What amp to choose?


I am running Infinity IRS Omega speakers and a 6 channel multiplayer equipped with preamps, by now I only use the 2 channel stereo. This a high quality gear MSRP USD20.000. The amp is a 150Wpc and 1800VA (240V/50Hz.
I run it balanced.The combo does deliver a good soundstage, detailed and I am satisfied with that.
I love my Omega`s,but they need more power and I want to optimize the system with a better amp.
Previously I`ve heard the player with PBN AX amp this is an option, sound is just right, but price new is to high for my budget, and I have to look for used.
I will be grateful if anyone could give me some inputs.

Phaelon thanks for suggestion.
JC1 collect rather good reviews, one pair at audiogon, but the price is to high for this pair though.
Do you think they would be better than Krell KSA250?
Musical Fidelity cut the price in half on their Supercharger 550K mono power amps, and that makes them $2499.98/pair new. They put out (as their name implies) 550 watts each into 8 ohms (and 750 watts into 4 ohms). Reviews that I read were raves, and stated that these are so transparent they relay the characteristics of the amp or preamp upstream. As "superchargers," they can be driven by either amplified speaker level or linestage interconnects.
I haven't been a huge fan of the Krells, but admittedly, I've only heard them a few times and none were the newer models. My suggestion was based mostly on the Halo's ability to provide effortless power to your Omegas. I just thought that it would be a worthwhile audition and that you might be able to find one used at your price point.
Well for a budget of $ 2,500 USD I would look at a pair if Adcom GFA-555SE new they are 1,100 - 1,300 each. I have 2 GFA-555 and 2 GFA-555II that I am using, all I have bought used from $250-375 each.

Have to make a cheching list, find my local dealers and just listen around.
My conclusion is that all the variables, different type of setups, gears, rooms...alltogether will not give a "correct" answer whats best!...for such a limited budget.
Reviews for all suggestion here is promising to the price limit.
Grateful to have more opinions.
