I never use the control for selecting tracks, but I just rotated the knob without turning the unit on and noticed subtle but definite detents. As an aside, the 5400ES is very responsive to the Logitech Harmony One universal remote I use, much more so than the DVP-S900ES it replaced. Perhaps it was the download to accommodate the new unit. The sound quality of the 5400ES really is grand. I prefer analog XLR for both CDs and SACDs with the 5400ES, whereas I preferred digital coax to my Proceed PDSD for CDs with the 9000ES.
