    You're not going to get much of a stereo effect from a small box. Quite often these mono sets have stereo output through the phone jack, its worth checking. Finally you will find that some commercial stations are mono anyway.

    You're not going to get any stereo effect from two speakers so close together on a portable unless you press your nose up against it. I wonder why they bother really.

    As mike7 says you're better off using the headphone jack for stereo from these devices.

    the stereo effect on DAB (worse than FM) is very poor, so there's not much benefit in stereo

    Radio 3 uses discrete stereo, where the left and right channels are coded and decoded separately, so the stereo image should be as good as FM. This is only suitable for bit rates of 192k or more, it results in rough-sounding audio if used at lower bitrates.

    The other stations employ joint stereo where the left and right channels are jointly encoded and separated at the receiver end. This is an efficiency device for use at low bit rates and does produce a reduced stereo image compared with discrete stereo.
