No point in our getting into a private back and forth here, but please do not take what I wrote as a criticism or an insult. Most of all, I would not insult your cartridge collection. I hope you would admit that you are a champion of MM and MI cartridges, by and large. That leads me to think you listen to them most often, compared to time spent with LOMC cartridges, regardless of how many you may own. I was just trying to understand why you feel so categorically that DIN connectors, headshell connectors, etc, etc, do not make any difference to SQ. In my own experience, those connectors in the phono signal chain do have little effect with high output cartridges, but not so with LOMCs. So I was projecting my own experience to yours.
I do own an FR64S with B60, by the way; I don't know why connectors would make more or less difference with an FR64fx vs an FR64S, but as you say, I don't own the latter. I would also say that the match of tonearm to cartridge seems more important than the number of connections. For example, my Koetsu Urushi sounds far better in my FR64S (using an Ortofon LH9000, 18gm headshell) than it did in my Triplanar, despite the fact that the Triplanar achieves direct connection from cartridge to phono inputs. So my generalization (that physical connectors DO make a difference with LOMCs) does not hold up 100% even in my experience. That's another reason why I was wondering about your level of certainty.
