I have been thinking for a while about what makes my support for my Sondek work well. Here are some thoughts:

I have realised that my support for my Sondek goes from rock steady (my heavy metal shelf), hard suspended (the small rubber feet under my rubber mat), medium suspended (the pockets with the plastic legs placed within) to soft suspended (the feet on the Tramp1).
My guess is that this gradually differentiated suspension is filtering out bad vibrations that could influence the spring suspention inside the Sondek.
I can feel a gradual decrease in vibration from the metal shelf over the light Audiotech shelf to the Tramp1.

My guess is that if anyone could make a finer graduation with more levels we would end up with a monster sounding Sondek. :-)

I guess two importent ways for vibration to get negative influence on the pickups decoding of a record is via the tonearm cable and via vertical vibrational disturbance from what the Sondek is placed upon.

I feel that looking at the Sondek the Trampolin (1 and 2) are a pitstop towards the final goal. However small they will reflect something back towards the vital parts of the Sondek making a loop of disturbance inside the Sondek.

All speculations of course but on the basis of observations.

Hi Beck

Really pleased you're happy with your arrangement. I'm not a fan of the trampolin 1 used on a light rigid table like the SO I use. I tried one many years ago and didn't stay long on my LP12. Much preferred the old type base board or no base board at all.

These days I'm using the newer solid base board that comes with the Majik LP12 and I'm really happy with it. Quite a job to remove it and put it back on the deck whenever you need to do anything inside but it's worth it IMHO.

Cheers,

Pedro

Important about my setup: Tramp1 is loose. No screws are used to make connection between it and the Sondek.

IMO, a good description what the Tramp does gives this article from Neil McBride from the time as Klout was the best Linn amp:

I agree with the above. I just think that even better working conditions for the pickup can be reached if we work outside of the constraints of the actual turntable.
