With the growing success of OL DAC, JDS Labs presents OL DAC - USB Edition As we doubled the size of our most recent OL DAC production run, we acknowledged that only some of you add TOSLINK cables to your cart. Most only want USB input and never touch the optical jack. So, we removed the unnecessary S/PDIF controller and I2S routing circuitry to create the new $99 USB Edition. The new OL DAC - USB Edition offers driverless USB audio and remains 100% AC powered, like the original OL DAC, now aptly titled Optical + USB Edition. All performance meets or exceeds that of the original OL DAC. We’re pleasantly surprised to report that removal of the I2S MUX bumps USB Jitter components @11025Hz from an already great -116dB to -120dB! The USB Edition is available now via dropdown selection on the OL DAC product page.
