James, I had my 1.7's for a little over a month before getting the Mye stands.
The Mye stands offer greater stability over the factory feet. The struts hold the frame securely approx 2/3 up and the base has brass points. The brass points are adjustable to provide leveling or tilt back (instead of plastic factory spacers). The bass is tighter with more definition and punch while the mids and highs have better clarity. I recently added reptisand to the struts and got even more improvement. The reptisand (available in pet stores) reduces vibration in the struts and has helped dampen resonances that caused a smearing of detail. This in turn gives a sense of blacker backgrounds, better seperation of sounds, greater clarity with more nuance and resolution.
FYI, the stands are well built by a super nice guy named Grant VanderMye of Kelowna BC. His website is
