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 Connoisseur BD1 undercuts the Dual CS 505 by $45 — $130 against $175.

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.

Operation differs: the Connoisseur BD1 is manual, the Dual CS 505 is semi-automatic.

Bottom line: $45 separates these reference prices. That difference is factual; this specification comparison does not assign an overall winner.
