To me, mystery and beauty are synonymous. Consequently, I have steered my years so that I am always engaged in a search…

In my realm, the most sophisticated, intelligent, difficult thing anyone can do is create something mysterious. It could be a poem, a photo, a movie, a song, a symphony, or a piece of painted wood. What's most important is the mystery—and that experiencing the mysterious creation inspires in the observer a desire to probe its hidden realms, to somehow figure it out. Human cultures are founded on mysteries: Mysteries incite art, inspire science, and facilitate dreaming.
When I flipped the Mighty's deck-mounted switches to engage triode operation, the sound with the Falcons became more pure by several notches—and also more color-saturated.
In UL mode, Chesky Records' first release, Hector Berlioz's Symphonie Fantastique: Opus 14 performed by The Royal Philharmonic conducted by Massimo Freccia, recorded by Kenneth Wilkinson in 1962 for a Reader's Digest box set (LP CR-1), sounded powerful and micro-focused but also grayed and a little brittle.
In triode mode, the Mighty's pentodes made the strings of The Royal Philharmonic glow. I could…
"Dear audio enthusiast." Those were the user manual's introductory words, not "Dear audiophile." I stared at them for a few seconds, letting the implication of that greeting sink in. I don't know if it was meant this way—perhaps not—but for me, this was a whistle call announcing that the KLH Model Three ($1799.98/pair) was not intended for those obsessed with having the best at all costs; it was meant for people who dig quality sound, period. It was also meant for people who dig that vintage-American-speaker look.
At first glance, the Model Three—I'll call it the M3 for short—may seem…
"First, check that the woofer is securely fastened to the baffle," unaware that I was hearing the same thing from both speakers. "The screws might have come loose in shipping. Second, if the woofer screws are tight, it is possible that either the complete crossover or one of its components, most likely a heavy inductor, has come loose in shipping. If you can't get inside the speaker to check this, I think you should ask for new samples."
Whaaa? New samples? No! I had a deadline!
I pressed. "Could it be because the Model Three is a sealed box? That the lowest note is creating…

Sidebar 3: Measurements
I used DRA Labs' MLSSA system with a calibrated DPA 4006 microphone to measure the KLH Model Three's frequency response in the farfield and an Earthworks QTC40 mike for the nearfield response of the woofer, both microphones used with an Earthworks preamplifier. I measured a different sample than those auditioned by Robert Schryer; its serial number was 20220401101.
The Model Three's excellent manual includes a lot of useful advice on optimizing the balance of the speaker. A diagram indicates that with the Model Three sitting on its stand, the listener's…
The Topping DM7 DAC ($599.99) is a high-resolution, eight-channel DAC that supports PCM and DSD sources but will not handle any of the common Dolby/DTS codecs. It employs the highly capable and respected ES-9038PRO DAC chip, ESS's flagship. It has just one input, and it's USB. Its eight analog outputs are fully balanced, but they are TRS (tip-ring-sleeve) phone jacks, which are more widely used in pro audio; most audiophiles will require adapters. Finally, it includes a master volume control and individual channel gain controls (all with 0.5dB resolution), but the finicky up/down buttons on…
The purity delivered by—or via—the DM7 recurred again and again, and often it was a surprise. The album An Unexpected Mozart (Harmonia Mundi HMM90239697, auditioned from a 24/96 download) is aptly named not only because of its surprising instrumentation (including, in addition to voice, mandolin, harpsichord, and organ, also glass harmonica and musical clock). And not—or not only—because in addition to pieces by Mozart, this album named for Mozart includes contributions from Haydn and C.P.E. Bach. Nor is it just because it is performed, under the direction of Louis-Noel Bestion de Camboulas…
