CES 2017 saw the introduction of the 350Wpc Mark Levinson No.534 stereo amplifier ($20,000). Todd Eichenbaum, Director of Engineering for Harman International's Luxury Audio Group and designer of the No.534, explained that it was developed to fit between Levinson's entry-level No.532H stereo amplifier ($8000) and the $50,000/pair No.53 reference monoblock amplifiers.
Classé premiered its new Delta 3 amplifier series at CES 2017. Rated at 350Wpc RMS, the Delta 3 Stereo ($10,000) employs lateral MOSFETs in its output stage and 234,000 microfarads of German-made 4-pole Mundorf electrolytic capacitors in its power supply.
Jewelers Philippe and Mathieu Tournaire add 18-karat bands of gold at each end of the Utopia's headband, and each is set with three 1-karat diamonds in square, triangular, and round shapes, representing the three stages of life: the past, the present, and the future.
In the YG Acoustics-Audionet suite, the sound on playback of Jake Shimabukuro's ukulele wizardry came closer to matching his live performance than in most rooms, perhaps as a result of the excellent match between the Audionet Max monoblock amplifiers and YG Acoustics Sonja XV loudspeakers.
In the D'Agostino exhibit, pure AC power was fed to the Progressive monoblocks by a Stromtank independent power source ($30,000): a 276-lb enclosure in which a 16-cell Lithium phosphate battery pack stores up to 4000W, ultimately to be converted to pure-sinewave AC.
