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 Mobile Fidelity UltraDeck costs less, coming in £50 (about 2%) below the Pro-Ject X8.

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: £50 separates these reference prices. That difference is factual; this specification comparison does not assign an overall winner.
