An answer to a question you didn't ask

Hi Neo,

Here is a suggestion based upon my personal experience. It looks like you have two turntables placed in the left corner of your room, one being directly in the corner.

Because of the buildup of bass nodes in corners I discovered improved clarity by moving my tt away from a corner. That cartridge/stylus are more susceptible to air-borne energy than we might guess.

If you can't move it to a side wall maybe you could shift it to the right and place one of your LP cabinets in the corner? At the same time, it looks like both of your tables are in line of the rear wave of your LC speaker. That may add to the issue.

Admittedly it would take some effort to move things around but at least that will cost you nothing by time. ;^)

Some good ideas. The table in the corner is a Linn Sondek and is really not being used. It might surprise some but the other table, a Denon DP55-K (direct drive) outperforms the Linn. Both tables have Magnepan Unitrac I arms. Changing location is really not in the cards, but do you think lowering the dust cover during use would minimize the transmitted vibrations?

    First off, I'm not an engineer so take my points with that perspective.
    
    In all my years in this hobby I've mostly played my tts with the cover removed. One exception was a Kuzma Stabi which had a hinged, very heavy oak frame with a plate glass top. Otherwise I agree with G Squared.
    
    While a dust cover may seem like it protects the arm/cartridge/cantilever from air-borne vibrations, I suspect it may instead be a transmitter for them. Being larger and more flexible than the arm/cartridge/cantilever my guess is it may "gather in" vibrations which it then transfers mechanically to the whole turntable assembly. But I can't reference any studies on this.
    
    All I can say for certain is moving my table out of a corner improved the clarity, and even that experience was with the Kuzma with the very heavy lid.
    
    Said another way, look at all the high end tables from $5K to $100K or more. How many of them include a dust cover intended to be left in place while playing?

      For the same reasons we eschewed box speakers we don't want dust covers on while playing.. If you don't want to remove the dust cover then you need to damp the cover.
      
      My solution is to glue viscoelastic foam (like memory foam mattresses) to a ceramic tile large enough to cover a large portion of the dustcover and add a weight if there remains a bit of bloat to the sound. If an additional weight makes no difference then just don't bother with it.
