Hey, congratulations!
Ribbons tend to be a bit hot in part because they have such good dispersion -- their power response is flat while the power response of a dynamic tweeter is rolled off in the treble. And most recordings are mixed/EQ'd with dynamic tweeters.
A bit of HF absorption (drapes, carpet, etc.) in the room can bring the HF balance to where you like it. IIRC Magnepan's recommendation is that if you need more than the 1 ohm tweeter attenuator to bring it in to balance, you should add absorption.
Also, the IIIa's are flat speakers rather than down-tilted ones, as you can see from the in-room power response in the link below. Some degree of downtilt, maybe 4-6 dB across the entire spectrum, is usually preferred with two channel stereo when playing large ensemble works, presumably owing to the fact that the mics don't pick up as much of the HF-attenuated hall ambiance as the human ear. Again, something that can be achieved with some combination of room treatment and tweeter attenuation, or with electronic EQ.
