Long XLR's: PAD Venustas versus Mogami


Does anyone have experience with changing a long Mogami interconnect with something like PAD Venustas? I'm wondering what the gains would be.

I'm currently auditioning PAD speaker cables (Proteus Provectus actually) and like them. I've read a lot about the PAD lineup, but don't know what the Mogami characteristics are (I don't have a 40' cable of something else to swap it with :-))

Thanks in advance.

Regarding the speaker spike suggestion...After messing around with spikes for many years I recently put Vibrapods under my smallish floorstanding speakers (wood floor). Sounds great...and I see more speaker manufacturers (and tweek designers) using some form of speaker "de-coupling" technology (like the Sonus Faber Amati Futura). Is this a paradigm shift?
Boston Audio makes graphite/steel tune blocks to be used under spiked speakers. Anyone tried this?
My experience with coupling versus de-coupling varies based on the room/floor/subfloor and speakers.

When I had my listening room in the basement with a concrete (carpeted) floor, coupling worked very well.

My current room incorporates a floating wood floor system and de-coupling works better in this room. I run Wilson W/P speakers mostly, but others as well. Though I am contemplating the use of a largish marble/stone slab for its mass/weight and placing the speakers on this. Have others tried this approach and what has their experiences been?
I spiked my speakers the other night to see what I was missing. I first tried it with the lowest setting but it produced way too much bass. Wilson provides spacers for this type of situation and so my next attempt was with both spacers (equaling the height of the casters).

With this I didn't hear much difference from the casters, but I did *feel* the bass more (concrete floor for what it's worth).
I have used the Adona platforms under my speakers. They are granite with a layer of MDF bonded to the granite. I used them granite side down and either set or spiked the speakers on the MDF side. They worked quite well.
