Budget Component Reviews

The marriage of little streaming computers to DACs was at first a shotgun thing, a way to add Swiss Army knife capabilities at a price point. That was back when it was cutting-edge to have a NAS server full of digital files on the home network, and when commercial streaming was new, primitive, and lossy. Remember Pandora? Cool idea, but who wants to sit through ads and not be able to skip over more than a handful of disliked tunes every hour. Then Spotify came along. Then Apple and Amazon jumped in, and that's all she wrote. Eventually, streaming even got around to us audiophiles who desired lossless audio of at least CD resolution. Viva Qobuz!

The EXN100 is Cambridge Audio's state-of-the-art streaming DAC. It's half of the new EX line; the other half is the EXA100 integrated amplifier.

A few summers ago, I briefly got it in my head that I could become a wine connoisseur. This was due to a very generous and unexpected gift. A local acquaintance had passed away, and his wife wanted to rid her basement of his small wine collection.

I don't know why I was chosen as the lucky recipient, but after stammering half a dozen thank-yous, I suddenly owned about 150 fine wines. A few carried four-figure price tags.

Reliably telling a Pinot Grigio from a Chardonnay isn't part of my skill set. Grape varieties, terroir, vintages? You might as well ask a toddler to become conversant in quantum mechanics. Still, I was intrigued by the bottles and amused by the ridiculousness of the situation. Me, an oenophile? I supposed I could pretend, and I did.

After opening and drinking, with my wife, a 1988 Château Léoville Barton, I wrote an over-the-top review and emailed it to a wine-loving friend for his amusement. "I beheld Hawthorn berries and beef stock along with a suggestion of blonde tobacco. Other than the obvious green walnut, there was a top note of wet Baja beach at dawn, mixing subtly with minke-whale flatulence and a hint of two-day-old scallop innards. Finally, with subsequent sips, I detected the aroma of the well-worn merkin of a Honduran sex worker. All in all, not a bad wine."

Eat your heart out, Robert Parker!

For music listening circa 2024, streaming is both the present and the future. Physical formats are still around, and they are still the best choice in some cases, as with deluxe reissues of beloved albums, which may add value with extra live performances, full-resolution surround sound, and other perks. The niche vinyl market continues to thrive, and that business model obviously works for releases of a few thousand copies. (It also works, apparently, for releases of hundreds of thousands of T-Swift platters to be displayed on shelves and hung on walls.)

But facts is facts: Streaming is now the only mass medium for listening to recorded music—the primary carrier for music—and has been for a few years now. According to RIAA statistics, the crossover year was 2016. That's when, in revenue terms, streaming outpaced physical formats. By 2022, the latest full year tabulated, streaming accounted for 84% of US recorded-music revenue.

So what's a long-time audiophile, born into the analog world, with strong roots in physical media, supposed to do?

Do you remember your first really decent hi-fi system? It opened up your music, teased your brain with the possibilities of thrilling aural excitement, of dives to the bottom of the musical ocean. Perhaps it was all you needed, but more likely it was the beginning of a quest for your own ultimate sound-induced bliss.

That quest may be ongoing and never-ending, because our tastes and preferences evolve over time, money comes and goes, and we're simply never satisfied. And even if we are, eventually, we're audiophiles, and the industry always offers something interesting and new, or something old that's new again.

My time with a pair of Klipsch The Nines speaker-gadgets reminded me of the exciting, youthful bloom of my first serious sound system: a Technics SL-D2 turntable with Audio-Technica cartridge, a Philips 45Wpc receiver, and New Advent Loudspeakers.

Sometimes I think expensive components—I'll let you decide what constitutes expensive—should come with a big red sticker on the box that reads "WARNING! This product will probably not meet your expectations!" That's because when you spend a lot of money on something, you expect that something to have no flaws and to sound nigh perfect. Why else would you have paid so much? As you gaze at it, touch it, and listen to it, it constantly reassures you that you made the right decision by picking it over all the other, less pricey candidates. It has to be unambiguously better than any component of its nature that has passed through your system, or else, what was the point in all that upgrading?

Prior to this review, I had expectations about the product under review, the Leak Stereo 230 ($1695 with the walnut enclosure), based on, among other factors, price.

Characteristically, the email from Kal Rubinson got straight to the point: "I have a WiiM Mini that I have played with, but I am not the right one to review this as I am not sufficiently interested in or knowledgeable about wireless streaming. It ... can handle uncompressed PCM via its DACs." "I'll review it," I replied, intrigued by a $99 D/A processor that can stream hi-rez audio via Wi-Fi and that also has an analog input so it can act as a preamplifier.

What am I doing with a vacuum tube preamplifier? I haven't owned a tubed preamp since I bought a Sonic Frontiers Line 3 preamplifier at the turn of the century. I set that aside within a few years as I moved into multichannel because multichannel tube-based electronics were, and still are, rare. My last home experience with a vacuum tube was with a PS Audio Stellar M1200 monoblock power amp, which is a hybrid with a 12AX7-based input stage.
