Editor's Note: Class A "Loudspeakers" are sufficiently idiosyncratic and differ enough from one another that prospective customers should read Stereophile's original reviews in their entirety for descriptions of the sounds. I have therefore just listed every system or combination that at least one of Stereophile's reviewers feels, as a result of his or her experience, approaches the current state of the art in loudspeaker design. (Note that, to be eligible for inclusion in Class A, the system must be full-range—ie, feature bass extension to 20Hz. It must also be…

C. Crane FM Reflect Antenna: $34.95
The CCrane FM Reflect Antenna is a thick T-run of twin copper wires terminated by a 75 ohm connector. ST arranged it discreetly behind a closed window curtain, and used it to pull in all of his favorite HD Radio stations, including those his Sony XDR-F1HD tuner couldn't otherwise retrieve. "This is, by far, the best indoor FM antenna I have used, with or without HD Radio, and I am buying two more," he said. (Vol.32 No.4)

BSG qøl Signal Completion Stage: $2395
The qøl Signal Completion Stage is a remote-controlled, solid-state signal processor with four pairs each of RCA and XLR analog inputs and two pairs each of RCA and XLR outputs. With the qøl activated, JA invariably noted a larger overall sound, with a greater impression of the ambience surrounding performers, increased image depth, and better layering within that depth. From JA's measurements, it appeared the qøl process is basically a variant of the well-known Blumlein Shuffler technique. "You must audition the…

Sound Devices Model 722 portable audio recorder: $2775 ★
JM raved: "The coolest, most desirable piece of audio hardware I have encountered in a dog's age." The Model 722 is designed as a rugged, high-performance, foolproof, battery-powered portable stereo recorder for electronic newsgathering and video- and film-sound recording. However, with its line-level XLR analog inputs, onboard A/D converters, 40GB hard drive, and headphone amp, the 722 can also serve as a personal stereo. Offers 24-bit recording at up to a 192kHz sample rate. "The apotheosis of…

AI Technology ELGR-8501: $86.47/0.5oz.
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)

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…
