With a good amp, I think the ammount of power is less an issue. I'm not sure how much power you think you need for your system. Lower power does not mean 'poor sound quality' and by the same logic, more power doesn't mean 'better sound.'
I owned an Aragon 8008st and found it to be a very good sounding amp. I replaced it with an amp that was the same 'on paper' but the sound quality was vastly superior. I bought a Krell FPB 200. Both amps are rated at 400wpc into 4 ohms, but the Krell is hands-down better!
BUT in your situation there are some issues that must be resolved. How hard do you drive your gear? What kind of music are you listening predominately?
In my opinion, buy the 4004, or if you can swing it get the 8008. The reserve power of the bigger amps will allow your speakers to reproduce those sudden attacks in the music that a lesser powered amp will not have available. Unless you are only listening to old presidential speaches you will appreciate the power reserves.
I hope I did not ramble too much. Sometimes thoughts are not expressed as clearly as one would intend.
Good luck, Aragon makes nice amps, and the 4004 should be a nice upgrade from the Adcom.
