To me, the class-A/B Moon 371 integrated amplifier is one of the most significant products of this past year, largely because it fulfills what we, as audiophiles, hope for in a full-featured, all-in-one (including streaming) product: a combination of new technology and functional convenience married to the kind of superlative sound we'd expect from separates.

The two units' back panels are not simple. To attempt to detail every connector would induce a soporific state in most readers and certainly this writer, so we'll just publish a photo and focus on the basics. On the back panel are two sets of speaker cable binding posts to facilitate biwiring, single sets of RCA, BNC, and XLR inputs, balanced XLR analog outputs for amplifier chain connection, an earth-ground socket, a ground-lift switch (footnote 2), and a signal-ground socket. And more.

The power supply's rear panel is simpler and less crowded. It includes a main power switch,…

"And how long have you felt this way about audio components?" my therapist asked. His pen scratched on his notepad.

"Gosh, it seems like forever. My mother told me I would nurse only if she sat down with me next to Dad's old Garrard record changer while it churned through a stack of LPs."

"Hmmmm." He paused, then resumed writing.

"Hey, Doc? Is there anything to drink around here?"

Sometimes I think audiophiles are crazy. If the point of it all is our love of music, we often forget that the brain is where it happens—not…

If you dare stack the two units one atop the other (I had no choice in my modest-sized music room), each stack proclaims might and—given the front panel's minimalist Swiss styling—refinement.

On the levels of sound and music…

In common with CH Precision's M1.1 amplifier, the M10 includes the facility to adjust feedback on the fly via the company's intuitive app. In the M1.1, feedback could be adjusted to the nearest 10%; in the M10, the adjustment has 1% increments. Of course, the "0% feedback" setting does not really mean "zero compensation" as there's always sufficient local feedback to manage the bandwidth, gain and stability of the M10's input and output stages.

Just like last year, I saved retailer Audiophile Experts' room for last. I stopped by their room at the 5pm closing hour on Sunday, as the crowd headed home and exhibitors started dismantling their setups. That's because Stacy and Mathieu, proprietors of Audiophile Experts, like to cap off my harried show reporting with a soulful, uninterrupted musical performance, usually from an analog-fronted rig.

This year's source was a B77 MkIII reel-to-reel machine by Revox, for which Audiophile Experts is the exclusive Canadian dealer. The system also included an Accuphase C-3900S…

When the Wigmore Hall Live label was launched in 2005, the great mezzo-soprano Lorraine Hunt Lieberson had only a few months to live: She died of breast cancer in July 2006, age 52. The hunt for lost recordings to memorialize her artistry led directly to her November 30, 1998, Wigmore Hall recital, broadcast that day as part of BBC Radio 3's Noonday Concert series and preserved in the BBC archives. That recital was released on the Wigmore Hall Live label on January 1, 2007, six months after Hunt Lieberson's passing.

How is it that an archival broadcast recording became a widely…
