Arthur1954,
I have had zero issues with the slot loader on the Audiolab. I like it much better than any tray loader I've owned, takes discs smoothly, isn't noisy, and reads discs pretty quickly.....all good there
I was initially impressed when I found that the slot loader mech is the exact same one they use in the flagship 8300CD player....but the sound is where the 6000CDT excels.....but use nice cables on the DIG out to your DAC
