Actually leveling with 4 IS much harder than with 3. Three is the most stable...with 4 you must make sure that there is sufficient weight on all 4 "feet" and that none is just hanging. It makes me wonder why manufacturers do 4 feet instead of 3
Turntable leveling...
I have a Rega P9/Lyra Delos and my cabinet is not perfectly level. My bubble level shows about 25% of the buble outside of the circle and digital reading shows about a -1.4° as the most declination on the TT. How important is it that I get it spot on? I would need to complete unload the cabinet to level it at it feet. It is a heavy cabinet with a marble top. The wt of the equipment in it probably exceeds 250 lbs.
