I don't think the amps are a good match for your speakers. You need more efficient speakers for them to perform at their best. See the link below for some info on the amps:

A couple thoughts - 

I am not familiar with your speakers. I run 93 dB efficient JBL monitors with less than 8 watts per speaker and they have loads of bass, but they are using 15 inch woofers. 

I think the suggestion to play around with the positioning of the speakers is a good place to start.

Good luck and please share your progress on your journey.

I see the problem. You have no bass. Throw a good sub (or two) on your system, it will be a new world. 

Paradigms while fairly efficient are not an easy load. IMO and IME you are waaay underpowered for those speakers. What version are they

What they said. More power needed. 2A3 amps need big drivers or horns. I'd bet they're 90dB.
