Anxious to prolong my mono-maniacal buzz, I reached for an early LP version of soprano Bidú Sayão's 1945 recording of Villa-Lobos's Bachianas Brasileiras 5, with the composer conducting an ensemble of eight cellos and one double bass (LP, Columbia Masterworks ML 5231). With the Mr. T, her voice was more human and compelling than without. Again, tempos seemed steadier, and the plucked notes of the cellos had greater apparent force. It was here that the word Wow made the first of many appearances in my notes.

Twenty-five years after the premiere of John Adams' Violin Concerto, the music remains as vital, exhilarating, and strangely moving as the day it was birthed. An extremely demanding work, its three contrasting movements present a triathlon challenge of sorts to anyone who dares try to play them.
Here, she who rises to the challenge is violinist Leila Josefowicz. Provocatively pictured on the CD cover as a curious cross between an athlete in repose and Rodin's reflective thinker, and shown inside the booklet in very hip, thoroughly artistic renegade drag, Josefowicz lives up to her…
On the second morning of a recent audio show, I walked into the exhibit room of Bricasti Design.
"How about some Mahler?" asked cofounder and designer Brian Zolner.
"Oh God. Not at 10am!"
Listening to Mahler had become de rigueur for my visits to the exhibits of this Massachusetts-based company. From the very first time that Zolner had played part of Iván Fischer and the Budapest Festival Orchestra's recording of Mahler's Symphony 2 (SACD/CD, Channel Classics 23506) through a system that combined Bricasti's M28 monoblock power amplifiers, M1 DAC, and M12 Source Controller…
Listening
Having wasted too many hours critically listening to allegedly fully-broken-in gear that was clearly still unready for prime time, I no longer take manufacturer assurances of factory break-in at face value. I cued up a Nordost break-in CD and ran both its break-in and demagnetizing tones through the system continuously at a decent volume for a good three–four days, and began each listening session with an additional 30-minute round of break-in and demagnetization. The M15's sound remained consistent throughout the listening period; it's fair to conclude that it was sufficiently…

Sidebar 3: Measurements
I measured the Bricasti Design M15 using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Before I test an amplifier, I precondition it with both channels driving a 1kHz tone at one-third power into 8 ohms for an hour. At the end of that time, the Bricasti's top panel was warm, at 101°F (38.3°C), and its heatsinks were hotter, at 103.1°F (39.5°C). The M15 has sufficient heatsinking for its power rating.
The voltage gain at 1kHz from the speaker terminals into 8 ohms measured 26.9dB for both balanced and unbalanced signals, and both…
Manufacturer's Comments
Editor: A review in Stereophile is very important to Bricasti Design and to our dealers and export partners, so we took our responsibilities in this matter very seriously. We did our best, in hopes that the process would be transparent and fair, and that Stereophile's reviewer would report on the best that our product the M15 stereo amplifier can sound. We don't think that is what happened, and are very disappointed.
When Jason Victor Serinus approached us at the 2017 Rocky Mountain Audio Fest while we were demonstrating the M15, we told him that in view…
Back at the beginning of 2017, Greg Roberts, of Volti Audio, devised a clever way to bring his Rival floorstanders up to my penthouse pad, for what resulted in a rave review of those horn-loaded wunderspeakers.
I live on the top floor of a seven-story, elevatorless building on a busy street in Greenwich Village. A vertical challenge? No problem! Roberts is resourceful in many things, from speaker design to his former profession, the building of custom homes. Affixing a pair of unguent-saturated straps to the screws on each side of a Rival, we lifted and transported the 106-lb speaker…
