Pasithea is the fruition of Cees Ruijtenberg’s vision on what Non-Oversampling (NOS)<\/a> R2R DACs can achieve, with\u00a0Sonnet Audio<\/a>‘s flagship overcoming the known challenges of this technology.<\/p>\n

Clear as water, the individual ripples of music are perfectly laid out for you without any murkiness.\u00a0It joined Twittering Machines<\/a>‘ list of Favourite Digital. SoundStage!<\/a> deem it worth its flagship asking price. Pasithea was a revelation to Alpha Audio<\/a>.<\/p>\n

Discover a truly reference DAC like Pasithea present NOS R2R as it should sound, discarding artificial soupy warmth for a clear, uncoloured pasture to music at frequency’s extremes.<\/p>\n

You’ll hear the natural micro and macro-dynamics of premium Dutch NOS R2R technology, reproduced faithful to the original file’s samples by Sonnet’s new top-of-the-line SDA-3 discrete resistor ladder modules \u2013 claimed to posses linearity, lower distortion and a noise floor 10 dB lower than the Morpheus<\/a>. [See Product Desc. For More]<\/strong><\/p>\n

No oversampling digital filter stands in the way of music, giving you near-perfect time-domain impulse with excellent phase response, helped by frequency response that doesn’t truncate abruptly confined to obeying Nyquist laws.<\/p>\n

But don’t let Sonnet’s unprocessed lack of digital additives detract from its technical prowess \u2013\u00a0Ruijtenberg’s and Co-Founder Lion Kwaaijtaal’s<\/span> technique of splitting a datastream’s Most-Significant Bits (MSB) from its Least-Significant Bits (LSB) and decoding them separately for extreme dynamic range is proprietary.<\/span><\/span><\/p>\n

With a forward correction technique first employed to great effect at Metrum Acoustics, Ruijtenberg repeated the trick at Sonnet. Each of Pasithea’s eight SDA-3 DACs contains an FPGA that separates the LSBs from the MSBs. Then, Pasithea increases the level of LSBs and decodes them as if they were MSBs, routed to the same, optimal top half of the SDA-3’s resistor ladders.<\/span><\/p>\n
