You should tell Nelson. He is easy to contact and almost always responds.

Funny how that works!
Yep, I had a similar experience, Glenn, when I put my REL sub on A/V Roomservice EVPs from Norm Varney. The EVPs prevented the sub from coupling resonant energy to the floor, which then couples to the "dry wall" walls. And, dry wall resonates at...70 Hz! So, it's very audible. The EVPs brought a significant improvement because they made the entire room quieter. 
Altaira brings similarly profound improvement in the reduction of ground-plane noise from our components and devices. Many "digital-domain only" devices (routers, switches, computers, NAS, network bridges, streamers) are often very noisy, as it turns out. The ubiquitous switch-mode power supply is particularly nasty villain in this "good guys vs bad guys" play...
