Question on if my amp is driving my AKG K340 400 Ohm headphones well.....

I think my AKG K340 headphones sound great with my circa 1984 yamaha A-1000 Integrated Amp.....(This is the old A-1000 Yamaha amp, not the newer model 1000 DSP yamaha amp...) When using the K340s with the amp, the volume knob on the amp is very sensitive, i only have to move the volume knob a small fraction of an inch to kick up the headphone volume lots....My question is, is this a good indication, the sensitive volume knob, that my amp is driving my K340s well? I know i feel they sound good, just was wondering if the sensitive volume knob when using them is a good "indication" that the amp is driving the headphones well....

Now you got me curious.....How would i do that, connect them to the speaker outs? that amp has old fashioned screw connections that have the bare wire drop into....
