Dcs clock jitter specs

I read how Greg raved about the perf10 and then got the novus 1 with improved accuracy but i cant find any reference indicating what kind of improvement is expectedbor yielded. I am mentally committed at least to the perf10 but dont want to go down that road if the best new atomic clock is already out of the bag and i have just missed it. Has anyone tried the perf10 and think they have found something substantially better. Even marginally better. I saw that Greg had to install antennas on his roof to get separate satellite signals for reference. I can understand easily that it yields substantially better accuracy on the clock. Does that translate to substantially better music rendition. I have plenty of room for the multiple antenna but am looking for a reality check. Not looking for a new hobby. Just great sound reproduction.

Anybody?

Currently using vivaldi clock, fiber between cat 5 and switch transparent reference cables throughout.
