darTZeel writes: “darTZeel NHB-458 is the result of nine years of research and development. Introduced in world premiere at the T.H.E in Las Vegas in 2010, it has not ceased to win awards and to be praised in specialized magazines. In 2017, the NHB-468, with its further improved circuitry, became darTZeel’s flagship instrument in terms of power amplification. Reworked in 2020, then sublimated in 2022.”
