I’ve seen a different Alta Audio model (which I enjoyed enormously) at an audio show and they had them toed-in just a little bit. Here’s a link to a YouTube video with the Adams, again toed-in just a little bit; conversation with the designer starts around 3:00. If there is anything amiss that correlates with the Stereophile on-axis curve, it’s apparently below my detection threshold:
They don’t strike me as designed for time-intensity trading; that is, axes criss-crossing in front of the listening position. So my instinct is that little or no toe-in would probably work best.
