This review features the KST-100 stereo power amplifier. Initially this product was differentiated from the more expensive Krell components by having an all-black livery. However, as customers showed a preference for Krell's traditional anthracite finish, the KS series is now also available in this finish.

Oh boy. The folks at Massdrop have gone and done it again. Just got their new Massdrop x HiFiMAN HE4XX in for measurements and a quick listen before the drop.

This is a gorgeous recording. And would you believe, it's multi-miked? Sheffield's first since 1975, according to the notes. Ms. McBroom has that purity of intonation that once distinguished Julie Andrews' voice. This, plus a predominantly-string backup orchestra delivers a rich, warm sound. Each of the songs here is a gem in its own right, and the collaboration of McBroom and Mayorga creates moments here that are magical. My favorite is the song entitled "Amanda," with its frontier flavor and unadorned lyrics, followed by Mayorga's'waltz, "Wistful Lady."

It's customary to think of "the tube sound" as being warm, rich, weak through the deep bass, fat through the midbass, forward through the midrange, bright through the middle highs, and soft at the extreme top, with superb rendition of depth and spaciousness. The "solid-state sound," by contrast, is generally thought to be cool, detailed, and pristine, with powerful deep bass, controlled midbass, rather reticent (laid-back) midrange and mid-highs, and a somewhat crisp high end, with variable (roulette-style) reproduction of depth and spatiality.

His new two-CD album, Meditation / Resurrection (on the AUM Fidelity label), was recorded in the course of a single day last October, at Brooklyn's System Two Studio by Michael Marciano, who also mixed it live, to give it the feel of a spontaneous set at a club.
