Right. So it makes you wonder how he reached the conclusion the Big Ben produced a gigantic "improvement." Here's my suggestion. Go back to the studio where you (he) heard the big difference. Set it up exactly the way you did. Listen. Oh boy, do you still hear the difference?
Hmmm... now let's see EXACTLY how much of a dfference it really is. I imagine you first listened on internal clock. Then you rewound and you listened on Big Ben clock. I think ANYONE can convince themselves of ANYTHING when they listen that way, especially if it's not blind. If you're convinced you're going to like one over the other, especially, the second listen will sound better, every time.
At the University of Miami, they teach students a lesson with "the red light trick". First you do a listen with the red light off. Then you do a listen with the red light on. Even if the two sources are identical, the listen with the red light on always sounds better! It's the way our brains are wired...
So, here's how apparently GIGANTIC differences can be reduced to reality. If this is an A/D, good, now you can do a REAL TEST instead of one that will fool you almost every time. Record the output of the A/D under both clocks to two different files. Now, listen to the two files, switching back and forth while under a single clock. OK, now, do you still hear a GIGANTIC difference? If it was the RME converter with its excellent jitter rejection, I wonder if you will hear any diference at all!
