I wonder if anyone has experience with both stands in regards to stability and quality? I just installed a pair of Sanus stands for my new ONE speakers in my 5.1 Sonos system. They seem stable and of high quality and I was impressed with their customer service. My dealer was supposed to send my two Play 1 speakers with the 5.1 system and hence i ordered a pair of Play 1 Sanus stands. Unfortunately, they are incompatible in that the ONE does not have the screw fitting on the rear as does the Play 1. Without hesitation, they sent me a pair of adaptors at no cost to me. Impressive! Having said that, the base on the Sanus stand for the 5 seems a bit small in comparison to the base of the Flexson. Trying to decide which pair to order and any guidance would be appreciated. I see there on the Sonos site, they sell only the Flexson model.
