Stenheim Alumine Two.Five loudspeaker

Stereophile has favorably reviewed three loudspeakers from Swiss manufacturer Stenheim. Art Dudley reviewed the Alumine standmount in April 2012 and the Alumine Five floorstander in March 2018. More recently, Herb Reichert reviewed Stenheim's three-and-a-half-way Alumine Three tower in October 2021. My assignment for this month's issue was to review the company's Alumine Two. Five floorstander, which, at $23,500/pair, fits neatly between the Alumine Two ($13,500/pair) and Three ($36,500/pair).

Boulder 1151 monoblock power amplifier

For several decades—from well before I toured the Boulder factory in 2016—I've wanted to get a handle on the best sound the now–41-year-old company can offer. Multiple listening sessions at shows had more than hinted at excellence. But neither my time in Boulder's large, dedicated music room, which was intentionally dry, nor exposure at various hi-fi shows left me convinced that I'd heard Boulder's full potential.

My first opportunity for an in-home audition came in 2021, when I reviewed the 866 stereo integrated amplifier ($17,500 with DAC, $16,000 without). But that entry-level (by Boulder standards) product, which Senior Engineer Jameson Ludlam said was released to build brand awareness and expand the company's reach by offering "a more accessible product that provides the features we think many people are looking for with the performance they have come to expect from Boulder," only provided a peek at the excellence I expected Boulder to achieve.

So when a last-minute review cancellation opened space to review the just-released Boulder 1151 mono power amplifier ($47,000/pair), I thought, "At last!"

An AudioQuest Cable Loom: Vodka network, Pegasus interconnects, Robin Hood speaker cables, Blizzard power cables

I began the test series I discussed in Colloms on Cables with the first company to respond to our request for review samples: AudioQuest. Their loom comprised a pair of Robin Hood Zero loudspeaker cables; Pegasus I/C interconnects, both unbalanced RCA and balanced XLR; Blizzard AC power cables; and Vodka Ethernet cables. AudioQuest has decades of experience with audio cables, supplying a huge range from high-quality "industrial" cables—some available in bulk for custom-install applications and manufacturing—to more familiar audiophile constructions. Their designs are highly finessed and exquisitely terminated, some executed in exotic materials, particularly solid silver. An established bedrock of engineering underlies AudioQuest's cables. They're based on high-quality, nontwisted conductors, low-loss insulation materials, well-known construction geometries, and a nuanced approach to subtler aspects including conductor purity and cable-draw finish.

Colloms on Cables

Underpinning a discussion about the merits of potentially costly specialist audio cables is an obvious question: Why do we need them? Doesn't almost all wire conduct audio signals with negligible distortion and very little loss of power? Specialist hi-fi cables seem expensive for what you get. Especially at the upper end, they seem like a worse value than electronics and loudspeakers. Depreciation is greater, too: Cables are almost a consumable.

But if you wish to finesse the quality endeavor of classic separates-based hi-fi systems, you cannot do without them. Fundamentally, it is not the efficient transfer of audio power that's the issue; that is the easy bit. Rather, it is a matter of optimizing the transmission of the more subtle information that describes recorded acoustic, instrumental detail, the performers, and, not least, dynamics and rhythm: Are your feet tapping unconsciously in time to the performance?

Re-Tales #54: Fidelity Imports Stays True to its Passions

Photo by Mark Henninger

Steve Jain, cofounder and managing director of Fidelity Imports, has been busy since launching the company six years ago in the Philadelphia area. In recent months, Fidelity has added two brands to their roster; they now represent 16 high-performance audio companies. Maintaining his early passions helped fuel his drive to start a business and continue its expansion and innovation—aspects Jain believes differentiate Fidelity Imports from the competition. "I constantly want to keep trying to innovate and keep us ahead," Jain told me in a recent conversation over Zoom.

Gramophone Dreams #97: Jamming With Cans at CanJam NYC

Most of what I know about audio I learned from drag racing. That's where I first recognized the relationship between force, geometry, and sound. When I was barely out of high school, I began consciously picturing sounds as a symphony of forces operating in a Cartesian space. In retrospect, this "Cartesian picturing" was probably inspired by the descriptive geometry class I was taking at Wright junior college in Chicago, but I didn't think of that at the time.

Why Hi-Fi Prices Have Risen

I wrote much of this column, including the title, in early April before the Trump administration announced "reciprocal" tariffs on imported goods. A random example: Switzerland, home of CH Precision, darTZeel, Goldmund, Orpheus Lab, Piega, Stenheim, Thorens, and Wattson, among other hi-fi companies, where the tariff is 31%. Before this issue closed, the Trump administration announced a 90-day reprieve for everyone but China, then exempted computers and smartphones (and a few other categories) from the China tariffs. Importers and foreign manufacturers I talked to at AXPONA in April were happy for the reprieve but remained on edge. Uncertainty reigned.
