To put it in perspective: today's best DAC chip available claims no better than 22 bits of dynamic range and only 20 bits of linearity. High-resolution music deserves better than that. To accommodate this, Mola Mola's DAC is designed using circuits and digital algorithms developed entirely in-house.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eThe converter is a two-board stack that fits into one of the preamp's option slots. On the first board, all incoming digital audio is upsampled to 3.125MHz\/32 bits and converted to noise-shaped PWM. On the other board are two mono DACs: a discrete 32-stage FIR DAC and a single-stage 4th-order I\/V converter with 4th-order filtering, which converts the PWM into analogue with a breathtaking 130dB SNR.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eThis is near the theoretical limit for 24-bit files and far beyond that of even quad-speed DSD. Uniquely, distortion remains below the noise floor even for full-scale signals. A quick look at current and historic trends of high-end ICs indicates that for the foreseeable future, this kind of performance will remain unavailable to manufacturers forced to rely on the same 'chip du jour” that also powers their competitors' products.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eEven by today's exacting standards, extraordinary care has been taken to deal with jitter. Mola Mola's DAC uses a home-grown asynchronous upsampling algorithm whose input frequency measurement slows down rapidly until, after a few seconds of lock, the frequency ratio measurement is frozen. Frequency stability is then wholly determined by the internal clock, a laboratory-grade 100MHz SC-cut oscillator. This is effectively an atomic clock sans the physics package (which contributes nothing to spectral purity but quite a lot to cost).\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cspan\u003eKey Features\u003c\/span\u003e\u003c\/h2\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan\u003eInputs and Outputs\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eAES\/EBU (XLR)\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eOptical (Toslink)\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eUSB type B\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eBluetooth (SBC, AAC, APTX, LDAC)\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eEthernet (Roon Ready)\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cspan\u003eSUPPORTED FORMATS\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003ePCM up to 384kHz\/32 bits (\u0026gt;192kHz and \u0026gt;24 bits via USB and Roon only)\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eDoP and Native DSD up to quad speed (USB and Roon only)\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cspan\u003ePERFORMANCE\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eFull-Scale Output Level: 20dBu\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eSignal to Noise Ratio: 130dB\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eTHD, IMD: not measurable (estimated -140 dB)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eBandwidth: Up to 80 kHz (apodizing response)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eIntegrated jitter: \u0026lt;1ps from 10Hz upwards, \u0026lt;300fs from 1kHz upwards\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eJitter rejection: \u0026gt;80dB at 1Hz after 20 seconds of lock\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/section\u003e\n\u003c\/center\u003e\u003c\/section\u003e\n\u003c\/header\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/form\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"The Music Room","offers":[{"title":"Default Title","offer_id":51268133191961,"sku":"0488newMOLA","price":8990.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/Mola_Mola_DAC_Upgrade_for_Makua_Kula_1.jpg?v=1768038572","url":"https:\/\/tmraudio.com\/products\/mola-mola-dac-upgrade-for-makua-kula","provider":"The Music Room","version":"1.0","type":"link"}
