Oftentimes, when I see a piece of equipment that is highly stylized in form, I expect that function will not be up to par. Listening to Treble Clef Audio's TCA-M Signature active speaker ($103,900/pair) in room 1505 at AXPONA 2026 proved me wrong.

Shaped like a musical note, this Treble Clef Audio speaker (shown below) incorporates a host of cutting-edge technology: The transducer includes a folded dipole air velocity bass system—producing bass that radiates to the front and back eliminating sidewall reflections, linear-phase DSP crossovers, three integrated Pascal Class-D…

Playing a wild, assaultive Afro Cuban track, the Axiss Audio USA system in room 1628 at AXPONA 2026 practically shook the walls. Though the room didn't do the bass response any favors, the soundstage was well scaled, and imaging was strong, though at times a mite diffuse.

But this system also made me forget my critical listening hat and simply pulse, rock, and sway my old joints 'til they grew warm enough to resurrect the…

Audeze LCD-5: $4500
The open-back LCD-5 is the successor to Audeze’s well-regarded LCD-4 and, like its predecessor, uses planar-magnetic drive units, which feature proprietary, single-sided Fluxor neodymium N50 magnet arrays and a voice-coil concept called Parallel Uniforce. The idea is to vary the width of the conductor to match, or counter, variations in the magnetic flux to achieve uniform force across the membrane. The 90mm diaphragm is just 0.5 microns…

Analysis Plus Silver Apex Interconnects: $1219.99 (1m pair)
The Analysis Plus Silver Apex uses as its conductor an oxygen-free copper "stabilizing strand" covered with pure silver, in an arrangement the manufacturer describes, somewhat elliptically (haw) as "a hollow oval cable inside a hollow oval cable inside a hollow oval cable," said to be double shielded and thus quiet. And MF found it to be so: In his words, the Silver Apex is "highly recommended!" (Vol.42 No.5)

AC Nexus Advanced Power Distribution & Ground Enhancement System: $20,000
Steve McCormack, once the proprietor of The Mod Squad, is the man who introduced the concept of accessory isolation feet—his Tiptoes were aluminum cones with flat tops and sharply pointed feet.

The IEC AC inlet is a Bocchino Audio Marriner10 and the AC outlets are four Furutech Nano Crystal Formula duplexes. Four Cardas ground posts of…

"It's beautifully made, sonically transparent, performs a critical role in the optimal setup of subwoofrs, and has ergonomic bypass and mute functions that let you immediately hear the sonic iprovements of good bass management…

Acoustic Revive RR-888 Ultra Low Frequency Pulse Generator: $695
This small plastic box with a wall wart power supply is said to artificially generate the electromagnetic 7.83Hz Schumann resonance and alter the sound in your listening room. “Which it most certainly does—alter the sound, that is,” wrote AH. Listening to “Madness” from Miles Davis’s Nefertiti LP, he realized that the band’s tart, angular sound had become sweeter: “It was as though the dissonant and otherwise disagreeable sounds on the recording were somehow pushed down below the threshold of…
