Maximum Impact is one of the biggest UK hardcore labels, with very few (if any) fillers in the catalogue. The sound is characterised by very worked out melodies and decent vocals and 'traditional' hardcore elements such as breakbeats, bold pianos and the usual samples.
There are also small bits that make the records very DJ friendly. The vinyls have excellent (and very loud) mastering and much attention is paid to mixability, such as the intros and outros gained to max - excellent for starting a set. Plus, I don't know if this was intentional or not but the labels look damn cool under blacklight.
