Defensive much? Relax!
I just pointed out that the ATN150MLX is not an ideal match to the 440 body given identical load conditions... which is a fact. If not, AT would have the same body for both and just add the extra cosmetics to justify the higher cost.
Changing the load impedance has the effect of altering the frequency response. If that isn't altering the electrical resonance with respect to the cartridge inductance, then I don't know what is!
Perhaps you would be kind enough to rectify my ignorance by providing an explanation for AT specifying different electrical characteristics for the corresponding bodies? Poor process control? Marketing? Or could it be that, given the higher mechanical resonance of the boron cantilever (which you correctly note), they need to lift the electrical resonance to achieve a maximally flat response....
Peace!

It's nonsense. The 440 has the same generator as the 155LC, 152MLP, and the 160ML, among others. 490mH, 790/3200 ohms. They came with beryllium cantilevers while the 140LC and 142LP (same motor) have aluminum.
The fact of the matter is, if you load the cart at 47K/ <200pF, response is dramatically better with the exotic cantilevered stylus. If you ever tried it you wouldn't post such statements.

Bahahahahaa!!! You're so funny!
Show me the measurements. Don't quote other people. Show us that you actually know what you're talking about!
You really are clueless!!
OK we're done here....
