I have a Lyra Delos chewing-gummed (just kidding!) to an Alphason arm attached to an older but several-times-updated SOTA Sapphire turntable. I have the Delos as level as possible, tracking at the recommended 1.75 grams. Unfortunately, I had to set the level by eye, as the shape of the Alphason makes it impossible to put a spirit level atop the thing. I cannot remember the LP I used to level the tonearm, but it was probably from London/Decca or DGG, and not a super-thick audiophile pressing. In any case, no matter what brand of LP I play, tracking, tracing, edge-warp handling, inner groove distortion and every other phono nasty is virtually non-existent with the Delos. It's as unflappable a cartridge as was my dampered Shure V-15 Micro Ridge.
