Both musicians come out of a traditional, though modern, jazz vibe. Unlike some of their peers, such as Jason Moran and Vijay Iyer, who seek to redefine the piano trio in myriad ways, Hersch and Mehldau explore new pathways in song-forms, as the titles of these albums suggest—Mehldau underlining the core ingredients of jazz standards, Hersch nodding to Bill Evans' classic 1961 Sunday at the…

Two of the great jazz pianists on the scene have just released two of their greatest trio albums: Fred Hersch, Sunday Night at the Vanguard (Palmetto); and Brad Mehldau, Blues and Ballads (Nonesuch).
Simaudio saw disc-based digital audio in its rear-view mirror at least as far back as 2011, when it introduced the Moon Evolution 650D and 750D—two iterations of what it called a "digital-to-analog converter CD transport." These were actually multiple-input CD players, but Simaudio was evidently so eager to distance itself from the spinning disc that it went with a product category that, in spite of its cumbersome, run-on name, drew a clean line between the disc-reading and signal-processing functions—while bestowing upon the former second-class citizenship.

I downloaded the app and read the manual, but still had no idea how to integrate my hard drives into the network. Another call to Goodfield produced the answer, which was provided (sort of) in the list of MiND streaming capabilities. But really, a product like the 780D needs a manual that holds your hand, not a list of bulleted "capabilities"! I don't care if the dealer does the setup. Better that the customer learns how it all works, and how best to integrate sources into the MiND network. Don't you think?

Again, I won't try to describe something…

I measured the Simaudio Moon Evolution 780D with my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Source materials were WAV and AIFF test-tone files, played with Pure Music 3.0 on my MacBook Pro running on battery power. Apple's USB Prober utility identified the processor as the "MOON USB DSD HD AUDIO" from "SIMAUDIO LTD," and confirmed that the 780D's USB input operated in the optimal isochronous asynchronous mode. The AudioMIDI app indicated that the Simaudio DAC operated at all PCM sample rates from 32 to 384kHz, with a bit depth of up…
I am a big believer in supporting events promoted by specialty audio retailers. They reinforce the idea that audiophiles and manufacturers—even reviewers—are parts of a vibrant community that believes that listening to music with the highest possible quality is one of the more important things in life. The "Music Matters" evenings arranged by Audio Advice in North Carolina, Definitive Audio in Seattle, and Listen Up in Colorado exemplify that idea, and it was in April 2015, at Listen Up's Denver store, that I used a pair of PSB's new Imagine T3 tower speakers to play the audience some of my…

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the PSB Imagine T3's frequency response in the farfield, and an Earthworks QTC-40, which has a ¼" capsule and thus doesn't present a significant obstacle to the sound, for the nearfield frequency responses. I also used the Earthworks mike for the in-room response.
My estimate of the Imagine T3's voltage sensitivity was 89.2dB/2.83V/m, confirming the specified figure. The PSB's electrical impedance magnitude and phase are shown in fig.1. Other than in the regions between 28 and…
