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.
