Acoustic Revive RR-888 Ultra Low Frequency Pulse Generator: $695
This small plastic box with a wall wart power supply is said to artificially generate the electromagnetic 7.83Hz Schumann resonance and alter the sound in your listening room. “Which it most certainly does—alter the sound, that is,” wrote Alex Halberstadt. Listening to “Madness” from Miles Davis’s Nefertiti LP, he realized that the band’s tart, angular sound had become sweeter: “It was as though the dissonant and otherwise disagreeable sounds on the recording were somehow pushed down below the…

Ampsandsound Yellowstone: $25,000
This massive tubed preamp uses two 12AX7 (ECC83) twin triodes for line-input voltage gain; one 12BH7 as a driver; two 12AX7s for phono-input voltage gain; and one 12BH7 as a driver. There are also two 5AR4 rectifiers. The phono stage also uses 1:9 and 1:18 Cinemag step-up transformers. Listening to the phono input, Ken Micallef found that the Yellowstone was among the most neutral and transparent amplification machines he’d heard in-house. “It adds just a touch of warmth,” he wrote, “giving music a sweet liquidity and…

Theta Digital, the pioneer of digital separates, announces the mighty Prometheus monoblocks ($12,000/pair). Heard in pre-production mode, with bass so strong and tight that it sent me into the hallway to discuss the product, the 200Wpc into 8 ohms monoblock is due out "within 90 days" (to quote a mantra oft-repeated at CES 2013).
According to the company's designer, Dave Reich, the Prometheus is based on a European-sourced module, which is mated to Theta's own power supply, software, and hardware control. "Timing between switching on and off is crucial…
