Jeff,
I'm using the 3.3's myself, often for long periods. Bi-amping does more for these speakers than any I have owned. I can't express the difference in words. SPL is one issue relative to power output. But along with power, comes CONTROL of the drivers. If you have the duckies, I would suggest another pair of the monoblocks you are using. Not only will you get a bit more volume, but the amps won't be exhausted at the extreme end of the spectrum, which seems to be the arena where you lack satisfaction.
The NHT's (especially the 3.3's) are very unforgiving of non-neutral or excessively bright electronics and recordings. I used a BAT VK3i for a short time, teamed with Sunfire 300's (Biamped) with glorious results. I've since moved on to home theater. I'm still using the 3.3's biamped with Anthem MCA II's, and SS preamp/ processor. I've been unable to capture that same "magic", but the system still sounds great.
The 3.3's are VERY power-hungry. You know that. But the more juice you feed them, the more "open" they sound. It sounds like you've got them set up right. Moving them slightly away from the wall will improve the soundstage slightly, but you will lose some of the impact of your lower octaves.
The next upgrade I would suggest would be cheaper, and far more noticable: Replace the subs with a servo-controlled beast or 2. I've got a PAIR of Mirage BPS-400's, and find that they definitely add a little more slam to the flat sound of the 3.3's. I haven't used, or been exposed to, the SUB TWO, but the fact that you're crossing over at 60Hz leads me to believe that the 3.3's aren't being used to their full potential. An extra pair of amps would help you push the envelope. Let those 3.3's sing at full range, with the power where you need it. The subs can supplement the 3.3's when necessary. I find that my subs are unnecessary for music, but add that extra kick for home theater use.
Best regards.
Happy Holidays.
David.
