Would it be damning this cartridge with faint praise to simply call it nice? I hope not, because that's precisely what the entry-level model from Mobile Fidelity Electronics is. That's not to say inoffensive, as in competent but not particularly inspiring. The StudioTracker is, in fact, fairly sophisticated and affable for such an inexpensive example... Read More »

Six years have passed since Stage III Concepts introduced their Medusa Speaker Cable, which the brand distributor claimed to be the world's first with a vacuum dielectric. This was no ordinary wire product. I gave it a Writers Choice Award in 2016. The Cerberus Speaker Cable, a new top model in the vacuum line, followed... Read More »

When something is not as advertised, I have no problem calling it out. So it was when music streaming came along. I read reviews, heard the demos, and my ears told me it was a step backwards, plus it was always crashing. I stayed on the sidelines until about four years ago when my DAC... Read More »

Its utilitarian industrial design bears a striking resemblance to the Threshold 300 Stasis designed by audio guru Nelson Pass, which should come as no surprise. In 1972 Usher Audio's owner and head engineer Lien-Shui Tsai built the first Usher R-1.5 amplifier as a copy of... Read More »

Together in Bits and Pieces. First Bit. The least expensive way to get great sound out of your system is to "cheat." Don't buy new gear, buy really well recorded music. The sound your system exhibited with pedestrian recordings will now sound much better, because the source is literally better. This is no joke. Sure,... Read More »

Staring out from the darkened hotel room, two sculpted, burly figures stand guarding the glistening golden and onyx tinted treasures between them. Suited in matching, high gloss Macassar Ebony with piano black faceplates angled back and studded with a tweeter and two drivers, at nearly four feet tall, they can swing and punch with the...

Last Sunday marked a return to Town Hall, New York City, for a concert by ECCO (the East Coast Chamber Orchestra), a group of 18 youthful, professional string players. These guys (actually, most were female and Asian) were really digging in, using the full bow when they had to and, alternately, approaching near silence in... Read More »
