Long experience has convinced me that many audiophiles' stereo systems substantially underperform compared to what they could sound like. This is not because people haven't spent enough money on their electronics or speakers. Instead, people aren't getting all the performance they've paid for because they haven't devoted enough attention to all aspects of the initial setup, and/or to maintenance and updating.

In collaboration with Coursera, the online learning company, and starting September 3, The Curtis Institute will be offering at no charge the course Exploring Beethoven's Piano Sonatas, taught by Curtis Institute's Neubauer Family Foundation Chair in Piano Studies Jonathan Biss. The course will last five weeks, with an anticipated workload of 1–2 hours a week.

First, two noteworthy CDs. San Francisco's Cypress String Quartet, whose set of Beethoven's late quartets and high-resolution downloads I praised in the April issue, is back with a new CD (Avie AV2275) that explores their musical roots.

Talk about a fascinating personal history. Rising-star jazz pianist Aaron Diehl's father ran a funeral home in Columbus, Ohio, with a largely African-American clientele. Diehl started at the piano with Bach, and not long after was playing in both the funeral home and a nearby Catholic church. I think the significance of those early experiences is not so much that a young teenager was already playing for audiences, but rather that he was playing in the context of rituals and, in the case of the funeral home, emotionally fraught major life transitions. I suspect that Diehl's unusual backstory is a large contributing factor in his musical maturity and poised artistic approach.

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.

Since its founding, Boston's famed Berklee College of Music has marched to the beat of its own drum section, preferring experienced working musicians over credentialed academics as instructors, and emphasizing practical knowledge over disembodied theory. In collaboration with Coursera, the online learning company, and starting March 1, Berklee will be offering at no charge the course Introduction to Music Production, taught by Berklee instructor Loudon Stearns.

The Anima is a two-way loudspeaker from Canalis Audio, a new enterprise of longtime importer Immedia, of Berkeley, California. Canalis is thereby related to Spiral Groove, and Canalis speakers bear the Spiral Groove logo on their terminal plates. Spiral Groove, founded in 2005, makes turntables; their SG2 ($15,000) was favorably reviewed by Brian Damkroger in the June 2010 issue. Canalis makes at present four models of loudspeakers, all designed in collaboration with noted engineer Joachim Gerhard, formerly of Germany's Audio Physic. All Spiral Groove and Canalis products are made in the US.
