I measured a different sample of the PREi from that auditioned by Jason Victor Serinus; mine had the serial number PRO37. I used my Audio Precision SYS2722 system to perform a complete set of tests using both the PREi's balanced and unbalanced inputs and outputs.

The PREi preserved absolute polarity (ie, was noninverting) with all the inputs and outputs. (The preamplifier's balanced XLR jacks are wired with pin 2 hot, the AES convention.) The volume control operated in accurate 0.5dB steps, and with this control set to the maximum of "+6dB," the gain was 5.…

On January 12, 2026, Dan D'Agostino Master Systems (DDMAS) welcomed approximately 52 international audio dealers and distributors, along with four members of the audio press, to the unveiling of the new Momentum Z mono amplifier ($125,000/pair) at the Dan D'Agostino factory in Cave Creek, Arizona. This 15th Anniversary event included: a fabulous welcome dinner in the finest and most sophisticated "steakhouse" I've ever visited (not that I've visited many); an extended product…

The last time my head turned when a recording received "Best of Month" notice from several magazines was in 2023, when Warner released Antonio Pappano's Turandot. The time before that was 26 years ago when Sony released pianist Murray Perahia's spiritually…

One hundred and fifty years after his birth, the music of visionary American composer Charles Ives has gained a degree of public and critical acceptance, but even that acceptance has seemed confined to orchestral works, especially The Unanswered Question and Three Places in New England. One of his thorniest compositions, the stunning…

Sometimes, great components enter our lives with little fanfare. Thus, by happenstance, did Lamm Industries' L2.1 Reference preamplifier ($22,790) end up in my reference system.

The story began at the 2018 Consumer Electronics Show, in Las Vegas, when John Atkinson and I visited Lamm's oversize suite on a high floor of the Venetian Hotel. Our intentions were twofold: to report on what we heard and saw, and to sniff out products for me to review. We found one likely candidate—AQ…

After two-and-a-half years with Wilson Audio's Alexia serving as my reference loudspeaker ($52,000/pair), I was eager to hear the differences between it and its successor, the Alexia Series 2 ($57,900/pair). My first serious listen to the Alexia 2 speakers took place at Definitive Audio Bellevue, before my review samples arrived. That system's dCS Rossini DAC and clock, D'Agostino Progression stereo amp, and Transparent Audio cables and interconnects were sonic familiars, but Definitive's music collection was…

For her first proper full-length, British-born Iranian composer/performer Shiva Feshareki set her ambitions high, reaching up into the ether and backward into the early days of electronic music.

Feshareki has garnered acclaim for her live mixing of electronic and acoustic sounds. On the…

I had just met Steve. We sat across from one another at a table full of hi-fi enthusiasts, salesmen, writers, and family, where we enjoyed fine wine, pizza, and conversation. Steve…
