This trademarked amplification schematic opens new technical perspective, but more important, gives striking and surprising results. The tubes not only provide their well know smoothness, but also an extreme precision in micro details. The voices (acapella) are expressed with unreached natural, without any halo or reverb effects.  The instruments are perfectly focused (and can be spatially tracked) with an unusual stability. The dynamic reveals the most subtle percussions, with unexpected and unmatched energy! Not “tube” nor transistor, come try the Kora sound!
