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.
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?
