That can be a very difficult question to answer because it is hard to compare apples to apples. If I had to make a choice as they stand I would say the VPI is better. The VPI seems to run quieter and seems to have a better all around tonal quality than the 2000X. The depth of soundstage and detail is phenominal. Better than the 2000x. But that may be due to the setup and cartridge combination rather than the turntable itself. The VPI uses the massive periphery ring which will make nearly any warped vinyl perfectly flat making the tonearm motionless and tracking flawless. I am using a Lyra Titan i as its cartridge. I can not mount the Lyra on the standard 2000x YSA-1 or YSA-2 arm so I placed a YSA-39 arm on one 2000x to try to make comparisons. For some reason I am getting feedback hum when using that arm combination; so a direct comparison isn't possible until I can get that problem resolved. The VPI also uses the rimdrive system which isolates the motor from the plinth/platter which I believe accounts for its ability to run nearly silently. The 2000x with the Victor MC-L1000 cartridge sounds very good but with less detail and less dynamic bass. I believe that is more due to the cartridge than the turntable, but the Victor is the best I have that will fit the YSA-2 arm. There does seem to be slightly more background noise with slight rumble in the 2000x which I will assume to be the table at this point. Another comparison which affects sound quality is setup. The VPI can be difficult to setup and dial in. The 2000x is a breeze in comparison. On the VPI when tracking force is adjusted, azimuth will change and vice versa. It is difficult to get both dead on simultaneously on the unipivot arm. Overhang is fairly straight forward. On the 2000x overhang and azimuth are interconnected but are much less finicky to deal with than the azimuth tracking force interconnection on the VPI. I am not sure my explanation is clear but to make a final comparison, overall I would say the VPI has better sound quality but the 2000x is certainly no slouch.
