You don't need a powerful amp for a near field listening setup. If you want something a little more powerful than the lepai, check out Topping.
Dr. Groove, in all seriousness, have you tried using the lepai and the topping amps? They do not work very well at all. It is not even that they sound bad, but rather than they start to break down very quickly. I have used two topping amps that died within a month and a lepai that had a very slow death and only lasted about 4 months.
Unless someone is just in plain desperate need of a very cheap amp, I would say to look elsewhere.
@OP: You said you are looking at speakers for gaming. How much music do you listen to?
If you are not looking for bleeding edge audio performance and you want to save a decent amount of money, I can say from experience that there is nothing wrong with the klipisch pro media 2.1 or the corsair speakers.
If you would be willing to consider a better set of speakers with out the sub woofer, then you can get the audio engine A2s or the KRK rokits http://www.sweetwater.com/store/detail/Rokit5G3?device=c&network=g&matchtype=&gclid=CMCikqqGpL0CFewDOgodPVEAFA
Like I said, if gaming is your main goal, then there is nothing all that wrong about PC audio. Anything you get is going to be a pretty decent upgrade over logitech speakers. The only thing I would suggest that you do is pick up a sound card or maybe a used audio engine D1 so that you are not using the crummy realtek on board audio.
