Complicated subject which should include inductance. Any coil of wire is also an inductor, like a speaker coil. Having inductance as an electrical property of the cart output (HO) has the affect of lowering the high frequency resonance of the cart. In this case it's the shunt capacitance of the cables and phono stage that comes into play because it's the combination of capacitance and that inductance that causes that HF lowering. Sometimes this is used to "tune" the output by augmenting the treble, hence capacitance recommendations by a manufacturer. Cable resistance doesn't really come into play. I have seen low inductance cables made for LOMCs.
In general it seems that HO carts with < around 500mH inductance and < around 1200ohms, perform best. This would be impedance, not DC resistance. It is possible to have a nice sounding HO cart that is outside these parameters, but chances are it's not "state of the art". High inductance/impedance carts like the Shure M97 or Stanton 681 tend to be mellow and the better ones like these have their appeal and compliment some systems. AT (MM) carts need very low shunt capacitance, < 200pF. That's hard to do and is much of the reason IMO for the overly bright house sound perception.
Capacitance doesn't matter much (usually) for LO carts. Self-inductance is typically in micro Henries and only comes into play when output is very low which requires alot of gain, and cart impedance is relatively high (30 - 40 ohms). This high impedance can be assiociated with high inductance and can cause ultrasonic ringing in a phono stage with extended bandwidth. If you have a cart with 33 ohms impedance and have to load it at 33 ohms to get it to sound right, chances are this is what's going on. I haven't heard this about the DL-103, just the DL-S1 and 304. Those two must have very high inductance due to nonmagnetic core coils. BTW, loading down a cart at its impedance will cut the effective output in half.
