My Niagara 1200 sits behind my couch on the floor, wall to wall carpet. That is where it will remain. Suffice to say I think it is stupid to think you could possibly perceive whether it is supported by spikes or hemispheres or cones or whatever....I'll go with expectation bias. It's a power conditioner, nothing more. Now, a turntable or cd player? Well then, yes I believe you should spend time getting those isolated/supported properly.Do you think it's stupid that it came with footers already in place as well as more to be used in case you were to place it on its side?
Do you think it's stupid to believe it is immune from vibrations?
Do you think it's stupid to be so intellectually lazy as to fall back on the expectation bias meme?
All the best,
Nonoise
