VTA and tracking force are interactive, and this may be affecting what you're hearing. I don't know what the manufacturer's recommended maximum tracking weight is for this cartridge, so I will just assume you're not exceeding that. And, I will assume that backing off the tracking force still allows the cartridge to track well. If the sound "thins out" when you reduce the tracking force, try lowering the VTA slightly.
