Solid State Power Amp Reviews

For as long as I've known about high-end audio, I've put Dan D'Agostino, co-founder of Krell, on the same pedestal reserved for the likes of Frank McIntosh, Saul Marantz, Avery Fisher, H.H. Scott, and Sidney Harman. The reason is simple: Dan's the man whose achievements at Krell led me from the harsh sound of my first high-end amp into another dimension, one of truly musical sound reproduction.

Three years ago, when I first heard Audionet's Max monoblock power amplifiers, I described their pairing with YG Acoustics Hailey loudspeakers "an absolute winner" and "definitely one of the finer systems at T.H.E. Show Newport Beach." At subsequent audio shows, no fewer than four other Stereophile Contributing Editors enthused about different pairings of YG loudspeakers with Audionet amplification. Herb Reichert, at the 2014 Rocky Mountain Audio Fest: "Everything had a kind of just right quality. Totally impressive!" Sasha Matson, at RMAF 2015: "Marvelous" on vocals, "rockin' and tight" on bass and drums. John Atkinson, at T.H.E. Show 2016: "Duke Ellington's classic Jazz Party in Stereo . . . was reproduced with terrific dynamics." Larry Greenhill at the 2017 Consumer Electronics Show on the sound in the YG Acoustics room, which included Audionet's Max monoblocks: "the sound on playback of Jake Shimabukuro's ukulele wizardry came closer to matching his live performance than in most rooms."

Has it really been more than seven years since I reviewed Bel Canto's REF1000M monoblock? According to the Bel Canto website, that model, based on Bang & Olufsen's ICEpower class-D modules, is no longer available. But now, like so many manufacturers, Bel Canto has adopted for its new models the NCore class-D module from Hypex—although the REF600M monoblock ($4990/pair) is not Bel Canto's first product to use it . . .
