On iconic singer-songwriter James Taylor's 20th album, American Standard, the lanky crooner adapts the classic American songbook to his easy-rolling musical ways. The result is an American mixture of timeless songcraft.

Where some popular singers use the songbook canon to increase record and ticket sales, Taylor has no need to change himself or increase his audience. He's as comfortable as any man can be, having sold many millions of records the world over for almost 50 years.

Lately, current amplification–based moving-coil phono preamplifiers have gotten a great deal of well-deserved press. For years, Haniwa's Dr. Kubo has been designing and selling super–low-internal-impedance cartridges because such cartridges work best with such devices. He has also been designing and selling his own current-amplification phono preamplifier.

I want to talk about the acoustics of live music and recordings. As I write this I'm back in Boston for a week, re-calibrating my ears with (excuse the expression) the "absolute sound" of live music in various concert halls. On Friday the Boston Symphony played symphonies by Mozart and Shostakovich, producing (as always) magnificent sound with the aid of Symphony Hall's near-legendary acoustics.

I felt like I'd just been offered a choice of 31 flavors of Baskin-Robbins ice cream topped with up to 57 varieties of Heinz ketchup, 57 condiments, and 47 brands of coddled cream. My head began to spin, my stomach churned, and my mouth grew very dry as I read that Gold Note's DS-10 ($2995) was a "chameleon DAC" with 192 setup options that enable it to "completely blend in with different music genres, giving the listener the opportunity to adapt the behavior of the unit to the music playing, to one's stereo system and, most of all, to the listener's taste."
