Audeze The King: $3995
Created by legendary electronics designer Bascom H. King—geddit?—the hybrid tube/MOSFET The King headphone amplifier is built into a large (12.8" wide by 4.3" high by 11.8" deep) case supported by four substantial, shock-absorbing feet. It operates in class-A, and its two parallel, front-mounted, ¼" outputs can be calibrated by the user for…

DaySequerra FM Reference Signature Modification: $3200 (+ cost of tuner) ★
David Day's Signature Mod effectively addresses this ultimate FM tuner's cathode-ray tube's tendency to burn out. Switching circuitry has been added to allow the CRT to turn off when not needed. The Signature Mod also replaces the tuner's incandescent bulbs with longer-lasting LEDs, and uses hand-matched, low-group-delay filters for lower distortion and better channel separation. LG noted punchy, quick bass response, a deeper soundstage, and a more transparent midrange. "The new CRT's…

APC AV S15BLK: $730 w/battery backup ★
The S15BLK is a comprehensive power source, conditioner, and controller that features extensible external power and isolated EMI/RFI filtration for each of its outlet banks. Voltage regulation is accomplished electronically and without the hysteresis or rebound problems of slower, motor-driven compensation. Protected even the heaviest of KR's loads while also eliminating gray colorations and intermittent chassis vibration. "The S15 made the bridged eVo6 into an even better power amplifier—a super amp."

DEQX PreMate D/A preamplifier/equalizer: $4995
In a field where, as KR puts it, "all automatic EQ systems conflate speaker correction with room correction," the DEQX PreMate stands out: In use, this DSP engine begins by measuring and analyzing the speakers—in exclusion of the listening room, to the greatest extent possible—then generates filters to correct frequency response, optimize time alignment, and, if desired, create a customized active crossover for that speaker. After that, the user can, if he or she wishes, completely discard the speakers'…

AI Technology ELGR-8501: $160.75/1 oz ★
AI Technology's ELG-8501 is thermal grease made of more than 80% silver. JM uses a light smear on the mating surfaces of wall-wiring connections to prevent oxidation. He warns: "Never use any kind of silver paste on audio connections such as RCA plugs or amplifier speaker terminals." (Vol.36 No.10 WWW)

Atlantic Technology WA-5030: $399 ★
The WA-5030 wireless audio system comprises the WA-50-t, a transmitter module with USB and two-channel analog inputs; the WA-5030-r, a 30Wpc receiver with two-channel…

AcroLink 7N-DA2090 Speciale: $2375/1.5m pair
The less-than-snappily named 7N-DA2090 Speciale is technically laudable; commendably, AcroLink publishes the specs for this product's resistance (18milliohm/meter) and electrostatic capacitance (56pF/meter). It's made of 99.99999% pure multistrand copper, arranged in what AcroLink calls a "balanced twin core structure." According to MF, substituting the AcroLink interconnect for his TARA Zero Evolution "produced sharper but not unnaturally defined transients, shorter sustain and decay, and an overall well-detailed and more…

They were also expert at covering their contemporaries in the larger folk and rock worlds. From Bob Dylan's "Dear Landlord" to Leonard Cohen's "Suzanne," and even Chuck Berry's "Sweet Little Rock and Roller," this was a band that…

Just as the arc of the moral universe bends toward justice, the arc of commercial audio seems to bend toward conformity. Nowhere is that more apparent than in the loudspeaker industry, where many once-great manufacturers—great inasmuch as they designed breathtakingly original products, built them to the highest levels of quality, and thus created not only community jobs but also a justification, other than hollow jingoism, for community pride—now exist only as oft-traded names affixed to reflex-loaded…
