In red letters on the first page of Chinese audio manufacturer Audio-GD's website are these words: Wisdom in mind, enthusiasm at heart.

I like this goodwill greeting because it sets a mindful tone. I presume that sentiment was issued by one Mr. He Qinghua, because farther down the page, it states, "All Audio-GD's products are designed and developed under the leadership of Mr. He Qinghua." When I began my auditions, I took this salutation as an advisement, making it my plan to study Audio-GD's Vacuum HE1 XLR line-level preamp with as much wisdom as I could muster and the enthusiasm of high expectations.

Hi-fi is at a crossroads. One road takes us toward modernized versions of the gear we grew up with, stuff that has been around since the 1950s. The other road faces the future. While sometimes accommodating physical media, including vinyl records, that's not where that road leads. On that road, streaming is the norm, and equipment may be hooked up with traditional signal cables or with no cables at all, just GHz-range electromagnetic radiation, the digital kind. In the more extreme cases, the music may remain digital all the way to the amplifiers, which themselves are likely to be class-D.

I keep a foot on both paths, hoping they don't diverge so much that they split me in two. I've got a substantial collection of physical discs, black and silver, and I play them often. But I love the convenience of my network-attached storage (NAS) appliance, Qobuz, even lossy Spotify, especially when I want my world filled with music for hours with no thought or action on my part.
