Suspended cables

Hi folks,

Still a bit of a newbie here.

I have gained an understanding of the reasoning behind keeping speaker cables off the floor.

So ...,

Each of my mains have a 1.5 meter cable connected to it’s own monoblock. The monoblocks sit 26" above the floor and nearly level with the speaker terminals. Speaker to monoblock distance allow the cables to be suspended completely from the floor in a loosely hanging arc (about 8" above the floor).

Is this better than using cable risers?Β 
Are there any reasons not to do this? Stress on connectors? Bad for cables?

Thanks all!
