Looking for a new power amp - choosing between T + A, Atoll, Rogue

Your Audible Illusions preamp is stellar and definitely worthy of your speakers.

I would go for the Stereo 100 Dark over the DragoN. I really like Rogue’s full tube products but never been impressed by their hybrids. 

Personally, I would probably even take a Cronus Dark over your AI preamp paired with a DragoN. 

Based on the description of what you’re seeking, the Stereo 100 with your AI preamp would be a great combo. 

If you’re set on solid state, the Parasound JC5 is very full and musical. Like other JC designs, its distortion profile is 2nd-order dominant, and therefore, uncommon among solid state and almost tube-like. 
 

Clarifications:  All equipment is broken in.  I've had all components including PMC speakers for at least a few months.  I'm in a small market, and my dealer carries all three product lines (Atoll, Rogue, T + A).  But he doesn't stock the models I mentioned.  So I have to purchase based on reviews.  I've heard my equipment with a lower-end Rogue and lower-end Atoll, and with the T + A M200 mono blocks (higher-end than I'm shopping).  I loved the sound of the T + A, but obviously it was not a fair comparison.

@ghdprentice - are you suggesting that I should up my price-range?  I consider the speakers high-end; I actually like them better than any of PMC's consumer models, and am looking at them as my final pair.  I want to do them justice.

If you want to optimize your speakers to gain the most out of them then you would want to optimize your whole audio chain. Yes, I think your speakers would benefit from an audiophile amp. Used can get you into that category. So, you don’t have to increase your budget. Most of the stuff I would recommend is over $10K new. It puts you in a place where all aspects of the sound are really well reproduced. 

Then you’ll need to look at your DAC. For long term planning purposes I look at 30% speakers, 20% amp, 20% preamp, 15% DAC and 15% streamer. Having a really solid performing preamp and amp will set you up to get the most out of any input. Of course this is just a generality. I have gone much higher on electronics and got much more out of a pair of speakers than you expect. 

There are some good recommendations listed. The only area where I would disagree is going by price. For example, if you have a $5000 budget for an amp, then you're going to buy a $5000 amp. Do all $5000 amps sound the same? Not even close. I would focus on finding the right amp. Not one that fits a price category. If it turns out that whatever amp you pick is out of your price range, you at least have a reference as to the type of sound you are looking for. And sometimes you get lucky, and like a cheaper product instead. If you live in the US, there are some pretty good non local options if you would consider other brands.
