If I am able to give a like to akg_ca’s post, I’d do it.
Just to add, the old Monitor 30 is a far cry from the 30.1, 30.2 Anniversary and the latest 30.2 XD. If buying used, avoid the M30 at all cost as the sound is excessively shut-in, warm and thick with a severe lack in clarity and detail. Treble is rolled off and devoid of sparkle and extension.
With SHL5, the SHL5+, Anniversary or XD models are the ones to look out for. The older SHL5 does not sound as balanced as the later models.
