Simaudio Moon 860A v2 power amplifier

We've all been in similar situations. We approach an undertaking with the highest of expectations. Then reality intervenes, expectations change radically, and we have another story to tell, post on social media, or use to begin a review.

This tale of altered expectations began a few years after my birth, at AXPONA 2022, where I covered several stellar-sounding rooms that included Simaudio Moon electronics. By the third such room, I'd resolved to contact Simaudio, check in with Jim Austin, and see if there was a product that made sense to review in my system.

LKV PWR-3 power amplifier

Reviewing LKV Research's Veros PWR+ power amplifier in the September 2020 issue, Senior Contributing Editor Herbert Reichert enthusiastically opined, "the class-D LKV amp played equally rich and atmosphere-soaked through the entire audio band. It did atmospheric dreamy like class-A does atmospheric dreamy." Herb concluded, "Sound quality and music enjoymentwise, the LKV Research Veros PWR+ amplifier sits on a higher mountain than any other class-D amp I've encountered."

Gryphon Apex Stereo power amplifier

Some time ago, an amplifier in for review caught fire when first powered up. I don't mean it smoked and sizzled and shut down—I mean that actual flames shot through the top grate. Fortunately, I was able to grab a kitchen fire extinguisher and douse the thing with foam. (Sorry, this was decades ago, and I don't remember the brand, but I think the company had a fire sale and was shut down.)

Rotel Michi S5 power amplifier

Like an immense night bird aloft in the gold'n sky.
I should like to sail off towards islands of flow'rs
While list'ning to the perverse sea singing
In its old and bewitching rhythm.

It took some time to figure out why, in the middle of auditioning Rotel's Michi S5 stereo power amplifier ($7499.99) with the room-shaking opening of Richard Strauss's Also Sprach Zarathustra, Ravel's far subtler and perfumed setting of Tristan Klingsor's lyrics from Shéhérazade came to mind.

Luxman M-10X power amplifier

As I started to write this review, the news broke that Sound United, the owner of Boston Acoustics, Bowers & Wilkins, Classé, Definitive Technology, Denon, Marantz, and Polk, was going to be purchased by a corporation that makes medical instruments. Such consolidation is not new. China- and UK-based International Audio Group (IAG) was one of the first organizations to acquire iconic audio brands. IAG owns Audiolab, Castle, Quad, Leak, Mission, and Wharfedale. In 2009, they purchased Luxman.

darTZeel NHB-108 model two power amplifier

Like the proverbial pot of gold, darTZeel's golden equipment beckons. That, at least, is how it felt in January 2010, when John Atkinson and I ended our coverage of T.H.E. Show Las Vegas in the room shared by darTZeel, Evolution Acoustics, and Playback Designs. Listening to darTZeel's discontinued NHB-458 monoblocks (footnote 1) and NHB-18NS reference preamplifier (now updated), I was transfixed by the fullness of the system's midrange and overall beauty of the sound. "It was as though the system was opening its heart and welcoming us in," I wrote. "That's how warm and nurturing the sound was."

Accustic Arts AMP V power amplifier

The $50,000, 176lb Accustic Arts AMP V (pronounced Amp Five) is the heaviest, tallest, most powerful, most expensive stereo amplifier to enter my audio system. With rated power of 900Wpc into 8 ohms, 1360Wpc into 4 ohms, and 1500Wpc into 2 ohms, the AMP V, which stands proud at the top of the Accustic Arts amplifier line, surpasses my reference D'Agostino Progression M550's rated power into 4 ohms by 260Wpc.

Dan D'Agostino Master Audio Systems Progression M550 monoblock power amplifier

We audiophiles so frequently get caught up in the pursuit of perfection that some have attempted to rebrand high-end audio as "perfectionist audio." But is it even possible for a single piece of audio gear, let alone an entire audio system, to attain perfection when there's no common agreement as to what "perfection" means? It's easier to cue up a Nirvana track than to find the way to audio nirvana.

Rotel Michi M8 monoblock power amplifier

In an April 2020 press release, the McIntosh Group announced that its subsidiary brand Sumiko, which was cofounded by the late Dave Fletcher and distributes Sonus Faber and Pro-Ject among other high-performance brands, had secured distribution rights for Rotel Electronics in the US and Latin America. That press release prompted memories of a Rotel RP-3000 direct drive turntable I once owned, fitted with a Lustre GST arm.

NAD C 298 power amplifier

Power amplifiers should be boring. They have a single, well-defined function: Make the input signal large enough to run a loudspeaker so that it makes sound at levels suitable for listening to music. Generally, controls and features are few or none. Peter Walker of Quad famously defined the ideal amplifier as a "straight wire with gain." That's just one feature: gain.
