Two rooms, side-by-side at T.H.E. Show 2021, with two entirely different but equally valid windows on sound. To the left—we are not talking politics here—the UK's ATC loudspeaker company, manufacturer of time-honored active and passive loudspeakers. Courtesy of their reps, Las Vegas-based Lone Mountain Audio, we are hearing the US show debut of SCM100ASLT Active Driver Tower loudspeaker ($41,999/pair, or $50,999/pair in this particular glossy finish; right in photograph below). This is a bigger speaker than the two other speakers that the company usually shows, and the music played via file,…
When Wayne Carter told me that his company, San Diego-based Wayne Carter Audio, designed audio systems for rock stars and also distributed Margules Audio tube products, I knew I had to pair one room with the other. The potential contrast between Carter's "vintage mastering system from 30 years ago"—assembled partly for fun and partly as a tool to help customers understand what was and is possible—and Margules's diminutive gear was too delicious to resist.
"The Lazarus H-1A and Lazarus 200/200s were the electronics of choice back in their time," Carter told me. So (at…
I mentioned this room in the opening blog from T.H.E. Show 2021, but only to point out the unusual nature of its PowerSlave Marble Mk.II power distributor ($18,500), the Stacore Roller Anti-Vibration Platform with cryo-max mass loading+bearing isolation ($4180), and the huge Stage III Poseidon AC power ($22,000) and Cerberus speaker cables ($36,200/pair). While they weren't the most expensive components in the room, their prices certainly topped that of the flagship Aurender W20SE music server/streamer ($22,000).
Despite the prices, Aaudio Imports' multicultural collection went far…
Sticking with my arsenal of past R2D4 picks, and because I knew it would make me smile, I put on Count Basie & His Atomic Band doing "Roll 'Em Pete," from the killer collection Complete Live at the Crescendo 1958 (5 CDs, Phono 870245). Joe Williams nails it to the boards: "Well, you're so beautiful, but you've got to die someday. / All I want's a little loving, just before you pass away." Now that was something to die for—I had to laugh with pleasure. Via the MC462, Basie's piano was charging hard and taking no prisoners. The saxes and brass had such wallop I felt I was being spanked—in…
Sidebar 1: An Interview with Charlie Randall
After being shown through McIntosh Laboratory's factory, in Binghamton, New York, where I saw the integration of cutting-edge and well-established technologies with outstanding quality control, I visited a bit with Charlie Randall, who first arrived at McIntosh as a college-student apprentice in 1985, and 16 years later was appointed President of the company. I first asked him how things are at McIntosh, given the ongoing parade of new formats—portable this, streaming that?
Charlie Randall: Really good. A lot of people thought that…

Sidebar 4: Measurements
I performed a full set of measurements on the McIntosh MC462, using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Before doing any testing, I preconditioned the MC462 by running its 8 ohm output at one-third power for 30 minutes into 8 ohms—thermally the worst case for an amplifier with a class-AB or class-B output stage. At the end of that time the heatsinks were very hot, at 158.6°F (70.3°C). I usually precondition amplifiers for an hour, but I was concerned that the MC462 would get even hotter.
The McIntosh's voltage gain…
Wednesday April 24 and Thursday, April 25, starting at 5pm, Denver high-end audio retailer ListenUp (685 South Pearl Street, Denver, CO 80209, (303) 778-0780) is presenting its Music Matters 2019.

Jim Austin wrote about the Revel Ultima Salon2 in May 2019 (Vol.42 No.5):
Loudspeakers are the most diverse of hi-fi components, varying widely in conception, gestation, and morphology. This variety reflects the peculiar nature of our hobby, which spans the widest possible range of tastes, and of disciplines from science to art. Some loudspeakers are conceived to meet specific technical criteria, while others begin with a designer's loose idea and then evolve, via the trial and error of listening tests, to realize the designer's desired sound.
Far along toward the scientific side…
