Antelope Audio was showing their Rubicon Atomic AD/DA Preamp ($40,000) that offers up to 384kHz playback via its USB input, DLNA streaming via Ethernet, 1 Phono Input on RCA, 3 RCA, 1 HiZ Input on RCA, 1 Combo Balanced Input on XLR/¼ TRS, 2 S/PDIF, 2 TOSLINK, 1 AES/EBU, and Word Clock Input. Outputs include 1 Balanced XLR, 1 Unbalanced RCA, 2 S/PDIF De-jittered outputs, and Hi-Speed USB on standard B type connector.

That Atomic Clock in the Rubicon is, according to Antelope Audio, a jitter Terminator, "Rubicon is the first DAC to integrate a Rubidium atomic clock, which is 100,000 times more stable than a traditional crystal oscillator. Coupled with Antelope’s 64-bit Acoustically Focused Clocking technology, the Rubidium achieves a breakthrough in jitter management, improving the sound quality in an unprecedented way."
