I will have to disagree with your statement. I bought the Diana Phis as i was wanting a lighter and more comfortable version of the 1266 Phi CC, and the Diana Phi delivers this in spades! After owning several LCDs from Audeze (including the LCD-4), and then most recently the 1266 Phi CC i wanted to get a headphone that i could wear all day if possible. I really enjoy the bass that planars provide and i was very impressed with Abyss' offering and that's why i went for the Diana Phi when i heard it was 90% of the 1266 Phi CC. I would personally say the Diana Phi gets 95% of the way there. However, i will say that the Diana Phi needs a powerful amp to drive it well and that is the only thing that doesn't make it a true portable headphone.
