Thank you for the warm welcome, that is very nice. I will review the posts regarding ribbon buzz & selecting appropriate screws to minimally tighten, as well as humidity, although I think it is a low humidity situation indoors this winter–but humid summers in Northern Virginia. We tend to keep the windows open spring through autumn. What would be the benefit, if any, to running a hair dryer set to low heat & low speed from a distance, not close, over the buzzing area? Bad idea? Not trying to shrink wrap the ribbons like the window insulation treatments I put up in winter. Future plans: perhaps introduce the second M1.0T into the system, both set mono, driving their own speaker. I have yet to top-out the M 1.0T LED lights, so would there be any real sonic benefit? My guess is probably not. These, as I have learned here, are the non-inverting models so a flip of the switch on the back panel would precede a new hook-up. Still experimenting with the Sunfire True Subwoofer Jr. crossover level & volume. The ALS's bass is incredible, more so than in the past and I attribute that to room placement, having back and side walls walls not opening into another room or hallway. I have set the crossover at 35 Hz and the volume rather low and the low end is very nice. My wife said it is good to have Big Music (her words) again, meaning the sound & soundstage of the ALSs. I will post an update as things proceed. And to correct a mistake, that is a CT-7 in the system, not TFM-35. Thank you once again for the cordial advice and hospitality.
