PranaFidelity and Atma-Sphere
Named for the God of Wind, PranaFidelity's new 94 lb, Vayu/fs, two-way, quasi-linearray loudspeaker ($6950/pair), which has a claimed frequency response of 29Hz22kHz, an 8 ohm impedance, and 89.5dB sensitivity, was reproducing the exceedingly warm sound of Atma-Sphere's M-60 Mk.III.2, fully differentially balanced class-A, triode OTL monoblocks ($7200/pair) and MP-3 Mk.III.2 preamp ($5600$9000, depending upon options).
It got more than a little difficult trying to figure out what was going on as PranaFidelity's Steven Norber buzzed around, turning on and off the Vayu/fs speakers' high-end tuning circuits. Nonetheless, I could admire the very nice sound of a triangle on a classical LPs, and the tweeter's equally superior performance on a piano recording by Jessica Williams. Is the speaker's bass a little hooty, were the amps having difficulty controlling their low end, or was it the room that created both the hints of hootiness and the booming? I look forward to hearing the speakers again with more neutral electronics.
