Solid State Preamp Reviews

The most recent of these preamps was the MBL N11 that Jason Victor Serinus reviewed in July 2021, which was preceded by the Pass Labs XP-32 I reviewed in March 2021, the Benchmark LA4 Kalman Rubinson reviewed in January 2020, and going back even further, the Ayre Acoustics KX-R Twenty I reviewed in December 2014, which was one of the products Ayre released to celebrate its 20th year of operation.

I am now reviewing the KX-8 line preamplifier, which costs $6500 in basic form.

Enter Simaudio's Moon 891 network player/preamplifier ($25,000; footnote 2). Also called a "streaming preamplifier,"it includes a DAC that converts PCM and MQA files up to 32/384 (with 24-bit files upconverted to 32-bit) and DSD files up to 256. It also includes what Simaudio company co-owner Costa Koulisakis describes as "a fully configurable" MC/MM phono stage. Both theoretically and practically, it's an ideal solution for someone with space and/or budget constraints.

Today, the ascension of streaming as the conduit for both audio and video content has nudged these, too, from the center stage. One can stream content from the bewildering variety of products with internet access including cell phones, smart TVs, almost any computer, and of course, dedicated streaming devices from the cheap-and-cheerful to seriously audiophile. If your music is on the web or on a NAS, many of these will let you browse for it, find it, and play it.

Me, review a $150,000 preamp? This was not a kid in a candy store–scale event. This was a kid let loose in a big-assed candy factory–scale event.

My glucose levels spiked. Questions whirled. What new virtues might a cost-no-object, presumably state-of-the-art preamplifier bring to my reference system? Would images be more corporeal? Would the soundstage be wider and deeper, tonal colors more intense? Would bass—already fabulous—be even more solid? Would the Relentless preamp move me closer to a premium-seat-in-a-live-concert experience?

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!

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.

But when you look at a Rolls or a Bentley, you immediately recognize it for what it is, and you want to sit down in it. And so it is with McIntosh, except you don't want to sit down in it; you want to sit down in front of it, between the speakers of the hi-fi system it occupies.

The C12000 is McIntosh's current flagship preamplifier. It's part of McIntosh's Hybrid Drive series of products that combine tubes and transistors in interesting ways.
