Ed,
I also have an AudioDharma cable cooker and I have used the phono cartridge adapter. I had the same concerns as you regarding the DIN male pins being smaller in outer diameter than the inner diameter of the cartridge clips. I phoned Alan Kaftan, the manufacturer, and had a long chat with him. He said the loose fit is not a problem. The key is to use the velcro fastener to secure the DIN cable to the armwand so that it can not move. Then slip the cartridge clips over the male DIN pins. All the DIN pin needs to do is just touch the cartridge clip at one point. I know it sounds crazy, and it is not the way I would design it, however, it does work.
You could also put silver contact enhancer on the male DIN pins to get a better connection, but it really is not necessary.
Cooking the phono cables made a big difference in my system. Hope it does the same in yours.
