Manual block is right on. It's not the sound that is dectectable inside the cover thats at isssue, its resonance and vibration. Sound in the room can also excite vibrations by stiking the cover which could then be picked by the cartridge/stylus. I would think your extra heavy cover would cut down on this, but it may depend on the resonant frequency of your cover. Everything, even large massive things like the planet, have a resonant frequency. You would still have the echo chamber effect spoken of by manualblock. I find mine sounds best (to me) with the cover up. But I would like a big "cake cover" like that, even with may regular cover on to eliminate dust getting on it. I usually keep a clean T-shirt thrown over it!
