Tiny bridges everywhere, but why?

Hello izjjzi. Cable supports are a great way to make money! Unless you're spending $10k per component, forget it. Try putting cardboard wedges under you speaker cables and be sure your health insurance is paid up. Tripping hazard! If the wedges improve things, leave them there! Some guys are selling a four inch block of wood for $35 bucks a pop! P.T. Barnum was right! Perhaps I went into the wrong business. Hmmmmm.

There is the odd blow hard out there that would have you believe you can make a $10,000 system sound like $30,000 with gum,tape, haywire, and a endless list of crap.
Doesn’t work that way. Put balanced components in a well treated room and enjoy. Save the dreaming for equipment up grades not Fantasy and crappy idea’s. 

mijostyn, if you're correct on that then Miller's ceramic insulators are no good either.

But if it's good to put magnetic material close to cables (and I'm not endorsing that) then why not insert them longways in a length of iron pipe?

DJones says..‘I wouldn’t spend much money or time fooling with cable lifters but it does make things look a bit neater. They do absolutely nothing to your sound so no need to worry they might cause a deleterious effect.’

Ordinarily true. I would say that most out there have no impact. But the Synergistic Research Cable Risers not only change the sound, they do so dramatically. The effect is very pronounced with the Foundation Series speaker cables but is also immediately apparent with other cables brands and types. These beautifully crafted (and expensive) devices are unlike normal cable risers and imo are really more akin to the HFT resonators placed on aluminium not-so-tiny ‘bridges’. These risers are quite large.  I’ve come to the conclusion that the HFT technology is responsible for what is going on because the effect is still there to one degree or another if the cables are removed off the risers but the risers are left in place around the speaker plain.

The question is not whether they do or do not change the sound. It’s more a matter of IF you like the sound with them or without. I was astonished at first at how much they changed the sound, and it took a while getting used to this different presentation. Without, the sound is more ‘relaxed’ shall we say. Imagine if you will the image as normal is somewhat soft, diffuse and splayed out wide. You might say ‘my system doesn’t sound like that’ until you put the risers in and hear what they do. Putting the risers in place is akin to gathering all the sound and bringing it in toward center. The sound becomes a lot more focused and the imaging clearer. It is not in the least bit subtle I assure you. The sound is ‘taller’ and less diffuse. This effect can be very enticing at first, but over time can seem a little hard. I do not leave the risers in all the time as i sometimes like to relax more into a slighty diffuse sound.
