When I recently reviewed Yamaha’s R-N803 network stereo receiver ($749.95 USD), one highlight turned out to be the company’s Yamaha Parametric Acoustic Optimizer (YPAO) room-equalization software, which I found benefited the sound. YPAO has long been a feature of Yamaha’s A/V receivers, but the R-N803 marked its debut in a stereo receiver. Which led me to wonder: Why had it taken so long? It also got me wondering: Why there aren’t more stereo-only products with room-correction software?

Careful listening to recordings is by its nature a solitary experience. That’s why audiophiles have a rep for being loners -- you can’t fully soak in the nuances of great music unless you’re focused on listening, and that requires both concentration and a degree of isolation.

Hegel Music Systems’ Röst ($3000 USD) was the first integrated amplifier to be reviewed on SoundStage! Simplifi, and to this day it’s a benchmark that other integrated amps must measure up to. That situation might seem odd when you consider that some models we’ve reviewed in the past few months have clearly outpaced the Röst in such features as Roon readiness, DSD support, and MQA decoding, all of which the Hegel lacks. The Röst also has no control app -- another amenity that manufacturers typically make available for network-capable products. What is it about the Röst that makes it special?

The 2017 edition of the Custom Electronic Design & Installation Association’s annual exposition, formerly called the CEDIA Expo but now simply CEDIA, took place in early September at the San Diego Convention Center. Though CEDIA is ground zero for networked audio, most of the products displayed this year were in-wall and in-ceiling speakers connected to multizone amps operated by proprietary, keypad-controlled, home-automation systems. In other words, CEDIA was packed with gear designed to be heard, not seen -- products mainly of interest to custom-installation professionals. Since the dawn of Sonos, however, a stream of consumer-oriented products have popped up amid the aisles of nondescript hardware, and virtually all of it -- mostly streamers and speakers -- uses wireless technology. Much of it is affordable, simple to install, and can run on a home’s Wi-Fi network. Here are the most interesting products I spied while roaming the aisles of the SDCC with my Simplifi goggles on. All prices are in USD.

Ah, Munich in the spring. Strolling the banks of the Isar. Pedaling a boat across the Kleinhesseloher See (a lake) in the English Garden. Then, to wind down the day, hoisting a stein in the biergarten of the Augustinerkeller.

Once a business with an all-you-can-eat model, media streaming has begun to carve out niches to serve more narrowly defined interests. Take Disney, which recently announced that it would pull its content from Netflix to create its own streaming platform aimed at parents of young children who eagerly consume Disney and Pixar movies. Then there’s FilmStruck, a service created by Turner Classic Movies and the Criterion Collection to stream their catalogs directly to equally eager cineastes.

Each of the seven vices can be committed by the record collector -- even sloth, which is the sin of not taking proper care of your LPs, or of failing to file them correctly. But the vice I’ve come to most closely associate with collecting vinyl is greed.
