Our first sample of this preamplifier was returned to the manufacturer before we had completed our tests on it, and was replaced with the latest version (ours is serial number 500108). Enough time elapsed between the time we shipped back the first sample and the time we got around to auditioning the second that we are unable to report on any sonic differences between the two.

It's not just the gray hairs or the expanding waistline that suggest one is getting old: it's also when the albums you love so much, and so vividly remember hearing for the first time, have become a part of the rock heritage industry.

My current romance with audiophile-quality headphones began in earnest with the appearance, about 10 years ago, of Audeze's LCD-2 planar-magnetic headphones—these predated the company's patented Fazor elements, said to guide the sound around the transducers' magnet structures—and Schiit Audio's original Asgard headphone amplifier. Together, these groundbreaking products rekindled my interest by making headphone listening into something new and exciting—something less distorted, more dynamic, denser, and more intensely lifelike than what I was getting from my speakers on the floor. Best of all, I could listen while lying in bed with my eyes closed.

“Musical scavenger” Bryce Dessner, the composer/musician who gained fame as principal songwriter of American rock band The National, describes his process as collecting sounds that appeal to him and trying them out. Classically trained, he’s one of a growing number of artists whose cross-genre music, when performed by string quartets, orchestras, and ensembles, has been central to broadening the definition of classical music in the 21st century. Dessner is also one of eight “extraordinary artists, thinkers and doers” appointed to a collective that will help steer conductor/composer Esa-Pekka Salonen when he succeeds Michael Tilson Thomas as Music Director of the San Francisco Symphony in September.
