The market for Meridian kit blows hot and cold and just comes down to demand at a given time. The 218’s have all gone up in price. I managed to get mine for £500 which was a ridiculously good price and a set of 3100’s for £400 plus 33’s for £150 a pair.

More recently I’ve seen the above fetch hundreds more.
