I do like this player. Good price, clever design, and a really nice sound. But I have three, minor suggestions.
First, on the black/gold version, you should color the buttons with lighter paint, e.g. gold to match the cover or even white. It's really hard to make out the function of each button when it's a black symbol against a black background. You have to actually pick up the unit and peer closely to see which button you're pressing, although I'm sure I will eventually memorize which is which. Right now, I guess by touch and counting from right to left! Lol.
Second, I would keep the digital readout on the same side of the circle as the buttons, and move the power switch and power light to the opposite. Right now, you have to choose between seeing the buttons or the readout.
Third, I have noticed that the device is too picky about older CDs. I tried to play a couple from the late 80s. They are in good condition: clean and no scratches. But the Trettitre grinded and rattled for a bit ... and then rejected them. Not the end of the world; I have plenty of newer ones. And older, remade CDs don't sound as good as vinyl or even modern streaming anyway. (At least I don't think so.) And that wouldn't be the Trettitre's fault. Still, it would be nice to play my whole collection, not just a large percentage of it.
All that said, I don't regret the purchase. Well done!
