Thoughts on my current system

Adiorio, 
 I agree with what most every one is saying here. I cannot stress enough the importance of starting from a Strong Foundation to build on. It took me a long time to wrap my mind around this concept and I wasted tens of thousands of dollars through the years figuring it out.  In order to get the most bang for your buck you want to make sage changes that move you forward not side ways. It will take a while.

Keep the components you have, set up in the new room. Start by Investing with Power, Power, Power. Think of your power distribution as the main component in your system. You want to maximize the performance of all of your components together through a maximized power delivery system. Get a great power distributor, not conditioner. There is a Weizhi on Agon now, they do not come up often. Oyaide makes an excellent one as well. Look to Oyaide R1 receptacles rather than Wattgate. There is also a pair of Thales Speaker Cables also rare on Agon. Their Interconnects are best in the industry for the price. Take advantage when ever possible.  JPS, makes good power cords which you have,  Analysis plus Oval 2 also very good, Regular Ovals even better.  

Once you get the power sorted out then look to methodically change up your components.  Educate yourself on the companies that build the components, speakers etc. You want companies that are dedicated to building great products that you are spending thousands on. Start with your CDP. Exogal, the old Wadia team is doing some interesting things. Sonus Faber speakers today are not the same company they were years ago. Older models are  better. Also Check out Devore, there are a pair of Silverbacks also up on Agon.  Your ARC Pre Amp is better than most builds today, but Rogue Audio has great products, maybe a better option when you are ready. 

When you get the components that you are happy with, then start on your tweaks.  Good Luck

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.
