Difference between non and factory terminated

I'll chime in here and offer that one would not hear a difference provided the terminations were the same products from the same manufacturer.

Tvad - What if the IEC connector and wall plug were of a comparable or better quality than the original, but not the the same as the original? In this case, the non-factory terminated cable couldn't be worse than the factory terminated one, could it? (barring a sloppy termination job). Would it sound different? Would it sound better?

All bets are off because there are too many options for alternative wall plugs and iec connectors to make a good judgement. Take a look at the VH Audio website to get an idea of the range of connector options.

Octuple (love the user name BTW),
I'll chime in only to agree with what Tvad had already written. And as you mentioned earlier, the hit to the resale value is of concern for those of us who like to try out different cables. If the cable is a keeper, then depreciation is irrelevant. Sorry I can't add anything further. I think the question has been fully answered.

Thanks everybody, for your input!
