"There are 24 bipolar output devices per channel, bolted directly to the heatsink on the side of unit. The power supply has a very large capacitor bank—there are large, US-made electrolytics in the main cap bank—as well as lots of smaller, German-made, high-frequency WIMA film caps throughout the unit."
The M15 accurately delivered the extraordinarily wide soundstage and warm midrange captured by engineer John Atkinson in his recording of the Portland State Chamber Choir in performances of Eriks Ešenvalds's Northern Lights, from Into Unknown Worlds (24/88.2 FLAC and 24/44.1 MQA.FLAC, CD Baby). However, the M15 curiously favored the voices of the men over the higher voices of the women, to the detriment of director Ethan Sperry's carefully balanced choral sound, and the radiant shimmer of glockenspiel and glass harmonica that make the conclusion of this work so mesmerizing lost some of its glisten. Through the dCS Rossini, the MQA version of this track sounded more transparent, as if a veil had been lifted, but the tonality was still a bit gray, and the "sparkle" that the choir sings of, and that Ešenvalds depicts in sound, had lost its, well, spark.
There were some positives to this sort of sound. "Electrified II," from Yello's Toy (24/48 WAV, Polydor 4782160/HDtracks), is a hot recording with electronic sizzle deliberately added to voices. Not only was that annoying component of this otherwise stellar recording toned down to the point that I could raise the volume without pain, the undertones of voice and accompaniment were also well fleshed out. The music may not have been as electrifying as usual, but the ability to play it louder than before made for an exciting few minutes.
