Audio output match?

Plan on running audio output from laptop into high impedence amp input. Do I need to add a 10-20 ohm resistor to the laptop output to represent the normal earphone/speaker load?
Or is it ok to run directly into high impedence input?

I was asking if the audio output from the laptop needed a normal speaker load. Would it damage the audio output from the laptop to run into high impedence input.

Thanks, In the past I had used a 10 ohm load resistor, but making another interconnect cable and wanted to leave out the load resistor and go straight to the high impedence input.

If your laptop uses vacuum tubes in its output that feed a matching transformer then it needs a load. If it is solid state then it works even better (lower distortion) with a high impedance load.

ok, I am from the tube era, but my laptop isn't:D
thanks

Some people like the distortion caused by a vacuum tube amplifier and its lack of damping of a speaker's resonances.

Perfectly OK, it's how it's designed to be used.
