Then it is easier :) You sure also could replace the crystal with an 
HC-49/U (surely it has not an exotic frequency).

If you're so sensitive to the drift that a crystal could introduce in 
you HiFi gear, it could... If you're able to distinguish the difference, 
let us know (some people sells Rb clocks for driving cd-players, I 
personally think that they are sellers of modern versions of snake oil). 
I know that these coments could start a heated discussion about 
audiophiles and audiophools (I know from other forums...). Please, don't 
start it!
