Thump when new transport tray closes

I have a Perfectwave Transport on audition and have noticed that there is an audible “thump” when the tray closes. I have never heard this noise on any previous disc players. Is it normal with this unit?

Mine thumped when I owned it.

Yes, this is normal behavior. I have a few folks write to me when they first got their transport. Nothing to worry about at all.

Thanks for clarifying.

I wonder if Marantz SA10 has same “thump” since PST uses same drive. Maybe, SA10 owner can shade some light.
