One of several small, wireless speakers unveiled at the Venetian Hotel, Audioengine's A2+ ($269/pair), with built-in DAC and aptX Bluetooth, is manufactured in China, and scheduled to ship at the end of January. I didn't get a chance to hear the A2+, but our niece, who has the wired version, raves about its sound with her Mac laptop.

Although I no longer attend the audio pageant that was once the annual Consumer Electronics Show, I now seem to be traveling more, in hopes of recapturing the excitement CES had once provided. Last May I attended High End, in Munich, and found that while it was entirely as advertised, there was, alas, not enough emphasis on the playback of high-resolution files, and hardly any attention paid to multichannel music.

As a longtime user of Nordost's cable and AC-power products, my ears opened wide when they released their three QKore Ground Units and QKore Wire at High End 2017, in Munich. While I've never questioned the importance of proper electrical grounding, to prevent problems with safety and noise—the latter including measurable noise generated by transformers, appliances, LED lighting, power supplies, and Bluetooth, WiFi, and cellular devices—I couldn't fathom what difference a passive grounding device might make in a high-end system that, in my case, is fed by an 8-gauge dedicated line with its own copper ground rod driven into the terra infirma of the fault-ridden Pacific Northwest.

After a few minutes in the VTL/Wilson/Nordost room on the 29th floor of the Venetian Hotel, the challenge I faced in covering CES 2019 was staring me in the face. The good news for me, and the bad news for exhibitors, was that visitor traffic was extremely light. To only two rooms did I need to backtrack because exhibitors were totally occupied with other visitors when I paid an initial visit. But, on the other hand, the sound in some rooms was so good, the musical selections so compelling, and the exhibitors so hungry for attention from someone that I had an extremely difficult time tearing myself away and moving on.
