Do we believe in Machina Dynamics?

Nope. Next question...

I imagine there are many who find some MD tweaks work and many who would never try them, and even a few who try them and find no benefit. One thing is certain on the MD tweaks as well as the Acoustic Revive tweaks, we get little inclining about why the work. Lacking this many will not try them, others will. There is no concensus nor anyone really available to convert to one position or the other. In short the discussion is a waste of time.

Be certain to buy matching Timex clocks and matching orange price stickers so the study participants don't know which is Machina Dynamica product and which is not. Same with the jars of pebbles.

Same with the $30 "Tru-Tone" Duplex Covers that you could purchase at Home Depot for $5.97.

Same with the "Special Helical Springs" that you could order on the internet from a hardware supply house for under $10 (although, addmitedly, they might not be "special" -- at least in the way MD means it).

Their physics are no less sound than those behind most tweaks and cables and they have smarter guys coming up with product names.

Drew: With respect, their "physics" are widely regarded as a joke (or worse) and have been debunked all over the internet. Try a google search of any of Geoff Kait's "white papers" and you will see what i mean.
