in this case the more the better?

Higher is easier on the amp (less distortion since its drawing less power) but quieter (again because of less power).

That guy is clearly an idiot though.
maxpancho:
well, and again, what's better to have in this case? 30 or 60 ohm phones?
soap:
Depends. At the same sensitivity rating the 60 ohm ones will be quieter, but will they be too quiet?
But 60 ohm phones can be louder than 30 ohm phones if they are more sensitive. Saratoga will have to answer that (how many dB is the change from 30 to 60?)

Better how? The question doesn't even make sense.
If you're not interested in understanding what impedance means, maybe you should just not worry about it . . .

In general twice the resistance means half the power, but since you're also changing the amount of material in the headphones, the sensitivity changes too, so it could shift either way. In general though, very high impedance headphones tend to be quieter. The trend isn't so clear in the middle (they make incredibly loud 32 ohm IEMs for instance).
