The main purpose of the Diabolo is to satisfy some Hi-fi friends who have preferences on ROCK music.
The Diabolo got excellent performance when listening fast-tempo songs, and its high-range is direct and clear, intermediate frequency is concise and low-frequency is full of cohesion and forces. Once you taste of the detailed sound and the equilibrium point, you would find that high-frequency is relative calm, not so outstanding amount of sense and hardness which could ensure that there is no fatigue on the sense of hearing. Low-frequency part of the sound is quite prominent. Firstly the low and intermediate frequency interface is very full, so that the intermediate frequency has been well supported. Thus, strengthening in the low range would not seem awkward and lack of coherence. Meanwhile, the low frequency section of the volume being raised, the human voice is also benefited.
I would love to buy the Diablo cable if the above written stuff is true . But I wonder how someone can tune so much and be so specific about frequencies just while making a cable :S Do they make the cable keeping the desired sound / description in mind or write the whole description after some random cable is made and tested :rofl:.
