Thoughts on my current system

the amps were filling in for a Pass X250.5 which was in for repair. I found the Odysseys to be a great bargain...

how about a jl audio fathom f112 or f113 to add some punch to the lower end

Adiorio, 

I do not have extensive experience with the amps you have. When Mondial first producing the Aragon, I did consider getting it. I liked the build quality and the look. I ended up falling into a fantastic deal on some Conrad Johnson Units that I could not walk away from at that time.   

What I have come to realize over the years is that it is more about how you match the electronics together and how you get there to accomplish your goals.  The Aragon you have has a dual mono amp configuration with a very solid frequency response. I suspect that there is not enough power getting to the amp to realize its full potential. It's like having a mid century muscle car that you only use to go to the grocery store. It's built to go
120 mph, when your only going 35.

Like you, years ago, after the CJ's - I had an amp that I was generally happy with but was considering getting a larger amp to get more.. everything.  Every Audio buddy/salesman was telling me yeah get this or that. Spend More $$$ ( a sideways move)  - I was fortunate enough to meet some one who explained to me, its not the amp, its the power.

I always knew I had to address the power issue, but had only done a half ass job of it because honestly who wants to invest that kind of money into something you can't see. How sexy is a power cord compared to an Amp.
To prove his point he loaned me one power chord that cost as much as my mono block Amps. I plugged it into the wall socket and then into my power distributor. I could hear the difference in the first 30 seconds. It took over the entire sound stage and opened up everything!!!

Instead of spending more $$$ on new amps I got new power cords, interconnects, speaker cables and power distributor. I have spent as much on power distribution as I have on components and speakers.  Eight years later I still have the same amps and speakers. That's not to say I have not considered up grading, but now I know for sure that any component or speaker that I consider I will get a true reading on. 

I concur- ggc

power cords are essential- one has to find its inner synergy to mate w/ the other gear in your system.
