If you know of anything else please do us a favor and post here. Thanks.

Check my post here: Review of Little Dot MKV Dual Mono Solid State Headphone Amplifier It may be over simplistic, but it does get results. I have received positive feedback from owners on all of the types mentioned.

Afraid that wouldn't help with the computer source induced noise. If amplifier and PSU are in one case, USB or coax connection from computer transfers all internal computer noises using this connection as a conductor closing the ground loop. Out of everything I have tried 100% elimination is guaranteed by one of the following:
1) running laptop source off the battery
2) using xitel ground loop isolators (other brands will do to I guess)
3) adding 3 to 2 prong adapters to power cords with separate ground pin.
4) switching to optical toslink or using wi-fi as a transport.

EDIT: Actually that Ebtech Hum X | Sweetwater.com sounds like a thing to try, any idea what's inside.

Interesting info on Ebtech Hum X
Ebtech Hum-X: Harmony Central User Reviews
Seems like it's not UL certified, but nonetheless is probably safer than just plain cheater plug.
If it only worked 100%, as based on some user reviews it does not eliminate 100% of the noise.

Another one. 75% effective?

So, you are talking about Desktop computers then?

Sorry, I have no idea what's inside, but several owners have given it praise here.

Agreed, I'm sure its safer than the cheater plug. The reviews here so far (that I have seen) say it does an excellent job. I suppose this could be one of those "what type of user" things. I've been pretty lucky so far, and haven't had a need for one... Knock on wood!

Wondering if anyone here tried it. Can you please post links to these review, somehow I cannot find much Ebtech related posts.

I've tested the Behringer unit against the Trends UD-10 and The Trends Audio unit sounds so much better. The Behringer does a good basic job without problems and at 30 bucks is a good deal. The Trends Audio UD-10 was a real surprise. It's a huge upgrade from the UCA-202. The '202 sounded completely flat in comparison here.
