Should the tonearm be horizontal to the record? The reason why I ask is because some members on the forum did not experience any sibilance whilst using the 2M red cartridge but I did, and I have been told that I should not have had any sibilance in the first place if the VTA was correct. I do have it horizontal (used the human eye)to the record when lowered so is it wrong? or is there a sure fire way of getting it 100%? I have the 2m blue so want to make sure I am getting it right
