Cheap tweak from Virtual Dynamics:

Good point, Seasoned.

USblues - In da middle, and mine is cal'ed by a friend who works in a calibration lab.

Also a good point about messing with $$$$ speakers too. I plan to start with TAD 805. With the Tanto speakers I will walk the torque setting up to see if any turn, and might leave them alone, depending on what I see.

less to do with resonance and more to do with being non-magnetic. Be very careful with MDF as it will not tolerate many screw swaps before it is stripped then you are up the creek

Springnr,dat would be da place.Nice to have a friend like that there....the Snap on people were 50 or so and that was 10 years ago.....yeah,its just so easy to get into trouble unless your somewhat hip to that.Kind of like trying to take out scratches on soft metals or acrylics/paint etc.It can be done,BUT........

Well, I guess I'll be the first to be in line for flames from the other side. I initially equally torqued all my stock screws to the same 8in.-lbs. Soundstage appeared to be a little cleaner and a tad more focussed and centered. Nothing really revelatory. I then put the brass screws in one speaker only. I'll be danged if that speaker with the brass screws didn't suddenly sound a tad louder with a cleaner, crisper sound than the other side. Since I have small mini-monitors, I swapped the speakers and sure enough, the brass-screwed side sounded better. I listened for a while to make sure what I was hearing wasn't some subconscious desire for the sound to be better, then I put the brass screws in the other speaker. Sure enough, the other speaker matched the first with brass screws. I can say that this isn't a night and day difference, but the whole soundstage sounds a bit taller now and wider and deeper. Depth seems to be the most improved. The overall sound is a bit cleaner with better transient response. To my ears, a very slight haze or veil has been removed. I think I'll leave the brass screws in for a while.
