I have to go up the cudgels for the Head Box II here. As used herein and should be read in other forums of KHV cuts so bad in the underground audi hydrophilic fraction from. I say from me a pretty good ear for music and sound characteristics bring, because I have since childhood been dealing with HIFI and through the living room of my parents and now also my living room very many HiFi equipment from leading manufacturers (Audi analysis, Tannoy, Kef, B & W, Audio Research, Linn, Burmester, Symphonic Line, Dynaudio etc.) have migrated. Thus, I have been allowed to enjoy many hours of music and sound characteristics of different products. Basically, everything is only once a matter of taste. Some like the clean, clear sound and possibly analytic the other more to warm any bassy sound. I run with the Head Boxx II a AKG 701 and feed the Head box with my LAPTOP !!! Oh now say most, but I have a Realtek High Definition Audio sound card and driving them 24bit / 96kHz Resolution. I can not complain about the sound characteristics in this combination. A clean very highly detailed musical sound with decent attack and good bass. I can only put all my heart not of effusive and unjust recessions or to be swayed to the bad reputation of the Head box. You have to hear the combination of each device always. And ultimately decides yes still the personal listening preferences and the personal taste.
Conclusion:
Pro: + Well-constructed KHV + Very good sound quality + Very good haptics + Beautiful appearance
Cons: - Power supply could be valent - Heard a very faint humming at full scale and touching the case
All in all a very good KHV with which one really can not go wrong.
