Norway’s Hegel Music Systems makes CD players, DACs, and amplifiers -- integrated, pre-, and power -- and since its founding has focused on solving the problems that plague contemporary amplifiers, such as harmonic distortion. In fact, harmonic distortion so intrigued founder Bent Holter that, in the late 1980s, he wrote his thesis on the subject. Among the technologies to come from this research has been Hegel’s patented SoundEngine circuitry -- now reincarnated as SoundEngine2 -- which seeks to retain the original detail and dynamic range of the signal with error-correction technology. The various blocks of an amplifier -- input, gain, and output -- are usually connected in series, but each block produces distortion before the signal is then sent to the next block, where that distortion is then amplified again, along with the signal, to later be minimized by a global feedback loop.

Organist Dr. Lonnie Smith returned to Blue Note Records in 2016 with Evolution, an entertaining and intelligent slice of soul jazz that was one of my favorite discs of that year. He’s back again on Blue Note, and this time producer Don Was recorded him live with his trio at the Jazz Standard, in New York. The show was a celebration of Smith’s 75th birthday, and this seven-song set illustrates the organist’s versatility and the timelessness -- the freshness, even -- of the kind of music he’s been playing for so long.
