Modified Lenco vs TW Raven

Hello,
I have a TW Acustic Raven for a few years now. I made different upgrades along the last 3 years : new battery PSU and 3 motors in a round shape. I was thinking about the last upgrade (for me) : the BN platter and new bearing when I heard for the first time to modified Lenco by TJN. I read most of what there is to read for a non DIY, and there is a lot...
Before deciding if a make the jump I'd like to know if some in the community have made the same decision : I mean going from a top belt TT to a top idler wheel. I think of the ref models from Jean Nantais and tell me if they are happy now.
Thank you for helping

Gilles, What "alloy" did you use for your plinth? That sounds like an unusual and interesting choice of materials, compared to the more typical woods, slate, related synthetics, or even lead.

Barbapapa, I have a WAV24 file to which I can give you access and you can judge for yourself. I use a Tascam DA3000 for the digital recording. Just send me a PM and type of music you would like to hear.

To Lewm, the plinth is in massive aluminium.

Here is the beginning of the story.
After this, he has made a prototype in aluminium that I bought,and has finished with a 400 pound turntable with a 220 volts engine for maximum torque, but belt driven.
The fundamental philosophy is maximum weight to kill vibes, no damping and feet to drive vibes out of the plinth.

You should checkout the Artisan Fidelity Lenco's i have one and love it!! He now is putting inverted bearings in them and the workmanship is the best in the business.

Gilles, The plinth in the photo looks to be made of layers of MDF, not alu. However, Jacques does mention that he is going to build one out of a solid block of alu, which must be the one you bought(?)

FWIW, I really really do not like the sound of any of the many all-MDF plinths I have heard. For me, you either need layers of alu or layers of baltic birch, intermingling with layers of MDF, to get a neutral sound. Just my personal opinion and experience.
