Let's talk live recordings and audiophiles. While they may be semi-loathe to admit it, most genuinely possessed music fans, even including those with audiophile leanings, have live stuff or unreleased studio recordings that have been passed down to them via cassette tapes, MP3s, or CDs. After you buy everything that's been legally released and widely available, your curiosity naturally turns to finding what else is out there. And no matter what kind of music you like, there are a lot of killer bootlegs out there. On a trip several years ago to the Barcelona Jazz Festival, where the…
I spend my days comparing cartridges and speaker stands, arguing about imaging and microphone placement, speculating about DAC filters, and lately, sometimes, very secretly listening to headphones connected not to commercially available headphone amplifiers but directly to the outputs of basic tubed and solid-state power amplifiers. No person in his right mind would or should try this—it's too easy to destroy a pair of delicate, expensive headphones. But for me, it's been worth the risk.
My unauthorized experiments have been revelatory, and I have learned two things: 1) The sounds of…
And especially this 70-minute Bach CD. Using the Rogue RH-5 with Schiit Audio's Yggdrasil DAC, I played it all the way through, comparing its sound through the Susvaras to its sound through JPS Labs' Abyss AB-1266 Phis. The Susvaras were a smidgen more relaxed, which made these charming chorales sound slightly more artful and flowing. The music glowed with the Susvaras, but was better sorted and more corporeal through the Abysses. The Susvaras fully captured the atmosphere of the recording space, but the Abysses provided a more direct and intimate perspective that made Bach's counterpoint…
Back in May 2014, I reviewed NAD's Masters Series M50 Digital Music Player ($2499) and M52 Digital Music Vault ($1999 with 2TB storage). At the 2017 Consumer Electronics Show, NAD announced the M50.2, which is almost identical to the original M50 but now incorporates two 2TB hard disks, arranged as a 2TB RAID array, to ensure data integrity, and adds TosLink and coaxial digital inputs, Bluetooth with aptX for streaming music from a smartphone or tablet, and two single-ended analog inputs—all for $3999, or $499 less than the combined cost of the two earlier products. Like the M50, the M50.2…

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…
