Practical differences
Highlighted cells show a lower reference price, support for more listed speeds, or the presence of a convenience feature. They are not an overall score.
On price alone the Pro-Ject X1 B costs less, coming in $100 (about 7%) below the Mobile Fidelity UltraDeck.
Both are belt-drive, so that part of the experience should feel similar on either deck: a motor that's mechanically isolated from the platter by an elastic belt, which is the usual route to a quieter noise floor — the default choice across most of hi-fi.
Bottom line: $100 separates these reference prices. That difference is factual; this specification comparison does not assign an overall winner.
