dCS Rossini Owners - sonic differences with and without the clock

What's an "Objective" revew???

I bought a Rossini and clock together.  I first only hooked up the DAC and was floored by the sound so much that I just didn't even bother with the clock and figured I'd get accustomed and then the clock would be a nice upgrade later.  I went from USB input to ethernet on the DAC which was a small improvement but easier and more convenient via ethernet.  When I added the clock I wouldn't call it night and day for me but yes it clearly gives you more of a good thing.  I don't think you want to try the clock unless you are willing to shell out the money for it, once you try you won't want to go back.  But the Rossini is really good alone and if you are enjoying immensely then just keep doing that until you are itching for more and better then get the clock.  

Why dont they just put the better clock in the rossini and charge a little more....not sure why you need good and better clock same company for same dac....let me guess the top of the line dac has option for better yet external clock?

Separate boxes in order to maintain proper temperature control for the clock is part of the reason. I own a Rossini and clock and agree the clock raises the performance of the DAC. I have found the digital BNC cable between the two to be an important link for best SQ.
