Uniformity in the recording process since the advent of the stereo LP and later on by the use of compression varies greatly. Without knowing your taste in music and the amount of reissued vinyl in your library your roughly "60%" of dissatisfaction is understandable to me.
At the California Audio Show I listened briefly to your brand of speakers (can't say which model) and cartridge. I can't quite remember the brand of component electronics, Pass Labs? I do recall they used a subwoofer.
A subwoofer with modern equalization audition would be my first suggestion. The second would be the cartridge. The cartridge IS the transducer, the heart of LP playback. Unfortunately auditioning a cartridge is almost impossible. If your dissatisfaction continues after an improved sounding cartridge...well that's one less thing. IMO, aside from the minor azimuth issues with the concave platter its difficult to out class the Well Tempered turntable with a high end cartridge.
