The name ACCUPHASE was adapted by taking the prefix ACCU from the word "accurate", and combining it with PHASE which is a most important factor in audio technology. 

This was the idea behind the slogan "Enrich Life through Technology" which originally brought together the group of very highly skilled audio experts who conceived and today produce the successful Accuphase line of audio equipment. It is the guiding principle behind all Accuphase components whose high grade can be considered extravagant. Just as there are exquisite musical instruments that are especially highly prized, we believe that the same applies to audio components. This belief forms the basis of our design concept. It is the reason why we strive to build extra value into each of our units so that they will display fully the merits of hand construction.
