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.

The Trio/Kenwood KD-550 undercuts the Thorens TD 320 by $50 — $500 against $550.

The Thorens TD 320 spins its platter via belt drive; the Trio/Kenwood KD-550 uses direct drive instead. Neither is objectively better — 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 versus instant start-up, rock-steady speed under load, and enough torque to nudge or backspin the record — the reason DJs and scratch decks are built this way.

Bottom line: the Trio/Kenwood KD-550 has the lower reference price; the table shows which documented features change with the $50 gap.
