Computer Vs, Stereo Vs. Empeg.

I am sure by now you are all getting tired of my endless chatter and questions so I'll go out with a bang. I currently have a Empeg player 60G works great but I was checking out some of the new audio gear and I raised some questions again.
I spent two hours trying to convence my friend that empeg was the way to go but with no good hard facts I failed, in fact now I am not sure which is the way to go, all of the options have there Pros and Cons
Looking for some UNbiased input and I am sorry but "because" is not good enough if you could post some good hards facts that would be great.(I swear this will be the last time I ask this) The Cost is not a huge issue for me but I find it hard to swallow a 500 bill to fiberglass in a screen and I lack the ability to do it myself. all of the soultions are in the same ball park and I could sell my empeg for 400 easy so thats not an issue.
Please don't hate meI am just looking for input, before I drop 700 bucks to upgrade my empeg and get a DEQ.
