I bought my speakers and set them up. The basement floor was not flat so the speaker could actually rock. They only came with furniture tips that are just driven into the wood. I didn’t know much. The isolation topic was very common here and usually contentious. I went the cheap route. I bought 16 of the Audiokrast springs. Wallah! They are self leveling. The improvements from the isolation springs was very positive. Cost $120 for all.
All other components are sitting on Herbie’s products.
My audio stand is on spikes sitting in disc’s. I have not looked into anything else. I don’t like swapping parts or components all the time and the sound is nice.
