What to drive Soundlab Prima speakers with?

I am currently using a Llano Trinity 200 to power a pair of Soundlab Prima speakers and find that the bass just isn't what I think it should be.  Just a little background:  I had a Llano Trinity 300 that was driving Soundlab Quantum speakers and it sounded amazing.  Trinity 300 was damaged beyond repair (long story) and I switched to my Trinity 200 to drive the Quantum speakers and it sounded great.  Fast forward to today:  I picked up a pair of Prima speakers after I listened to them being driven by Joule-Electra VZN-100 OTL Amps.  As you can guess, I was blown away by them compared to the Quantums.  
So my main question is what to drive the Prima speakers with that won't break the bank?  I was thinking a pair of Adcom 555 II amps each bridged.  Are there any other monoblocks out there that aren't big money?  I wanted to stay under $2k if possible.  I know that isn't much, but we just moved, spent a ton of cash fixing the previous house and buying furniture for the new house.
TIA for your input!
