LATEST ADDITIONS

The musical and technical excellence of the 2016 Grammy Award winners makes this a great year for audiophiles. Not only are 28 of the albums / compositions that won awards in multiple categories available for download from HDTracks, virtually all in hi-rez (from 44.1/24 to 192/24), but just as many if not more are available for streaming and download in hi-rez and/or full CD quality from both ClassicsOnlineHD and Tidal.

When the Record Industry Association of America adopted its standard disc playback equalization curve in 1954, hi-fi enthusiasts heaved a sigh of relief and bade fond farewell to years of confusion, doubt and virtual pandemonium. Before the RIAA curve there were six "standard" curves in use, and since nobody seemed to know who was using what, getting flat response from a disc was often more a matter of luck than anything else. The adoption of the RIAA standard playback curve heralded an end to all this.

The $800 JVC XL-Z1050TN 1050 is the Bitstream successor to JVC's popular 18-bit XL-Z1010, which got an enthusiastic thumbs-up from Robert Harley in April 1990 (Vol.13 No.4). Its styling is, in my opinion, much improved over the older player's, with the distinctive brushed-bronze finish of the rest of JVC's XL-Z line. The rear panel sports fixed and variable outputs (footnote 1), as well as Toslink optical and coaxial digital outputs. As with the 1010, the JVC features their proprietary K2 Interface, a circuit that reduces jitter by resampling the pulses with a short-duration gate just ahead of the single-bit JVC JCE-4501 DAC chip.

Metronome’s CD8 S, which adds digital inputs to the French company’s well-regarded CD player, graces our March issue’s cover. As is often the case these days, we loved the sound but hated the measured performance—madness indeed! Melco’s affordable server and Merging’s expensive network-connected NADAC multichannel D/A processor get our nod of approval, as do class-D amplifiers from Theta, NAD, and Spec, while Herb Reichert finds much to enjoy with Simaudio’s Moon Neo 340i integrated amp. And on the music side of things, Robert Baird praises Acoustic Sounds’ new stereo releases of classic Beach Boys albums and John Atkinson reacts to a recent report that classical music recordings will soon disappear. That would be madness!

Everyone in the room can hear the difference when I swap one phono cartridge for another. Same thing happens with loudspeakers. This is because both of these magnet-based transducer technologies are electromechanical devices, traditionally made of paper, wood, iron, and copper. (Nowadays, polymers, aluminum, and carbon composites are more typical.) Both are motor-generator mechanisms that either convert mechanical energy into electrical energy (cartridges) or vice versa (speakers). As audio devices, they are spool-and-wire simple, but even tiny changes in the materials and/or how those materials are configured can cause easily audible differences in how they transmit or present recordings of music. Why? Because every gross fragment and subatomic particle of these electromechanical contraptions is moving and shaking—shaking everything from the tiny jumping electrons to the wood, metal, and/or plastic containers that fix and locate these motor generators in space.

For some time now, I've been thinking that my record player was due for an upgrade. My Linn LP12 turntable and Ittok LVII tonearm are about 25 years old, and my AudioQuest AQ7000nsx cartridge is going on 15. During that time, my listening has become increasingly dominated by CDs, but I am not yet ready to give up on LPs. Updating my LP12—for which I have Linn's Lingo power supply but no other upgrades—would involve installing the Keel subchassis, for $3250—for which price I could get another maker's new, current-design turntable and still have the LP12 to sell. The Linn Ittok can't be upgraded, and its replacement, the Ekos SE, costs $4950—out of my range. AudioQuest no longer makes cartridges. Examining my AQ7000nsx's stylus under a microscope showed no visible wear, and there was no obvious audible problem that could be traced to the cartridge's suspension, but age must be having some sort of effect. Taking all these factors into account, I decided to replace my entire phono front end.
