CD transport tray mechanisms are relatively complex and can become finicky and unreliable over time. I love and appreciate the straightforward simplicity of the top loading RS2T. To boot, its spinning mechanism unit is astutely thought out and isolation/vibration management is very well addressed.
My P.S. Audio PWT served me quite well sonically for 12 years. Occasionally the sliding tray would get stuck and not open. This is not a concern obviously with the RS2T top loader.
