It takes 2/3 swipe left or right to turn it on/off. If you accidentally touch it or swipe it too fast, it won't work. This is a safety precaution.

Within 5 seconds, you can tell that Ref 18 effortlessly drive the speaker with speed and power.
Everything is relative in high-end audio, Ref 9V3SE is incredibly fast and dynamic but Ref 18 takes it to the next level. This is mainly due to the improvement in the new Cross Matrix Capacitor Array design in Ref 18 versus the Linear Capacitor Array in Ref 9V3SE. The bigger chassis with extra shielding helps too.
Ref 18 gives you the ability to upgrade to $10,000/pair Ref 20 (no release date yet).
Both series will advance together in technology development and future upgrade is always very affordable.
