I measured a different sample of the Naim NAP 250, serial number 518784, than that auditioned by Martin Colloms. I performed the measurements with my Audio Precision SYS2722 system after preconditioning the amplifier by following the CEA's recommendation of running it at one-eighth the specified power into 8 ohms for 30 minutes. At the end of that time, the cooling fan on the rear panel had turned on but the sidemounted heatsinks were very hot, at 127.1°F (52.9°C), and the top panel was only slightly cooler, at 116.4°F (46.9°C).

How do you know you're beyond help as a card-carrying audiophile? For me, it happened during a recent trip to Italy. Several times a day, my thoughts drifted to the Focal Maestro Utopia Evo speakers that had been delivered two days before I left for Europe. At one point, I considered FaceTiming the housesitter to request a live view of the listening room, where the Maestros were playing music, breaking in.
Chrissakes! Couldn't I just enjoy la dolce vita? Savor the belly-busting meals in Treviso and Civitavecchia, surrender to Tuscany's soul-soothing landscapes, thrill to Rome's old-world…
Maestro, musique!
Through the Maestro Evos, the bass on Metropolis's "Planners and Thinkers" (16/44.1 FLAC, Soundtrack Classics/Tidal) slammed so deep and turned so seismic, it was almost scary. My room is built on a concrete slab with rubber subflooring, but damned if my chair didn't shake. I'd accidentally clicked the "loop track" button in Roon and was powerless against the repeats. The sound was so satisfying that I let the recording play four, five times in a row.
I also got bruising bass on "Prism" by British trip-hop outfit Submotion Orchestra (16/44.1 FLAC, SMO/Qobuz…

When I learned that Rogier van Bakel was reviewing Focal's Maestro Utopia Evo, I flashed back to the logistical difficulties I experienced when I reviewed an earlier version of this loudspeaker, the Maestro Utopia III, in July 2010. The Evo is the same size—almost 5' high—and weight—256lb—as the earlier speaker. It made sense, therefore, to drive my test gear the 500 miles to RvB's place in Maine rather than struggle with the loudspeaker's bulk at my Brooklyn home.
For the measurements, I drove one of the Focal Maestro Utopia Evos, serial number A1BPEF00543…
Why is John Coltrane's A Love Supreme still so resonant nearly 60 years after it was recorded? Much to its credit, it's short (just over 30 minutes) and to the point. If you're going to raise a prayer of gratitude to a higher power and layer spiritual meaning onto music, best not belabor the point. In the case of A Love Supreme, that kind of brevity also extended to the recording process. The album was tracked in one day—December 9, 1964—by Rudy Van Gelder in his studio in Englewood Cliffs, New Jersey; Van Gelder also mixed the album. A composed (rather than purely improvised) four-part suite…

If you've read any of my previous Dreams, you no doubt realize that I am an empiricist by trade—that I believe in the value of relaxed, mindful observation, especially if my solitary observances are independently corroborated by others. Whenever possible, I test my observations by getting either the Spin Doctor, the Audiophiliac, or my Russian neighbor to listen and tell me what they notice. If they notice the same things I noticed, independently, I relax. Corroboration is important because when I submit a review, I have an obligation to get it right. I need to be confident that readers, when…
