Al,
good point. I thought about it when I read the list. From my experience the majority of Arms (inside) is far away from its possibilities based on their cheap, average cable inside. For example, a cheap Rega Arm can show very good results when it will be rewired, you can simply get the most out of it with such a modification. When all is done to get the best out of any Arm, then it makes sense to go ahead (not everyone can afford everything but when you have something which can really deliver what is possible from its design, it can be absolutely fine). Various SME Arms are another example for internal wiring.
Some Arms have good wire inside (Graham for example), here it makes sense to link a top cable from its connector to the Phono input.
Or another example, when you work with Headshells, most are delivered with very cheap leads. When you replace those with top leads, silver or copper, you hear immediately the difference, for a small investment about 35-60$. The cartridge signal is so fragile, you can't improve it, but a lot can be done to degrade it.
