Dear Halcro/Raul
Some impressions - Having had this setup going for a few weeks now this is what I believe has happened in laymans terms. Bear with me.
We all know the needle in the groove moves back and forth, causes good vibrations to happen, which are then picked up by the stylus and sent down the phono cables along the tonearm to the rest of our gear to make beautiful music.
Any other vibrations that get introduced into play are bad, a problem, and we hear that as distortion in the music itself. Other vibrations come in from at least two directions. 1) Up from the platter into the cartridge, down the arm as well as 2) up from the plinth, up the arm pod where they meet with the other vibrations and cause the havoc we hear as distortion.
I believe I have reduced vibrations going up the platter with this setup - but MORE SO going up the arm - by isolating it more.
Further - A plinth is by definition any structure. I still have a plinth that my sp10 and arm are coupled to. Its the 4 inches of solid maple. It can be seen in this link.

Both sp10 and arm board are coupled by spikes they are not on separate audio stands and the sp10 itself being plinthless.
The above is why I believe I had improvement in sound. A fantastic plinth that the DD and arm sit directly in or on will also reduce both direction vibrations but this is a much more complicated solution and costs a lot more $$ to implement to get to this level. I believe it also introduces colorations to the music itself as it has been said by you before based on the material used. This setup is much more simpler to actually implement and for the average guy or gal me that has a good DD TT the isolating of the arm got me to a place that would have cost me much more $$ to implement the other way.
Does this reasoning make sense. It has been said before I realize but I wanted to put in simple words for others implementing this setup.
I wanted to also mention that having this setup reminds me of computers Desktop versus laptops. Heavy plinths are like desktops and rarely moved if at all due to weight and their structure. This set up is portable and can be moved very easily. This is a big + as I have 3 systems in two physical locations. This has allowed me to enjoy my vinyl in multiple locations.
Final thought is that I have been experimenting with different feet for the sp10. Currently using mapleshade spikes. I find it very easy when setting up to first - put the arm where I want it to be and then 2) just move the sp10 into alignment rather than messing with the arm. It takes about 3-4 minutes to line up the ET arm once I have changed feet.
Thank you for bearing with me appreciate the feedback.
Cheers - Chris
