Does raising speaker cables off the floor really make a big difference?

i still have my 4 bose 901 series 2 from the 4 chanell days. i have a small living room so i have all 4 hanging from the ceiling! compared to when i had them on stands and now hanging from the ceiling, i can't hear no difference!

Honestly,  I have no idea as to whether or not there is a tangible,  sonic benefit from raising them off the floor,  but all of the techinical and scientific evidence I have consumed says that it is a good idea.  So I do.  It just makes sense to me.

I also use platforms for my equipment,  never stacking one piece atop another like I did in high school/college.  I read about vibration affecting sound in negative ways,  so I bought platforms. 


These are the most simple "tweaks" one can employ for attaining better sound, and they're pretty cheap.

I was thinking about trying SR UEF Cable Risers next. I found the SR Blackbox sucked the life out of recordings by cutting off frequencies above 8Khz. The UEF Cable Riser demo https://www.youtube.com/watch?v=KVIKxulyLNY may indicate a similar negative loss of highs/openess effect using a type of ECT on each riser, or they may just focus the sound better without losing the highs and openess.  I will have to try it in my listening room to see if it's a keeper or a loser.

  The audio mag writers who witnessed the demo with the Synergistic cable risers said they made a big difference sound wise with them in the system.
   Can you report back if you try them. I would be interested in your comments.

I spent an hour on a simple study. Googled RMAF and a few others to look at pictures of the rooms with equipment I will never be able to afford. Many had visible risers to get the cables off the hotel floor or had taken steps to eliminate ground contact.  I have learned that the most important thing besides actually practicing critical listening, is keeping an open mind. The third best thing is to ignore those who post multiple times in one thread to prove they are correct.  A ten dollar investment in what will surely not "hurt" anything is a fine idea.  Not taking yourself too seriously and being able to laugh is also a fine idea.
