Doshi Audio first crossed my radar at the 2010 Rocky Mountain Audio Fest, where I wrote that the sound of the company's tubed monoblocks and preamp, connected to Wilson Audio Sasha loudspeakers via Transparent XL cables, "excelled in midrange strength as the system threw an exciting soundstage." After auditions of Doshi-Wilson pairings at many subsequent shows had convinced me that Doshi's products could truly sing, I contacted company owner and product designer Nishith "Nick" Doshi to inquire about reviewing one of his amps.

The original PS Audio Sprout, which I reviewed in the May 2015 issue, showed newcomers an easier, smaller way to amplify music recordings in the home. At $599, the Sprout100 costs $100 more. It fixes a few of the old Sprout's weirdnesses: no power-on indicator light, no remote control, five-way binding posts that weren't really five-way. It also doubles the Sprout's class-D power output into 4 ohms, from 50 to 100Wpc (or 50Wpc into 8 ohms), and adds a few sonic and mechanical enhancements.

Borrowing a page from the Montreal show—and, before that, from the shows sponsored by Stereophile—Toronto Audiofest presented some live performances of music. One of the performers was the gifted cellist, Vincent Bélanger—see photo above—familiar to audiophiles from his recordings and appearances at audio shows.

Vince Scalzitti's Tri-Cell Enterprises had five rooms on Level 4 of the Westin, with lots of product introductions. One that caught my eye was a piece of equipment that looked like it was from an airplane used in WW II. Labeled a "Puristic Audio Apparatus," this was the Thöress F2A11 integrated amp ($11,500, all prices in Canadian dollars unless marked otherwise) and is cradled like a baby by Vince in the photo above.

I had all but resolved to move on from reviewing recordings honoring the 2018 centenaries of Claude Debussy's death and Leonard Bernstein's birth when word arrived of Warner Classic's 10-CD bargain box, Debussy: Ses Premiers Interprètes / His First Performers. This set's contents are so important that I want to give Debussy lovers a heads-up so that they can either make room for it in their holiday self-gift basket, give friends ample notice for what they'd like to be playing when 2019 rolls around, or start streaming immediately.
