It had already been a long week at Stereophile. I trucked through three thirteen-hour workdays plugging in code for the Recommended Components iPad app and had my first dentist appointment in five years. Holes had been burned through my eyes and scraped through my teeth. Luckily, my ears were still there dangling. But the rain, the rain, THE RAIN! I could have done without the rain this morning.

Electronic composer Markus Popp (Oval) may be best known for his terse, angular, and rhythmically complex micro-compositions, but he seems increasingly interested in making full-fledged songs.

With Calidostópia!, recently released as a download, he’s combined the glitchy pointillism of previous releases, such as 2010’s fascinating O (which I used as a test disc in my “Follow-Up” review of Simaudio’s versatile i3.3 integrated amplifier), with the voices of seven South American singers: Agustín Albrieu of Argentina; Andrés Gualdrón of Columbia; Maité Gadea of Uruguay; Hana Kobayashi of Venezuela; and Dandara Modesto, Aiace Felix, and Emilia Suto of Brazil.

The Emotiva “On the Road” tour makes its first stop this Saturday, April 13th, from 9am to 5pm, at the Chicago Marriott in Naperville, Illinois.

As Jason Victor Serinus reported, the New York Audio Show will take place this Friday through Sunday at the Palace Hotel (455 Madison Avenue, at 50th Street) and will host some 250 high-performance audio brands and several interesting seminars.

But the New York Audio Show is not the only audio-related event to take place in Manhattan this weekend. Two major NYC dealers, Lyric Hi-Fi & Video and Stereo Exchange, will hold their own special events, separate from the NYAS. Both events are free to the public and will feature product demonstrations, discounted pricing on demo equipment, and ample time for Q&A with manufacturer representatives.

Reading the November 2012 Stereophile, my eye was caught by John Atkinson's very enthusiastic review (he bought the review sample) of Ayre Acoustics' new QA-9 analog-to-digital converter. Over and above the intrinsic interest of the QA-9's claimed flat response down to about 1Hz, and that it is a cutting-edge ADC from a maker of consumer rather than professional audio gear, I had just been engaged by early-music scholar and organist Beverly Jerold to produce and engineer a recording of historically informed performances of Baroque organ music by Buxtehude (b. 1637), Clérambault (b. 1676), J.S. Bach (b. 1685), and Domenico Scarlatti (b. 1685). The recording venue was the Auditorium of the Third Meeting House of the First Baptist Church in America, in Providence, Rhode Island.
