The Greek symbol Phi φ has many contexts in science. Once we finalized all the incremental improvements made to the original AB-1266 speaker driver, it seemed a fitting suffix to this iconic Abyss model. This latest Ceramic Coated 'CC' version sports a high-tech, durable two-tone polymer ceramic coating on the all metal frame along with newly designed ear pads for greater comfort and improved sound quality.

Musical information is clearly defined, harmony can easily be heard as individual singers within the group, instrument separation is crazy good, bass drums have the rolling of their skins, ‘bass within bass' as we call it. In essence it transports you back to that time and place.

The AB-1266 Phi (AB-1266φ) refines the sonic virtues of our finest headphone with excellent transparency to the source, and hard hitting low frequency impact and resolution. The sound of these headphones easily compares to and in many areas exceed the finest two channel audiophile systems money can buy. More importantly, the AB-1266 Phi will preserve in history one of the finest headphones ever produced.
