"Why someone in their right mind would pay $5,500 for this vs. a few hundred dollars on a NUC?" "The short answer is for the sound."
"Moreover, prior to the arrival of the 432 EVO, my system, anchored by the Schiit Audio Yggdrasil OG DAC, Pass Labs XP-12 preamplifier, X150.8 amp, Straight Wire reference cabling, and Usher Mini Dancer 2 loudspeakers, has never sounded better."

"But bottom line, the 432 EVO yielded a more organic, natural sound to vocals and instruments when playing in the 432 Hz mode. Now, at 440 Hz, the differences were negligible. So, if you like that added warmth and other pleasant qualities that 432 Hz imparts on the signal enough to warrant the purchase, and you have the funds, then definitely! If not, keep your money. Let’s face it: some people--even some reviewers--prefer 440 Hz. That’s not a bad thing."
