Like many audiophiles with limited space and limited funds, I often wonder why, at audio shows, so many companies insist on displaying ultra-expensive systems. Why not real-world systems that most people can afford? Systems they can use in day-to-day living spaces, not just man caves?

Two years ago next month, in a feature for sister site SoundStage! Hi-Fi, Doug Schneider posed a question: “Is it time for active speakers?” As Doug noted, audiophiles have traditionally been cool toward active designs, despite their many advantages. This is partly because active speakers take some of the fun out of hobbyist audio. Audiophiles want to choose their own amps and cables, rather than have someone else make those choices for them.

Keen-eyed readers may have noticed that I recently added a new category to the Associated Equipment section at the end of my reviews. In addition to listing the speakers, sources, and cables used for a review, I’ve started listing my network setup. For most of the products I review, every note I listen to is streamed over a network. That makes the network an important part of my home-entertainment system.

It’s a common fallacy to believe that things that come easily to you come easily to everyone. But as a recent experience confirmed for me, it’s just not so.

This fall marked the 10th anniversary of file-based, high-resolution audio playback. The New York City-based website HDtracks opened its virtual doors in March 2008; in October of that year, it added to its catalog 24-bit/88.2kHz and 24/96 FLAC files.

One of my pet peeves is technology that thinks it knows more than I do. Sometimes, software developers will release a new version that removes a useful feature, supposedly to enhance ease of use, but usually to advance a corporate agenda. Sometimes, they’ll streamline a key function to make it simpler for inexperienced users, at the cost of restricting flexibility for experienced users.

Sometime soon, hopefully before the end of 2018, North American audiophiles will have their choice of two high-resolution music-streaming services. One of them is a familiar name -- now available in 57 countries, Tidal has been operating in North America since 2015. The other is a relative unknown, at least on the west side of the Atlantic.
