How small can a CD player be? If it's a portable with a flip lid and just one mini-jack output, the answer is little more than ten millimetres thick and a fraction bigger than the diameter of a CD. But we don't reckon front-loading players will ever come much smaller than this Pro-Ject Projectbox, which has a top surface just 50 per cent bigger than one CD jewel case and height (including feet) equivalent to four of them.
