The last two years I started to notice that I have a lot of new records that produce a lot of noise near the center, especially on the left channel during loud parts. At first, I thought that my equipment wasn't set up properly or something wrong with it. Checked with multiple MM cartridges (mostly Ortofon, but also Grado and AT) and an MC (Benz Micro Glider SL). All produce the same issues, even after checking the settings. Things I've checked and tried out are: - VTF using a digital scale - VTA using an acrylic adjustment block and torpedo level on tonearm - Anti-skating using a blank record and dedicated test record - Azimuth using an acrylic adjustment block and a mirror - Aligned cartridges both using a Stevenson protractor and the Technics overhang gauge that came with my turntable - Leveled turntable using two different bubble levels and torpedo level - Set the load capacitance/resistance according to specs - Even checked the tonearm resonance to be within the specified range of 8 to 12Hz - Last but not least, I tried various cleaning methods for both the styli and the record So I suppose that the settings can't be the issue or am I missing something? I have the same distortion on some older records, but it seems to be common with these newer records... Because of that, my question is: how common is it for new records to have IGD issues and do other people have similar experiences?
