By no means am I going to pretend to understand what a Rubidium atomic clock — which is 100,000 times more stable then the more traditional crystal oscillator — has anything to do with sound quality, but I do know that the Rubicon Atomic Preamp ($TBA) is the first Preamp to have one built in. it also has Antelope's 64-bit Acoustically Focused Clocking technology, DLNA support, 384 kHz USB streaming, dual stage headphone amps, and dual S/PDIF DE-jittered outputs all built into this crazy, and clearly super expensive item.
