Classic Sound with Streaming Smarts

Integrated amplifiers equipped with on-board streaming facilities and software, and the requisite digital-toanalog conversion hardware, have taken the place that the stereo receiver once held, back in the 1960's, '70's, and '80's. They are today's entry-level drug to the world of serious music repro, just as network streaming has become the agent of music discovery, the role played by alternative FM radio back in the day. (Though we didn't have algorithms to pick tracks for us....)

Technics' new example, the SU-GX70 Network Audio Amplifier, thus announces its function right in the name. Technics, the seriousaudio brand of mega-manufacturer Panasonic, has an illustrious history. Most notable for its direct-drive turntables accepted as the standard by generations of DJ's, the brand has also produced most every important class of audio component at one time or another, before Panasonic retired the name around the beginning of this century.

Panasonic elected to revive the Technics brand about a decade ago, and has produced a select few decidedly high-end-oriented designs since, of which the SU-GX70 is the latest. The new amp boasts a deep list of high-tech bona fides, including something they call a Jitter-Elimination Noise-shaping Optimization amplifier (JENO), which as best I can tell is a proprietary Class D amp incorporating substantial noise-shaping (Technics shows its clock frequency as 368 KHz). JENO is claimed to be "...less susceptible to signal degradation caused by external noise, ensuring more precise signal transmission.Accurate signal processing not only delivers high-resolution digital audio but also maintains the soft texture inherent in analogue recordings." Uh, whatever. I also discovered an unexpected room-EQ system, and a speaker-phase-correction tech the firm labels LAPC, both of which are discussed a bit further on.

The Big Clean

Chances are you probably do not think about the state of your electronic devices too often. Oh, you might think about all the upgrades you would like to make; where you would put those new tower speakers, or how a second or third subwoofer would really tame those bass modes in your room, or how much more cinematic a larger screen would be. Sure, you think about that part of your system. But how often do you think about the well-being of your system?

Bridging the Analog-Digital Gap on a Recliner

When I shopped for a motorized recliner, I rejected models with their own Internet Protocol address and built-in speakers. No need. I had already placed a smart speaker on an étagère beside the space where I had planned to put the chair. I'd have a smartphone in my hand and the room would be bathed in Wi-Fi.
