Gramophone Dreams #57: Ferrum OOR headphone amplifier and HYPSOS power supply

Herb Reichert First Published: Feb 01, 2022
I'm deep into audio power amplifiers because they remind me of race car engines. Both power sources are wildly inefficient, converting only a small percentage of their stored energy into work while dissipating the rest as heat and vibration. Mainly though, I love how race car engines sound. How they shake the air. Just like amps and speakers.

iFi ZEN CAN headphone amplifier & ZEN DAC Signature V2 D/A processor

Julie Mullins First Published: Dec 31, 2021
It had been a while since I'd done any serious, critical listening through headphones. That changed when Editor Jim Austin asked if I wanted to review the iFi Audio ZEN Signature Set ($599). Figuring I could use more Zen in my life, I agreed.

UK-based iFi Audio, which operates under the auspices of the Abbington Global Group, has released several compact products in its ZEN series: DACs, headphone amps, a Bluetooth receiver, and a network streamer.

Gramophone Dreams #56: Woo Audio 3ES preamplifier/headphone amplifier and Audeze CRBN electrostatic headphones

Herb Reichert First Published: Dec 23, 2021
At noon on a cloudless, ridiculously bright 97° day, John Atkinson and I auditioned Audeze's new-but-not-yet-released CRBN electrostatic headphones. The audition took place at a sneak preview hosted by Audeze's principal, Sankar Thiagasamudram, in a sleeping room at New York's hipster-chic Ace Hotel on 29th Street and Broadway.

Gramophone Dreams #53: RAAL-requisite HSA-1b headphone/loudspeaker amplifier

Herb Reichert First Published: Oct 06, 2021
Today is Monday. Since Saturday, I have changed the amplifier driving my Falcon Gold Badge LS3/5a speakers three times—from the Parasound Halo A21+ (250Wpc into 8 ohms) to the Pass Labs XA25 (>25Wpc into 8 ohms) to the Elekit TU-8600S (9Wpc into 8 ohms). Now I am listening to the Falcons via the just-arrived RAAL-requisite HSA-1b headphone and speaker amplifier. This unusual, made-in-Serbia amp is priced at $4500. It's specified to produce 10Wpc into 8 ohms, 20Wpc into 4 ohms, 40Wpc into 2 ohms, and 55Wpc into 1 ohm, these values from the loudspeaker output

Gramophone Dreams #52: Naim Uniti Atom Headphone Edition & Focal Clear Mg headphones

Herb Reichert First Published: Aug 24, 2021
One summer afternoon in Brooklyn, after a sweaty too-long day doing construction, I stumbled upon a hi-fi shop I'd never noticed before. I thought, hmmm, I bet they have air conditioning.

Inside, the air was only marginally cooler, but before I could leave, an excessively happy salesman introduced himself. After a bit of low-level chit-chat, he asked me if I was into British audio. I told him I "Never heard of it."

Schiit Audio Vali 2+ headphone amplifier

Herb Reichert First Published: Apr 21, 2021
In Schiit's words: "Measurements, schmeasurements! If you want measurements, we got measurements: the Magni Heresy's got you covered. But if you're ready to have some fun with something completely different, Vali 2+ is for you. Enjoy tube sound without tons of noise, play with different tubes without having to get a second mortgage for a matched quad, and see what this whole tube thing is all about!"

John Atkinson First Published: Feb 15, 2021
When Stereophile publishes a followup review in the print magazine, we add it as a "child page" to the website reprint of the original coverage. We have recently done so with three significant products: the Magico M2 loudspeaker, the Linear Tube Audio Z10e tubed headphone amplifier/integrated amplifier, and the Okto Research dac8 PRO multichannel D/A processor.
