Sidebar 3: Measurements
The NAD M50.2's analog inputs have an impedance of close to 20k ohms, and the analog input signals appear to be converted to 24-bit digital with a sample rate of 48kHz. Playing a 1kHz, –20dBFS tone from Editor's Choice (CD, Stereophile STPH016-2) on my Ayre C-5xeMP player, which has a maximum single-ended output level of 2.1V, resulted in digital data with a maximum level of –21.35dBFS. The gain of the M50.2's analog inputs will work well with sources that don't peak above 2V RMS. The resultant digital-domain spectrum (fig.1) had a clean noise floor, with the…

This review began when I ran into Gary Yacoubian, president of SVS, in a crowded hallway at Las Vegas's Venetian Hotel, during the 2016 Consumer Electronics Show. He smiled and introduced himself. "Larry, I enjoyed your review of our SB13-Ultra. If you liked that subwoofer, we have something coming soon that should really interest you. I can't say anything more now."
He'd gotten my attention. But it wasn't until the next year's CES that I learned about SVS's newest and largest subwoofer, the SB16-Ultra, which deploys a 16" driver and a radically different magnet structure, voice-coil…
SVS's Merlin—a portion of the company's website that offers loudspeaker-specific recommendations on SVS subwoofers and settings—recommends low-pass filter settings of 60Hz (high-pass) and 40Hz, 12dB/octave (low-pass). Because the CR-1 couldn't use different slopes for high- and low-pass filters, I set its high-pass filter at 60Hz, 24dB/octave for the Quad ESL-989s, and the SB16-Ultra's internal low pass filter to 40Hz, 12dB/octave. I then used the SVS app's parametric equalizer to reduce peak room modes at 43 and 160Hz, and played the same recordings as before. The integration of the sub's…

John Atkinson asked me to review the dCS Network Bridge ($4250), which was designed to be paired not just with the dCS Vivaldi DAC ($35,999) running the current v.2.02 software, but with any DAC. This meant I was forced to endure several months with the state-of-the-art Vivaldi as a replacement for my reference dCS Rossini ($23,999). Oh, how I suffered.
Michael Fremer, in his January 2014 review of dCS's four-piece Vivaldi system ($114,996), of which the Vivaldi DAC is part, called it "the best non–digital-sounding digital system I've heard." John Atkinson, in his measurements for that…
After everything settled in, I used the Bridge app to play the first movement of Lou Harrison's Concerto for Violin with Percussion Orchestra, with soloist Tim Fain and Angel Gil-Ordóñez conducting the Post-Classical Ensemble (24/48 WAV, Naxos 8.559825/HDtracks). The Bridge-Vivaldi combo painted the solo violin and percussion with far more believable body and substance than I'd heard before, at home or at audio shows. Textures of drums, gongs, and chimes were far more realistic and transparent, with copious air around percussion. I was astounded by the percussion's lifelike visceral impact…
