Just to add to an earlier post:
The record spins at a constant angular velocity (33 and a third RPM for LPs). The linear velocity of the record at a particular point with respect to the stylus is equal to the effective radius of that point (i.e. the distance from the record center to that point) multiplied by the angular velocity of the record.
The linear velocity changes constantly as the stylus spirals inward. It is largest at the outside of the record and drops toward the center.
The higher the linear velocity, the better the sound. Thus the inner part of the record will always sound worse thsn the outer part. Many audiophile recordings intentionally avoid using the inner third of the record to achieve better audio quality.
Are you noticing an overall drop in quality, or something more severe such as mistracking? If the former, then welcome to the world of vinyl. If the latter then recheck tour setup.
