Agree with slaw.
Not sure if you're using both sets of speakers on the front at the same time and if so... Why? Also don't think they require that much power to start with.
Pro amps for home use are harsh sounding. I'd stay clear. Musical Concept mods do help Hafler's. I've heard a ton of Hafler preamps and amps and really never understood those who mod the heck out of them. They were ok back in their days but they don't compete with newer designs even modded.
I remember and have heard the NHT 3.3s and they are a pretty good speaker honestly. Recall Corey Greenberg of Stereophile loved them back in the day. I'd look at selling the Infintys and your Hafler's and using that money to buy an Aragon 4004 and spend the money you were going to spend on mods buying a nice little turntable. Greenberg used that amp on his 3.3s and I've heard the combo as well; it will rock and play plenty loud.
In your 20's? Don't fry your ears playing too loud as when you're older in your fifties you'll want to still enjoy you have good hearing. You buy a better quality amp with a little less power you'll find you won't need to listen as loud. You're system sounds too complex unless I'm just not understanding how you have it set up. Get a single 4004 and you won't need to bother with bi-amping and etc.
Good luck
