Popular Amplifier Technologies
Class A - inefficient but OH SO GREAT sound quality. Considered by many as the best.
Class A/B - A more efficient version of Class A but suffers from crossover distortion. It's a mature technology and the best brands manage this Achilles heel well.
Class D - Best possible efficiency. Sound quality has improved tremendously in recent years.
Can make or break a system. There are only 2 conducting materials to consider, including the plugs. Copper is a better conducter than gold, rhodium, platinum, etc and Silver is better than copper (leave gold, rhodium, platinum, for fine jewellery). Other qualities to consider are the conducting material, the Dielectric. This is the jacket surrounding the cable which prevents short-circuiting. This greatly affects sound quality and air is the best material, but impossible to implement 100%. Specialist cable companies go to great lengths to improve dielectric materials.
