A simple test is to drape a towel over the table top. If there is no difference, don't worry about it. If it's an improvement, keep the towel nearby for "serious" listening sessions or experiment with removing the table.
Back when I needed to have the table in the room due to WAF considerations - I could hear it, but the effect was relatively minor. Draping a towel over it to remove first reflections worked well enough - at least for me.
I guess it’s this “minor” stuff I am having an issue with.
First no designer of a speaker is designing them with a reflection directly in the dispersion pattern of their transducer; Gobel, Wilson and Magico surely aren’t if you look at how they design and their methodologies of testing results.
Ignoring the above my point reverts to the “minor” issue effects when this forum is filled with threads to correct such “minor” effects (many claim major) often running into thousands if not 100s of thousands of dollars.
Call it the Audiophile Paradox where we spend tons of money to correct the minor/major effects with stuff just to ignore it all because “it doesn’t make that much of a difference”. Sorry I find it laughable but that’s me. I’m a cynic.
