Stuart:
Here’s a pick from A-Mart of custom SA stands with your speakers (if you still have the 17.5’s).
Interesting Library Lion/Dog look to the combo (wide leg stance and a huge top plate).
This said I’ve used HR’s (still have them in storage) and they are good stands.
From one well aged back to another if I were to ever purchase new stands the spikes would have to be adjustable from the top of the bottom plate (not the bottom).
