VDH do have some weird ideas, that 'Second' cable has an series resistance of 36 ohms per metre, most other balanced cables are much lower, for example the Van Damme balanced I recently used has a series resistance of under 85 ohms per Kilometre.

That would have a serious frequency roll off at any sort of length, for example;

-3dB point would be 20KHz if the cable was 1.8m long.
-3dB point would be 16KHz if the cable was 2m long.
-3dB point would be 7KHz if the cable was 3m long.

The Van Damme cable would have -3dB point of 3.7MHz at 3m long to put it into perspective.

These are simplified calcs, only taking one leg into account with no load, so best case!
