Alta Audio Adam loudspeaker Page 2

Solidity and purity
It was time to play music. Levy mildly prefers solid state amps with the Adams, so I auditioned them using the three I had on hand: a Peachtree nova300, a recapped Krell FPB 200c, and an Anthem STR with onboard digital room correction. Sources included my Roon ROCK, a Naim Uniti Atom, and an Auralic Vega DAC run through the linestage of a Benchmark HPA4.

After the analytical/setup part of this review, the quick transition to right brain was pleasantly startling. I cued up Eva Cassidy's "Fields of Gold" from Live at Blues Alley (16/44.1, Tidal), and the…

Alta Audio Adam loudspeaker Measurements

Sidebar 3: Measurements

I used DRA Labs' MLSSA system, a calibrated DPA 4006 microphone to measure the Alta Audio Adam's frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield response of the woofer, both microphones used with an Earthworks preamplifier. For logistical reasons, I measured a different sample from those auditioned by Rogier van Bakel; its serial number was ADM2015.

No preferred listening axis is mentioned in the Alyssa's manual, but the center of the Adam's tweeter is 37" from the floor, which is close to the typical seated listener's…

Antal Audio, Triangle, Electrocompaniet, Wireworld

"There's a party going on in Room 713, and only true freaks are invited!" That's the promise of a bawdy little book called Room 713, about four friends who travel to another city and indulge in outsized carnal pleasures.

No such titillation was to be had in room 713 of the Embassy Suites in Tampa, but other delights abounded. To wit: a pair of Triangle Magellan Quatuor 40th-anniversary speakers ($20,000/pair), plus three Electrocompaniet components: the new AW 800M NEMO 2 monoblock used as a stereo amplifier (800W in mono, 300Wpc in stereo, $22,500), the EC 4.8 MkII preamp ($4900), and an…

High End By Oz, Lansche, Thrax, Hifistay, Rotel, S.I.N. Audio, Albedo

A real drum kit at the Florida expo? Standing in the second-floor hallway, I could've sworn I heard just that. Five seconds later, reality set in when Dave Brubeck's famous piano chords joined Joe Morello's 5/4 jazz groove. It was the recorded sound of Morello's drums on "Take Five" that had emanated from the Embassy Suites' Kennedy Room, where High End by Oz, a Connecticut distributor, was demoing its wares. (I sincerely love it when my brain gets tricked like that. The last time it happened was at the 2022 Pacific Audio Fest in Seattle, where the sound of a real piano came from the Joseph…

What I picked up at the Florida Expo 2023besides COVID

It was bound to happen sometime. The day after my return from the Florida Audio Expo, I tested positive for COVID. I'd worn a facemask on the plane, but not during the three days of pressing the flesh, listening, and reporting. (In fact, no one at the show did.) I suppose I paid for my lack of super-caution with several days of chills, headaches, violent coughing, and brain fog. This also accounts for the delay in getting the final batch of show reports out to you. Apologies!

In any case, COVID clearly isn't a thing of the past. Whatever your take on the whole issue, and however you…

A Funky Donald Byrd, Live from Montreux

At this point in the vinyl revival, it's hard to believe there are many undiscovered masterpieces left that are worth discovering. Record Store Day (RSD), a much-ballyhooed source of unique and unreleased music on vinyl, has been a major spur in the drive to plumb the vaults, but even though it has an excellent reputation, most RSD unearthings have turned out to be less than essential.

The increasingly rare exceptions are to be celebrated. Here's one. Just before the year turned to 2023, on what would have been Donald Byrd's 90th birthday, a smoldering, untapped artifact surfaced after 50…

CanJam NYC 2023 Commences

CanJams are about much more than skull-testing the newest headphones. They are the best places for all audiophiles to audition innovations in amplification, file servers, and digital converters and to jabber and bond with students, hipsters, gamers, and brainiacs from every part of the demographic spectrum. When the Jam is in New York, at the Marriott Marquis, it's like a being in a secret stadium lit neon-purple with white, vinyl-covered lounge chairs sheltered from the 100dB cauldron of Times Square tourism.

If you've only been to mainstream audio shows, you might be surprised…

Revinylization #39: New Reissues of Classic Ella and Billie on Verve and Decca

Decades after their deaths, Ella Fitzgerald and Billie Holiday loom large over the American music landscape, inspiring every jazz vocalist, especially the women. Fitzgerald and Holiday's contributions are vast, their work timeless, their joys and sorrows expressed in songs both thrilling and crushing.

Jazz as a form of popular song has largely faded from America's music culture, but Fitzgerald and Holiday's brilliance lives on, a beacon to their artistic excellence. Much evidence for that excellence can be heard in two new vinyl sets, both produced by Ken Druker.

Neither of these…
