Auralic LEO GX.1 Reference Master Clock

LEO GX.1, our reference master clock, continues providing trademark levels of performance in digital audio clocking. Offering “beyond-measurement” levels of precision, results detected while listening: a much wider sound stage, pinpoint instrumental accuracy, and dynamic range beyond expectation. By circumventing the DAC’s internal clock, shielding the unit from noise with an internal copper enclosure, and utilizing a new advanced multi-spring suspension system available on all G2.1 products, LEO GX.1 will dramatically enhance your listening experience. 


Benchmark:  Allan Deviation: 2E-12 (1 second), Equivalent Jitter: 500 times less than an 82fs femto clock (1Hz-10Hz), Equivalent Phase Noise: -110dBc/Hz@1Hz (Ref Frequency: 10MHz)
