If Stereophile gave an award for Loudspeaker We've Most Frequently Reviewed, the hands-down winner would have to be the Quad ESL. The list of past and present Stereophile contributors who've written about the ESL's various incarnations includes John Atkinson, Martin Colloms, Anthony H. Cordesman, Art Dudley, Larry Greenhill, J. Gordon Holt, Ken Kessler, Dick Olsher, Herb Reichert, William Sommerwerck, Steven Stone, and Sam Tellig. The ESL-63 was John Atkinson's personal "Editor's Choice" in 1992, and the ESL-989, a successor to the ESL-63, was Stereophile's 2003 Loudspeaker of the Year and Product of the Year.

Defining noise is tricky business.

In high-end audio, noise is often defined as the enemy—of music, beauty, truth. Engineers and enthusiasts alike spend significant amounts of time, energy, and money attempting to minimize or control noise so that it has the least possible impact on the source signal: music. In this way—if we are intelligent, careful, and fortunate—we can extract from our stereos cleaner, clearer, more naturally beautiful sound for listening experiences that are enriching, emotionally compelling, and, above all, fun. On the other hand, when noise is allowed to excessively modulate the signal, music can sound relatively abrasive, more mechanical, and, ultimately, less engaging.

In this video I profile New York-based tube electronics technician Blackie Pagano, who fixes and upgrades "anything that makes or passes music and utilizes vacuum tubes." I first learned of Blackie when looking for a repairman to take my Fisher 800-C to. JA, Herb, and everyone I asked said—without hesitation—"You have to take it to Blackie. He's the best for the job."

With Quad's reworking of Peter Walker's "Wonder," the full-range ESL-2912 electrostatic, featured on its cover. Inside you'll find John Atkinson on Rockport's Avior II loudspeaker; Herb Reichert on an affordable amplifier from Emotiva and cost-no-object headphones from Abyss; Art Dudley on a Bryston's CD player; Michael Fremer on Brinkmann's MQA-capable Nyquist DAC and Ortofon's Windfeld Ti cartridge; and Jim Austin on PS Audio's ultimate monoblock.

Conductor Osmo Vänskä, whose Minnesota Orchestra has previously distinguished itself in multiple recordings of Sibelius and Beethoven, is now turning to the symphonies of Gustav Mahler. Newly arrived is his hybrid SACD, for BIS, of Mahler's Symphony 5. The first issue in a projected series that will next offer Mahler's Sixth and Second Symphonies at dates unspecified, it may not win over those whose allegiance adamantly rests with Bernstein, Chailly, Rattle, Abbado, Tilson-Thomas, Fischer, and/or other distinguished Mahler interpreters. Nonetheless, the strength of the recording's first movement alone, and its hi-rez provenance as DSD derived from 24/96 file, make its epic journey from darkness to light essential listening.

If you can put aside the fact that what was once a rock 'n' roll band has now grown into a merciless money machine, and a somewhat creaky repetitive live act that hasn't made a great record since 1978, they still do deserve a nod for never saying die. To borrow a famous line from Midnight Cowboy, those boys are gonna die on the stage. And yes, we will certainly miss them when they're gone!

One day before the Los Angeles Audio Show, Jason Victor Serinus, his fresh haircut, and I visited VTL Amplifiers, Inc. in Chino, California. We were given a tour of the factory by Bea Lam and Luke Manley, who were featured in this 2007 interview by Jason.
