Solid State Preamp Reviews

Ever notice that the language we use to talk about sound can be pretty aggressive? Reviewers often write about amplifiers "taking control" of a speaker, possibly "ironfisted control," especially if the amplifier in question happens to be a "juggernaut." In this particular linguistic trash fire, we also find "razor-sharp transients," "hair-raising dynamics," and that ickiest of descriptors, "bass slam." If words could smell like hair gel and drugstore cologne, these might.

All this verbiage is describing brute force, which we might use to push open a heavy door. But there's another kind of force that we encounter in the world, and consequently in audio, captured in the expression "life force." It denotes a sense of vitality and presence that isn't readily perceived by the senses—something lingering just out of reach of our rational minds. This force can be experienced in the terse saxophone solos of the young Sonny Rollins, the eerie abstract paintings of Mark Rothko and Pat Steir, and the deceptively quiet poems of Elizabeth Bishop. If you've ever been drawn in by one of the squat, gouged, lopsided jars made by a traditional Japanese potter, you know what I'm talking about.

I can roll out of bed and install a $10,000 phono cartridge while finishing my coffee, but I postpone DAC installations until I am in the exact right mood to handle the potential stress—especially DACs with a touch screen and a complex menu. To my delight, Ferrum Audio's new Wandla digital converter was completely stress-free to install. It took only minutes to connect the USB-C cable, the Cardas Audio Clear Beyond interconnects, and 24V DC power adapter.

Connecting the power adapter caused a power-switch symbol to appear on the front panel touch screen. The moment I touched it, I smiled like the Cheshire Cat, because I saw a USB-C symbol, a loudspeaker symbol, three dots in a box, and a volume control bargraph. That told me the Wandla recognized my chosen input and was waiting for a signal. All that remained was for my Roon Nucleus+ server to recognize and enable the new DAC, which it did without prodding or reprimand. For me, that was a wow moment, a good start to what promised to be an interesting review.

Naim has comprehensively reimagined its Classic Series, which has been around for some 20 years with improvements along the way. Included in the new range of products is the 200 series, comprised of two products: the NAP 250 power amplifier, which I reviewed in the November 2023 issue of Stereophile, and the NSC 222 streaming preamplifier ($8999), which is reviewed here. A third component in the New Classic series, the NPX 300 power supply (also $8999), which is intended to be paired with the NSC 222 and other Naim components, is also considered in this review.

The concept of streaming digital music files over distances great (as with internet-streaming services like Spotify, Qobuz, Tidal, etc.) and small (from a home-PC hard drive, NAS, or networked music server) became mainstream only recently. But it was already brewing during the late 20th century, with people illegally downloading low-bitrate MP3 files made from CD rips and coming close to killing the recorded-music industry.

That wasn't streaming exactly, or not in the current sense, because the files needed to be downloaded, stored locally, then either played out of a computer or loaded onto a portable player, but from that point forward it was a steady march to the streaming-dominated present.

Never mind Napster—the first subscription audio "streaming" service was one you probably wouldn't think of: Audible, the audio book service now owned by Amazon, which started up in 1995. I did beta testing and editing work for early-days Audible, and around that time, I started loading up home-ripped MP3 files on a pocket-sized Rio MP3 player (which by then had replaced Audible's proprietary player), using it in place of a portable CD player. This led to experiments with a PC music library/player running Linux, controlled by a Handspring PalmOS device connected to the stereo system via a Sound Blaster 16 card.

Hygge might not be the first word that comes to mind when contemplating the Primare PRE35 Prisma preamplifier, but in Limhamn, Sweden, that is how Primare likes to describe their products. It means "cozy," and it's a very important concept in the Nordic countries, almost a way of life. Another term that appears in Primare's product descriptions is lagom, which loosely translates as "not too little, not too much—just right."

Three high-performance products were subjected to second opinions and/or measurements in recent issues: Channel D's Lino C 3.3 phono preamplifier, Mola Mola's Tambaqui D/A processor, and Pass Labs' XP-32 line preamplifier.

Are well-heeled audiophiles ready for a knob-free future? Gryphon Audio Designs thinks so. In contrast to Gryphon's volume knob–dominated Pandora preamplifier, the Danish company's new Commander offers nothing on its bold front panel to grab or turn.

Instead, there's a large, extra-thick, triangular glass protuberance that extends dramatically below the chassis's vertical dimension. That's where you'll find an "on/off" button, the main unit's only physical switch.
