and yes, the horn seemed more vibrant in my hands. The alleged science behind Noyeks has to do with the increased surface area due to the crinkles. I also had a Zephyr alto which got them with an overhaul, but it was unplayable beforehand for an accurate comparison. It remains a very lively horn.
