Because of their extraordinary focusing and structuring talents, both speakers—the Acelec and the TAD—shared a knack for making me pay attention to, and oftentimes enjoy, music I did not appreciate previously.

One such piece, Richard Strauss's Metamorphosen, TrV 290, performed by the recently formed (2018) Sinfonia Grange au Lac, conducted by Finnish conductor/composer Esa-Pekka Salonen (24/48 FLAC, Alpha Classics/Qobuz), drew me all the way in and held my attention all the way through. This never would have happened with a lesser speaker. With the Acelec Model Ones, the…

I used DRA Labs' MLSSA system with a calibrated DPA 4006 microphone to measure the Acelec Model One's behavior in the farfield and an Earthworks QTC-40 mike for the nearfield responses. I measured the speaker's impedance magnitude and phase with Dayton Audio's DATS V2 system.

The Model One's specified sensitivity is 84dB/W/m; my B-weighted estimate was within experimental error of that figure, at 84.1dB(B)/2.83V/m. The Model One's nominal impedance…

After entering the music scene with Lionel Hampton's late-era big band as a trumpet player and arranger, Q moved to New York City and landed gigs arranging for Ray Charles, his childhood friend and surrogate big brother, and other jazz and pop artists including Dinah Washington. His work with Washington brought him to the attention of Mercury/…

Audio engineers never get the credit they deserve. The same is true for music arrangers, who are also an unheralded but hugely fundamental part of any musical success. As a composer, conductor, and inventive arranger of popular music, the modest but multitalented Vince Mendoza says he's most focused on enhancing the song he is arranging and the story it is trying to tell.

"Young arrangers are very concerned with their own voice and spinning their own melodies and turning things upside down and backwards, and they forget what a song really is about," he told me…

HiFiMan's wood-cup mania
I've been using two very different HiFiMan headphones: the newer, $1999 Audivina, which was released in March 2023, and the older HE-R10P, which costs $5499 and was released in spring 2021. Both are wood-cupped closed backs with "Supernano" planar-magnetic diaphragms. Each time I use one of them, I pause, surprised again by how just right it sounds. ("Just right" is an audio descriptor that needs no explanation. You'll know it when you hear it, I promise.)…

The vectors of tradition, originality, and talent came together in Jones to produce a strange and unlikely gift. His music can make you feel things as suddenly and deeply as just about anyone's, but on top of this Jones had the greatest…
