Caster Wheels vs. Spikes


My Tekton Double Impacts came with caster wheels, which made them very easy to move and reposition. They are sitting on probably fake wood floors in my apartment. They sound great now, but I can't help but wonder if I'm leaving SQ on the table by not having them on spikes. Some people say I must use spikes, others (including Erik Alexander) say wheels are just fine. They are super heavy so the wheels are not easy to take off. I want to make sure it's worth doing. What are your experiences and thoughts?

Oh, you are SO losing out by using casters! The difference is OBVIOUS. No true audiophile would use casters! Once you hear spikes you will NEVER want to go back! 

Hey, wait! I put casters on the Vapor Audio Joule White speakers! Nevermind.   ;) 

No one here has figured out the most important variable between spikes and casters. 
Have soundocity make outriggers for you that will fit your caster wheels to position then get the screw in from the top threaded spikes once finally positioned. 
Swiveled plastic wheels are working great for me on hardwood. So easy to position depending on where I’m at in the room. I lock the wheels with than pointed out at the corners, give the speaker a little shake to hear the wheels lock and it feels pretty solid if trying to move the speaker.
Great way to experiment with the sound/position!  And fairly cheap. 20 some bucks for a set of 4
Well to complicate matters, besides spikes and caster wheels, there are Isoacoustics Gaia feet. I used Isoacoustics Gaia feet on my Magico A3 pair. Magico provides spikes. They are make A-Pods which are spikes with isolation tech built in. I didn’t want to use spikes for these, because my system is in a dual purpose room and the A3s weigh about 100 lbs each. I was afraid that I might walk by and inadvertently brush against a speaker and knock a spike off its pad. Possible disaster might ensue. So I wanted a more stable footing.  I chose the Isoacoustics Gaia 1 feet and I have been please with the stability and the SQ. 
My speakers weigh about 70 pounds apiece, and are on heavy duty Berber carpet.  Since I frequently move them from a whole room, straight out listening position, to a toed in home theater listening position, I put smallish heavy duty carpet sliders on the four corners.  This makes for an easy move, and the HT position is marked in tape for easy re-positioning.  To my tinnitus addled 62 year old ears, no difference in SQ was detected.
