For logistical reasons, I measured a different sample of the Volti Audio Razz (serial number V1, 007) to those auditioned by Tom Gibbs. (There wasn't a grille supplied with this sample.) I measured the loudspeaker's farfield behavior with DRA Labs' MLSSA system and a calibrated DPA 4006 microphone. I used an Earthworks QTC-40 mike for the speaker's nearfield responses. I repeated some of the testing with Dayton Audio's OmniMic V2 and DATS V2 systems.

Volti specifies the Razz's sensitivity as "97dB." My estimate was 93dB(B)/2.83V/m—while this is lower than…

Nothing about Alice Phoebe Lou's musical career reflects industry norms. She maintains complete control over every aspect of her work, from creation to release. The result is always original and fascinating. Lou is at her best when she has an…

As it happened, yes it was a coincidence. True, my music was pretty loud, and the bass from the Piega Premium Wireless 701 loudspeaker system ($7495/pair) was anything but reticent, especially considering the tower's sleek appearance. But I was not the source of the specific noise that caused the complaint. That was the sloppy bass from another neighbor's inferior sound system. (The bass from this Piega system isn't sloppy.)

And yet, when…

I first looked at the behavior of the Piega Connect wireless control unit, using my Audio Precision SYS2722 analyzer. Measured at its analog output jacks in variable mode, this had a maximum gain of 0.3dB. The fixed mode offered the same 0.3dB gain. The analog input clipped at 2.2V. A 1kHz signal at –12dBFS at the coaxial and optical digital inputs resulted in a level at the analog outputs of 534mV, suggesting that the Connect's gain architecture is very similar for both analog and digital signals. Both digital inputs locked on to data sampled at rates from 44.…

I chose the Sphinx because it was a hybrid tube–class-D design that, to my ears, blended French-wine tube flavor with the grip and authority of class-D solid-stateness. The Sphinx was proletariat, not patrician, but it still showed me the merry music of Paris during La…

The Sphinx V3's MM/MC phono input did proclaim the virtues of analog.
