My biases...

March Audio - Progressive, resolute, getting ahead
Magnepan - Good non-stick coating, will last forever
Revel - For the enjoyment of revealing equipment
Hypex - Overhyped amp boards for the nerdy DIYer, comes with LCD lighting for the gamer
Purifi - Cleans your audio sources of all impurities for the cleanest sound
Sound United - SuperPAC with dark money behind glitzy marketing brands

Parasound - Winner of para-audio competition for customers with special needs
