I stuck "vibra pods" under my speakers on wood floors and they sound amazing...this was after decades of spikes, and it seems that some high end speakers come with what they call "decoupling" dampers so there could be a trend away from spikes...for room treatment you can also try buying thousands of pods and stick them all over your walls and ceilings, but I find that hurling large amounts of freshly cooked pasta against the walls works well, although you have to keep at it as it dries out and falls off.
from w/w CARPET to WOOD floors
I am thinking about pulling up the wool berber and thick pad underneath. My thought is the carpet/pad can suck the life from the music in much the same way too much absorption can. Then I would use an area rug, and take absorption baby steps if needed. Please share any thoughts!
