Balance is certainly a lovely concept, as well as a lofty ideal. But achieving an optimal sonic balance in a high-end audio system—whose final sound is determined, in part, by interactions among any number of components and that great bugaboo, the listening room—while maintaining some semblance of psychic equilibrium can be the hardest goal of all.

In anticipation of this week's Munich High End, which takes place May 18–21, MQA has announced several breakthroughs.

All of the latter are expected to demonstrate MQA at the Munich show, with yet others showing at the Los Angeles Audio Show June 2–4.

David Chesky's The Spanish Poems packs a lot of infectious, dance-like energy into a three-song, 24/48 (or 16/44.1) download. Available at a price commensurate with its 21:28 length, the short cycle sets "The Girl from Guatemala" by José Marti (1853–1895), Sonnet No.5 by Garcilaso De la Vega (1501–1536), and "The Romance of Love" by an unknown author. All dance away in a catchy style that makes ample use of bells, triangle, and other high-pitched percussion instruments.

The fabled Nelson Pass, whose 160 lb XA 200.8 class-A monoblocks are an essential part of my reference system, has just gone small with the first appearance of the Pass Labs XA25 class-A stereo amplifier ($4900). With a single pair of 700W devices per side, the single-ended amp delivers 25Wpc into 8 ohms and 50Wpc into 4 ohms, and is stable down to 0.5 ohm.
