Agree with the USM but to add further complication there are numerous methods of even doing that. I always sharpen the lightness channel in LAB mode and then re-convert to RGB as to my eye you can crank up the sharpness with less of the artefacts and halo effects.

USM but in combination with Edge Sharpening. Gets my vote.

Changing modes will result in slight loss of data each time (and therefore quality of the picture).

To accomplish the same effect, try this.
USM in RGB mode then
IMMEDIATELY go to EDIT > FADE UNSHARP MASK
Choose the LUMINOSITY mode and adjust the fade effect (I usually use about 75%).

This has a similar effect to sharpening the lightness channel in LAB mode and involves no mode switches.
