The Sony PS-X600 Biotracer undercuts the Ariston RD11 by $75 — $375 against $450.

The Ariston RD11 spins its platter via belt drive; the Sony PS-X600 Biotracer 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.

The Sony PS-X600 Biotracer is fully automatic — press start and the arm cues itself and lifts at the end of the side — where the Ariston RD11 needs you to cue the arm by hand.

Bottom line: the Sony PS-X600 Biotracer has the lower reference price; the table shows which documented features change with the $75 gap.
