Not enough info man!
HT or music use, room size, receiver used, etc. will get you better info.
Welcome to the forum!
For what its worth, the Athena's have a loyal following.
I guess the Energy's do too. But my buddy has the Energy's and I dont think they sound so great. Seem light weight also. They don't really fill his room and it's not even that big. I guess that's why he is ready to upgrade as well.
Try to listen to both and decide what sounds best to you. That's really the best way to pick speakers. Everybody has different tastes.
Also, if you do like the energy's. Make sure you get a good price as they go on sale a lot, and my buddy paid well under $100 a speaker. Although, now he wishes he didn't try to save a buck and would've just paid a little more for something he liked.
