The company also demonstrated the Heritage La Scala AL6 loudspeaker with its optional La Scala Active Crossover. According to Klipsch, the active crossover enables system flexibility, precision tuning, and increased dynamic range. The La Scala AL6 carries an MSRP of $15,399/pair, with the active crossover priced at $3499.

During the past decade and a half, the trips I've taken have tended to be for magazine stories. I love to travel, but as a New Yorker living on a writer's income, I figure it makes more sense to do it on someone else's dime and stay in nicer places than I could afford otherwise. The downside is that these trips don't feel like vacations, or even particularly restful: My time tends to be taken up with interviews, overly elaborate meals eaten (or tasted) in the company of chefs and winemakers, weeks when I…
When I checked my amplification for hum and standing noise, everything was at or near what I considered "spec" for zero-feedback tube amps. Apparently those specs needed revising. Meanwhile, I was fascinated by how a very sensitive speaker could show…
I used my Audio Precision SYS2722 system to measure the Eversolo AMP-F10. I performed a complete set of tests in Stereo mode, then repeated some of the tests with the two channels operated in Bridged Mono mode. I preconditioned the amplifier at 1/8 the maximum power into 8 ohms for 30 minutes before starting the testing. At the end of that time, the heatsinks were almost too hot to touch, at 139.1°F/59.5°C. The top panel's temperature measured 108.5°F/42.5°C. This amplifier needs plenty of ventilation.
Looking first at the Eversolo's behavior in Stereo: The…
I performed a full set of measurements on the Weiss DAC204 using my Audio Precision SYS2722, repeating some of the testing with the magazine's higher-resolution APx555 analyzer. I used optical and coaxial S/PDIF data—the TosLink input accepted data sampled at rates up to 96kHz—as well as USB data sourced from my MacBook Pro. Apple's USB Prober utility identified the processor as "xCORE USB Audio 2.0" from "XMOS" and indicated that the USB port operated in the optimal isochronous asynchronous mode. The AudioMIDI utility revealed that the 204's USB port accepted 16-…
