The impact of turntable mats on sound quality has been a topic of controversy for a long time. Common felt mats allow for a gentle contact between the record and the platter, but they have issues with static electricity buildup. This can lead to significant dust accumulation on the mat and record. Additionally, their damping effect is limited, which can be particularly problematic with metal platters. Thick rubber mats often dampen too much and also prevent the dissipation of static charges from the record, resulting in noticeably more crackling and popping sounds. Leather and cork are two completely different but very interesting alternatives. Both dampen resonances better than felt, do not attract additional dust, and can dissipate static charges. What is better for your turntable depends on personal preferences as well as the material of the platter. It is a very cost-effective method to improve sound quality and reduce unwanted noise from dust and static electricity. You will hear the difference. Material: leather. Diameter: 300 mm.
