"As the original L2 circuitry was virtually flawless, it was the emergence of new electronic components that opened up a possibility of [even better performance] . . ."

So begins one of two booklets—one a collection of specifications and interior photos, the other a distinctly thorough user's manual—included with the new L2.1 Reference line-level preamplifier from Brooklyn's Lamm Industries, earlier products from which have impressed me as among the best available. Indeed, coming from almost anyone else, the above quote would strike me as trivial boasting—but I know from experience that there's nothing trivial about designer and company head Vladimir Lamm.

For digital playback, in recent months I've been breathing some rarefied air, pricewise. In December 2016, I reviewed dCS's Rossini Player and Clock, followed in May 2017 by Meridian's Ultra DAC, and in June by Chord's DAVE DAC. The Rossini Player costs $28,499 without the Clock, the Meridian $23,000, and though the DAVE is less expensive than either at $10,588, that's still a fair chunk of change. Even PS Audio's PerfectWave DirectStream DAC, which I bought following Art Dudley's review in September 2014, costs $6899 with the Network Bridge II, which hardly counts as "affordable."

Thursday evening, June 22, 5–9pm, F1 Audio (311 E Dundee Road, Palatine, IL 60074) is holding an event featuring Evolution series loudspeakers and electronics from TAD Labs and Isotek power conditioners.

At the Los Angeles Audio Show, held June 2–4, John Atkinson spoke with Elac's Andrew Jones about speaker design, building affordable loudspeakers, and Elac's Adante AF-61 speaker, which made its debut at the show, driven by Audio Alchemy amplification.

Want to go from yang to ying by the simple switch of a silver disc? Try seguing from the two supremely energetic, densely populated chamber symphonies of Pulitzer Prize-winning composer John Adams (b. 1947), which we explored last week, to the far milder and less complicated choral work, Canticles of the Holy Wind (Cantaloupe) from the other Pulitzer Prize in Music-winning Adams, John Luther Adams (b. 1953).
