But does a Q of 0.707 ring less than a Q of 1 - I'd be interested in your answer on that one.
Yes. Here's a fourth order high pass at 50Hz comparison between Butterworth and Bessel, measured at 50Hz driven by a not so realistic single cycle, to show that.

Indeed, it's fine. We integrate over a certain time so it doesn't so much matter what a single frequency looks like, we respond to the overall amount to determine loudness. For humans, one cycle of bass isn't enough to properly register it.

I can use an unrealistic single cycle to show what would happen at a sharp ending of the stimulus. Even when looking at 25Hz or 100Hz, the remainder rings out at the filter frequency of 50Hz under control of the damping, and at low level all the same.

Well, if anyone was curious to have a look at the Duelund 100v capacitors, here is a post Duelund made on Facebook talking about the ones that they made for the Elsinores. It looks like they will be radial. They also look to be small enough to fit onto the PCB!

I should hopefully have mine soon. 🙂
