Thiel 3.6 and 'grounding' / insulating


I have a lovely old house with hardwood floors. I just bought a pair of Thiel 3.6. I plan to use the stabilizing pins / spikes provided with the speakers (probably put the spikes on quarters or something). My question: would it be worth my while buying a pair of thick (2 inches or so) granite slabs to put under the speakers with the spikes? Has anyone tried this and if so, what were the results? Thanks.

Pvanosta I know your money will drasticaly be better spent on Audionpoints or better yet Sistrum Platforms. These devices will allow the cabinet resonance to leave the cabinet and shunt to ground. Placing the speakers on stone or marble is not going to dissipate the cabinet noise, it will only move it to a different frequency range. When cabinet noise is drained away you will hear a much more focused soundstage and one that is larger and quieter. Bass will become more extended with more weight,all the while being more tunefull. I have friends with Thiels, B+W's and Paradigm all were blown away by the improvement they heard by adding these devices. I have been using Sistrum Platforms under my Dunlavy's for 3+years now and would not bother to listen with out them.
Thank you. I will look into Audiopoints and Sistrum Platforms. I appreciate your input.
Mine seem to sound better 8 feet apart as opposed to 5 feet apart. Toe in mainly if your are having problems with early reflections from sidewalls. Did you try the Sistrums? I'm curious about those devives after reading the thread. I just got my 3.6s on 12-4. Quite a step up from the CS 2s I had been using since 1985. I think I need better electronics now...sigh.
Just curious Pvanosta, what is your amplification? I will say in my experience with my 2.2's, speaker cable of a heavier guage does work best for the bass, but only in terms of tonality, quantity, dynamics, and extension - lighter guage cable will just shortchange the speakers and give a thinner, less developed sound. The bass being somewhat 'loose' is probably a function of the amplifier chosen, and the 3.6's with their larger bass driver and radiator, and lower impedance dip, are tougher in this regard than mine. Since you don't mention it, I assume you don't consider this to be a potential culprit though, but then again there are many 3.6's out there in the world which are not partnered with truly adequate amps (or cables).
Pvanosta, I've had 3.6's for about 3 years now and find Goertz MI2's to be a nice match, Thiel does also. These cables give a more fleshed out, full bodied presentation in my setup. Also these speakers respond to every inch you move them which can be maddning. I currently have mine 9 feet apart and about 4 feet from the front wall and 3 to 4 from the side wall - which allows me to point them straight out with no toe in. This gives me a very wide seemless soundstage - the speakers also sound more open, less boxey when placed further apart - but YMMV
